Nitrogen Triiodide Chemistry Demonstration

Nitrogen Triiodide Chemistry Demonstration In this spectacular chemistry demonstration, crystals of iodine are reacted with concentrated ammonia to precipitate nitrogen triiodide (NI3). The NI3 is then filtered out. When dry, the compound is so unstable that the slightest contact causes it to decompose into nitrogen gas and iodine vapor, producing a very loud snap and a cloud of purple iodine vapor. Difficulty: Easy Time Required: Minutes Materials Only a few materials are required for this project. Solid iodine and a concentrated ammonia solution are the two key ingredients. The other materials are used to set up and execute the demonstration. up to 1 g iodine (do not use more)concentrated aqueous ammonia (0.880 S.G.)filter paper or paper towelring stand (optional)feather attached to a long stick How To Perform the Nitrogen Triiodide Demo The first step is to prepare the NI3. One method is to simply pour up to a gram of iodine crystals into a a small volume of concentrated aqueous ammonia, allow the contents to sit for 5 minutes, then pour the liquid over a filter paper to collect the NI3, which will be a dark brown/black solid. However, if you grind the pre-weighed iodine with a mortar/pestle beforehand a larger surface area will be available for the iodine to react with the ammonia, giving a significantly larger yield.The reaction for producing the nitrogen triiodide from iodine and ammonia is:3I2 NH3 → NI3 3HIYou want to avoid handling the NI3 at all, so my recommendation would be to set up the demonstration in advance of pouring off the ammonia. Traditionally, the demonstration uses a ring stand on which a wet filter paper with NI3 is placed with a second filter paper of damp NI3 sitting above the first. The force of the decomposition reaction on one paper will cause decomposition to occur on the other pa per as well. For optimal safety, set up the ring stand with filter paper and pour the reacted solution over the paper where the demonstration is to occur. A fume hood is the preferred location. The demonstration location should be free of traffic and vibrations. The decomposition is touch-sensitive and will be activated by the slightest vibration.To activate the decomposition, tickle the dry NI3 solid with a feather attached to a long stick. A meter stick is a good choice (dont use anything shorter). The decomposition occurs according to this reaction:2NI3 (s) → N2 (g) 3I2 (g)In its simplest form, the demonstration is performed by pouring the damp solid onto a paper towel in a fume hood, letting it dry, and activating it with a meter stick. Tips and Safety Caution: This demonstration should only be performed by an instructor, using proper safety precautions. Wet NI3 is more stable than the dry compound, but still should be handled with care. Iodine will stain clothing and surfaces purple or orange. The stain can be removed using a sodium thiosulfate solution. Eye and ear protection are recommended. Iodine is a respiratory and eye irritant; the decomposition reaction is loud.NI3 in the ammonia is very stable and can be transported, if the demonstration is to be performed at a remote location.How it works: NI3 is highly unstable because of the size difference between the nitrogen and iodine atoms. There is not enough room around the central nitrogen to keep the iodine atoms stable. The bonds between the nuclei are under stress and therefore weakened. The outside electrons of the iodine atoms are forced into close proximity, which increases the instability of the molecule.The amount of energy released upon detonating NI3 exceeds that requ ired to form the compound, which is the definition of a high yield explosive.

How Senators Use the Filibuster to Stop Legislation

How Senators Use the Filibuster to Stop Legislation The term filibuster is used to describe a tactic used by members of the U.S. Senate to stall or delay votes on legislation. Lawmakers have used every trick imaginable to filibuster on the floor of the Senate: reading names from the phone book, reciting Shakespeare, cataloging all the  recipes for fried oysters. The use of the filibuster has skewed the way legislation is brought to the floor of the Senate. There are 100 members of the upper chamber in Congress, and most votes are won by a simple majority. But in the Senate, 60 has become the most important number. Thats because  it takes 60 votes in the Senate to block a filibuster and bring an end to unlimited debate or delay tactics. Senate rules allow any member or group of senators to speak as long as necessary on an issue. The only way to end the debate is to invoke cloture, or win a vote of 60 members. Without the 60 votes needed, the filibuster can go on forever. Historic Filibusters Senators have effectively used filibusters or more often, the threat of a filibuster to change legislation or block a bill from being voted on the Senate floor. Sen. Strom Thurmond gave the longest filibuster in 1957 when he spoke for more than 24 hours against the Civil Rights Act. Sen. Huey Long would recite Shakespeare and read recipes to pass the time while filibustering in the 1930s. But the most famous filibuster was conducted by Jimmy Stewart in the classic film Mr. Smith Goes to Washington. Why Filibuster? Senators have used filibusters to push for changes in legislation or to prevent a bill from passing with less than 60 votes. It is often a way for the minority party to yield power and block legislation, even though the majority party chooses what bills will get a vote. Often, senators make their intent to filibuster known to other senators to prevent a bill from being scheduled for a vote. Thats why you rarely see long filibusters on the Senate floors. Bills that will not be approved are rarely scheduled for a vote. During George W. Bushs administration, Democratic senators effectively filibustered against several judicial nominations. In 2005, a group of seven Democrats and seven Republicans - dubbed the Gang of 14 - got together to reduce filibusters for judicial nominees. The Democrats agreed not to filibuster against several nominees, while Republicans ended efforts to rule filibusters unconstitutional. Against the Filibuster Some critics, including many members of the U.S. House of Representatives who have seen their bills pass in their chamber only to die in the Senate, have called for an end to filibusters, or to at least lower the cloture threshold to 55 votes. They allege the rule has been used too often in recent years to block important legislation. Those critics point to data that show the use of the filibuster has become too common in modern politics. No session of Congress, in fact, had attempted to break a filibuster more than 10 times until 1970. Since then the number of cloture attempts has exceeded 100 during some sessions, according to the data. In 2013,  the Democratic-controlled U.S. Senate voted to change the rules on how the chamber acts on presidential nominations.  The change makes it easier to set up confirmation votes for  presidential nominees for executive branch and judicial nominees with the exception of those for the U.S. Supreme Court by requiring only a simple majority, or 51 votes, in the Senate.

Personal Reflection Essay Example | Topics and Well Written Essays - 1000 words

Personal Reflection - Essay Example I thought writing by explanation or simply retelling a certain story where the main idea comes from another author or perhaps another person’s idea would be a lot safer and easier as you would only have to expound on what an author’s line or idea meant and adding up a little commentary on yours which would not really welcome new thoughts that might not be accepted by your readers. In a way, writing this way would give you less need to think and just more of taking it from someone else’s point of view. However, through the whole course, I realized that writing made up of mostly explanations is something that people would probably think the same as already, which defeats that whole thrill of giving your readers something new and personal. We all know that we read books, journals, or blogs to be able to get something new or to feed any curious thought. Thus, I have learned to move forward by encroaching my writing with exploration which is the next level of writing I learned in the course. This is the fact that I would say I enjoyed a lot learning as a writer, as I would now feel braver to insert new thoughts, parallel or not to my readers’ thoughts, express myself even when it sometimes seems like no one will agree, and at the same time get excited with the fact that someone else is going to read something that comes from what I think. Indeed, writers need not be scared of one’s audience. After all, that is why there are different genres of books because of the different depth and trail of thoughts that are always welcome in writing. In the end, you would not have to blame yourself for giving your readers a lousy or totally strange read because they picked you and not vice versa. Realizing these, I had the guts to write not only based on the sources or principles given me to explain but moreover, explore in my writing like I would explore a new place or perhaps check out someone I am really interested in. Of course, though writi ng is really a very interesting thing to do, I would say that it also has challenges to give you as a writer. For me, one of the greatest challenges I faced in the whole course would be learning about analysis and synthesis and applying these two in my writing. This is because of the fact that both would require one to see beyond a certain topic, fact, or perhaps a thought and be able to unite it with one’s thoughts even when all the while there is not a thing you truly are interested with or hold true. Aside from that, I think that another strong challenge I faced would be having to write a beautiful piece that had to describe a great experience when all the while I was feeling a different mood, specifically sad and disinterested. I handled this challenge by changing the basis of everything I write from the goal of the task instead of my emotions. Although emotions play a big part in influencing the mood of one’s writing, it is important to go beyond emotions and go b eyond that by transcending oneself to the state of mind a certain topic would require you to have. Also, I learned that I should divert focusing on what I see to what people see. I veered away from using myself as the center point of my writing and put myself in the shoes of those people whose thoughts I have to analyze and interpret.  Ã‚

The Three Little Pigs. James, sit still Essay Example for Free

The Three Little Pigs. James, sit still Essay My first graders took a seat on the carpet for our first story time, and I began to read, The Three Little Pigs. James, sit still. The children looked around. Was the books title Three Little Pigs James Sit Still? They realized I was talking to one of their classmates, who was rolling on the floor. I continued, The first little pig built his house of†¦James, stop wiggling, stop touching that. What should have been a simple task of reading the book, showing the pictures and stopping to discuss each problem the pigs faced was becoming increasingly difficult. I read on, trying to ignore the disruptions. CRASH! The chair James had been rolling under had fallen over and knocked a crayon box off of my desk. The loud noise interrupted the story and the children complained, James, Miss Gigout cant even finish a page. Youre messing up the story. Miss Gigout, does he have to be in our class? James pulled the chair off himself as the crayons rained down from the desk. His face burned deep red and he began to cry. He turned his back to the class, trying to pick up the mess hed caused, and I felt his shame. A special student. In the first hour and a half of our first day of school I saw clearly that James had the classic symptoms of Attention Deficit Hyperactivity Disorder (ADHD). He was inattentive, lacked concentration, stared into space, was impulsive and hyper. When James mother arrived to pick him up after school, we talked about his behavior. She informed me that James had indeed been diagnosed with ADHD but was not taking any type of medication because the family just couldnt afford it. I realized that something had to be done; I couldnt ignore his behavior, hope for the best and basically let this little boy fall through the cracks for the next nine months of school. A style versus a disorder. For the next few days I researched ADHD, trying to find a solution for our problem. I read books, searched the Internet, talked with the nurse at our school and to one of our special education teachers. No one seemed to really know how to teach a student with ADHD. They knew the symptoms and what type of medication to give, but really had no advice in the area of teaching. Richard Restak asserts in The New Brain (Rodale Books, 2003) that ADD/ADHD isnt so much a disorder as it is a cognitive style. With this in mind, through much trial  and error, I found my way through the next nine months. Along the way I came up with these suggestions to keep in mind when one has a James in the classroom: 1.Set a consistent daily schedule. The most important trick I found to work was keeping James on a regular schedule. By being consistent with our class schedule, James could regulate his day. He learned to watch the clock and tell just how much longer he had to sit still while I read. He knew how much time he had left to finish his assignment and what the clear consequences were if he did not finish. I found that by setting these clear consequences and rewards for his behavior, both good and bad, there were no miscommunications and he became responsible for his actions. Any time the schedule changed, I discussed the changes with James ahead of time so he was aware some things would be different that day. 2.Limit distractions around the students work area. James desk was slightly turned away from the rest of class to cut down on distractions. I didnt move his desk completely away from the other desks; I didnt want him to feel shut out or different. When it came time to work he could turn his desk away if he felt he was having trouble concentrating. On some days he had a hard time concentrating even if his desk was turned to the wall, but sitting on the floor close to my desk or in the classroom library would help him stay on task. I also had James keep only the necessary supplies at this desk; getting up for additional supplies gave him the opportunity to take a break, walk around and get rid of a little bit of energy. Sometimes James would stand while he worked at his desk; as long as the standing wasnt distracting to anyone around him, I let him do so. 3.Explain directions at least twice and have the child repeat them. I would tell the class the directions for an assignment, retell the directions to James one-on-one, then have him repeat the directions to me. By making sure James had three opportunities to get directions, he had a better chance of finishing the task. As the year progressed and projects got more detailed, I would explain two directions first; when those steps were complete we would discuss the rest of the task. I tried to keep the directions simple, limiting them to one or two tasks at a time. 4.Give silent cues that only you and the child know. Story time seemed to be the hardest task for James. He had to sit still on the carpet with his classmates and try to focus on what I was reading. I found that by asking James to sit close to me while I read I could give him a signal – a small tap on the shoulder or a little cough – to get his attention and bring him back to concentration. Even while working, these subtle cues would call him back without letting the rest of the class know I was talking to him. 5.Limit the amount of work given at one time. Instead of giving James a worksheet with 25 addition problems, I gave him five problems at a time. Hed finish those five, then take a break to get a drink of water or walk around, then come back for five more. Sometimes not all of the problems would be finished, but at least he worked without being frustrated and I didnt have to continually remind him to get busy. 6.And most importantly, be positive! With James it was important to focus on the effort, not the end-product. Praising him for completing part of a worksheet, even though some of the answers were wrong, gave him a sense of pride and made him try even harder. As we entered May, James had learned to read, add, subtract and even write paragraphs. He went from missing recess all week due to conduct to missing five minutes of it every few weeks for an occasional outburst. Eventually the students in my class noticed a change in James behavior and wanted to be friends with him. He was happier in school and more eager to learn. He no longer felt the embarrassment of being in trouble or not being able to control his actions. I did my best to embrace James cognitive style rather than fight it. I took the time to work in a partnership with James on his concentration instead of restricting him to what works for other children, which was far more rewarding for us both.

SPAM: The Unethical Email Phenomenon Essay -- Internet

SPAM: The Unethical Email Phenomenon It's what's for breakfast. As I wake from my deep sleep of twelve hours, I step out of bed and go about my daily summer routine. I wash my face and peruse through the fridge for something to eat; its noon, meaning the mail is in. I step out of the house to check the mailbox. I’ve always looked forward to receiving the mail, as most people do until they are old enough to pay the bills. I bring back the mail to the dining table as I commence to eat the leftover SPAM my mom cooked and hope for a magazine or catalog to look at. As I sift through the hoard of envelopes at my disposal, I sort them into their respective categories: â€Å"Bill, bill, junk mail, letter, junk mail, letter, catalog, bill, junk mail, magazine!† I toss out all the junk mail and keep the stuff I really am going to read: the sports catalog and car magazine. After finishing breakfast, I head back to my room and turn on my computer, log onto the internet and check my yahoo email inbox. As I log into my account, I notice the glowing red warning that my inbox is at 101% capacity. I receive 8 new emails, 5 of which are obvious junk mail, 2 mysterious emails addressed to my name, and another email which I was expecting from a teacher. I immediately delete the obvious SPAM which I have trained myself to notice right away after years of internet use, then spend time to open and view both mysterious emails which also turn out to be SPAM. After all that energy is spent, I am finally able read my teacher's important e-mail. Remembering that my inbox is blinking red, I delete the bulk mail folder that yahoo has graciously provided as a SPAM filter, which holds 94 new SPAM emails, then finally empty out my email trash.

Changing Role of Hr Management Essay

The Changing Role of Human Resources Management The ever-changing roles within human resources management (HRM), in response to trends, are from a dynamic environment and the importance of HRM. Every changing organization has a need for a HRM to respond and implement changes. The organizations driven by e-business and technology need to be ready to respond and adapt to the environmental changes and should focus on satisfying the company’s customer needs. In this role, the HRM contributes proactively to the development of global strategic plans and objectives. This essay will explain the changing roles in human resources management to the trends of: (a) globalization, (b) technology, (d) diversity, (e) e-business, and (f) ethics. Globalization The globalization of a business is the major challenge in human resources within the management of the business, new competitive aspects, and the cultural diversities are adding frequently (Gale Group, 1999). To reach the demands, the HRM is developing new business procedures and practices to adopt the shifting patterns of business. The human resources must deal with numerous challenges like maintaining proper coordination from the business activities in multiple locations around the globe. Human resources must prepare and have an understanding of the increase in global competition. The human resources departments are gaining awareness globally for the development of the human resources teams with activities dealing with the multicultural diversity. Technology The performance of HRM relies largely on the technological aspects. With the introduction and use of advanced technologies, the abilities and performances of the human resources are in need of required output. Businesses are incorporating advance technologies for meeting the demand of the consumers. This development has the human resources beginning to train continuously on the newer technologies in an effort to create processes, which are more effective. HRM is requiring changes in its practices to accommodate the advance computerized technologies and information systems (Frantzreb, 1998). All work done manually by the department must change to a more technical form to maintain and control the processes and data for a business to be more effective and productive. The technological skills within the human resources require coordination with the advance technology-based processes. Diversity The multicultural practices in business are making the environment within a business more diversified. In business environment today, a human resources professional come from multiple cultures and are working side-by-side in the same company meeting the same goals. For these professionals, it is paramount in maintaining a complete and thorough understanding of the morals, ethics, and values of the multiple cultures. The human resources professionals are developing innovative ways of managing the knowledge to deal with the diversity of the cultures. In addition, business environments that have diverse cultures are educating the HRM to perform the activities to the local consumer driven demands. Fast implementations in cultures are because of advancing technologies, which are causing the human resources to change its practices (Collins & Clark, 2003). E-Business In an effort to eliminate the work burden, businesses are transforming normal operations to the e-business technological form. Business in the electronic form is causing the HRM to transform and develop newer procedures and practices. The human resources of companies have to maintain new skills and change the understanding from the brick and mortar style of business to the more advanced technological business environment, which is in a computerized form. To advance the performance levels, the HRM is starting to incorporate training in information technology to the human resources professionals in an effort to maximize the adaptation to the rapid changes to the practices for the e-business model (Mitchell, 2001). The human resources professional is requiring the computer and Internet-based business technologies to follow the accounting and marketing practices. Ethics In addition to being competitive, business professionals must maintain an even balance with the organizations ethics (Vickers, 2005). The HRM must create a business environment that is suitable with the company’s ethics policies. The HRM must maintain the interests of the stakeholders to an equal level without any discrimination. The first priority must be to the consumers’ best interest. To accomplish and maintain a balance between maximizing profits and maintaining consumers’ satisfaction, the HRM must make the business’s practices in such a manner. Conclusion Human resources management must be a major section within the business’s environment, which must adapt its roles to accommodate the ever-changing trends of the global practices. The HRM roles must not change for only a single aspect, but simultaneously alters according to all the factors. The most important aspect is in globalization. Other aspects like technology, as with e-business, makes the need for the knowledge of professionals within the HRM to be more technologically advanced. The ethics and diversities in business demand the management to maintain the vision of its employees to an equal level.

Liberation War of Bangladesh Essay

Our liberation is the greatest achievement in our national life. The War of Liberation of Bangladesh took place in the history in 1971. We had been under Pakistani rule for twenty five years. The Pakistani rulers and their vested interest group began to treat East Pakistan as a colony gof West Pakistan. Therefore, under the leadership of Bangabandhu Sheikh Mujibur Rahman, a violent mass movement was launched against the autocrats of the West Pakistan. Subsequently, the Awami League won a landslide victory at the election of the National Assembly of Pakistan held in December 1970. Thus Bangabandhu acquired the right to form the government of Pakistan with his absolute majority in the parliament. Despite having absolute majority, Awami League could not ascend to power due to Yahia-Bhutto conspiracy. With the plea of discussion with Bangabandhu, President Yahia Khan began to collect arms and ammunitions from West Pakistan. Having taken all preparations, Yahia flew to Rawalpindi and signed the order for Bangalee massacre. On the black night of March 25, 1971, the Pak army got down the streets of Dhaka. Bangabandhu was arrested and taken to the prison of West Pakistan. In the mean time, Bangabandhu declared the independence of Bangladesh. The War of Liberation started and the Pakistani forces cracked down upon the innocent and armless people of Bangladesh. They continued to kill innocent people and intellectuals, torture innumerable women, burn houses, loot property and damage crops. One crore of people fled away and took shelter in India. In the meantime, new government was formed at Mujibnagar and people from all walks of life started to take part in the war obeying the call and order of Bangabandhu. As a result, the Mukti Bahini was organized and trained. They started counter attack on the Pakistani forces. During the Liberation War of Bangladesh, everyone was a freedom fighter and did his best to help the Mukti Bahini. Eventually the Mukti Bahini gained strength and efficiency and kept the occupation forces in extreme embarrassment. At one stage, the Mukti Bahini and the Indian forces formed a joint command and started severe attack on the enemy in every sector compelling them to surrender. On the 16th of December, 1971 they surrendered their arms to the Joint Command at a ceremony in Dhaka. Thus after long nine months of massacre, the War of Liberation came to an end and Bangladesh achieved freedom from the barbarous Pakistanis. In fact, it was the triumph of justice over tyranny.

The Great Migration essays

The Great Migration essays During the early decades of the twentieth century, African Americans left the South in growing numbers, migrating North, with hopes of leaving a life behind that was dictated by racism, Jim Crow law, disenfranchisement, and violence based on hatred of black skin. With dreams of new opportunities for economic self-sufficiency, political participation, integration and freedom from racial violence, African Americans were soon to be met with resistance from Northern whites and middle-class blacks who perceived the migrants as representing a black mass who would change the face of the northern urban landscape forever. The immediate result of the influx of African Americans into urban areas of the North was the eruption of violence during the 1919 race riots, which tore the Chicago apart. Headlines proclaiming a sense of horror, disdain and humor in white-oriented newspapers provided evidence of white response to the arrival of migrating African Americans into Northern cities that had remained predominantly white. There was a growing tension that suggested that there was a need for whites to engage in efforts to control African Americans as they moved into the North and to engage in violence against them out of perceived necessity due to their intrusive presence which stirred up feelings of fear and insecurity on the part of whites. In Chicago, which gained over fifty thousand migrants between 1910 and 1920, fear was brimming and evident on the part of whites. While African Americans did not experience massive benefits upon their arrival in the city, they gained some sense of greater dignity and pride as they began attempting to settle into the urban area. However, numerous obstacles were present and intended to prevent African Americans from gaining full access to benefits enjoyed by whites. In 1874, Illinois had legally abolished school segregation and desegregated pub...

History of Portugal - Overview

History of Portugal - Overview Location of Portugal Portugal is located in the far west of Europe, on the Iberian Peninsular. It is bounded by Spain to the north and east, and the Atlantic Ocean to the south and west. Historical Summary of Portugal The country of Portugal emerged in the tenth century during the Christian reconquest of the Iberian Peninsula: first as a region under the control of the Counts of Portugal and then, in the mid-twelfth century, as a kingdom under King Afonso I. The throne then went through a turbulent time, with several rebellions. During the fifteenth and sixteenth centuries overseas exploration and conquest in Africa, South America and India won the nation a rich empire. In 1580 a succession crisis led to a successful invasion by the King of Spain and Spanish rule, beginning an era known to opponents as the Spanish Captivity, but a successful rebellion in 1640 led to independence once more. Portugal fought alongside Britain in the Napoleonic Wars, whose political fallout led to a son of the King of Portugal becoming Emperor of Brazil; a decline in imperial power followed. The nineteenth century saw civil war, before a Republic was declared in 1910. However, in 1926 a military coup led to generals ruling until 1933, when a Professor called Salazar took over, ruling in an authoritarian manner. His retirement through illness was followed a few years later by a further coup, the declaration of the Third Republic and independence for African colonies. Key People from the History of Portugal Afonso HenriqueThe son of the Count of Portugal, Afonso Henrique was the rallying point for Portuguese nobles who feared losing their power to rival Galicians. Afonso won either a battle or a tournament and successfully expelled his mother, who was styled as Queen, and by 1140 was calling himself King of Portugal. He worked to establish his position, and by 1179 had persuaded the Pope to recognise him as king.Dom DinisNicknamed the farmer, Dinis is often the most highly regarded of the Burgundian dynasty, for he began the creation of a formal navy, founded the first university in Lisbon, promoted culture, founded one of the first insurance institutions for merchants and broadened trade. However, tensions grew among his nobles and he lost the Battle of Santarà ©m to his son, who took the crown as King Afonso IV.Antà ³nio SalazarA Professor of Political Economy, Salazar was invited in 1928 by Portugal’s military dictatorship to join the government and resolve a financial crisi s. In 1933 he was promoted to Prime Minister, and he ruled – if not as a dictator (though an argument can be made that he was), then certainly as a repressive, anti-parliamentary authoritarian, until illness forced him to retire in 1974.

Interpersonal Communication Speech or Presentation

Interpersonal Communication - Speech or Presentation Example Interpersonal communication includes sending and receiving messages between two or more individuals. This form of communication involves all aspects of communication such as listening, asserting, persuading and non-verbal communication among others. In addition, the individuals communicate on different interpersonal levels depending on the individuals they are communicating with (DeVito 5). This asserts that the interpersonal communication skills involved when an individual is communicating with a family member is different when the same individual is communicating with a friend. In successful interpersonal communication, the senders and recipients of messages are supposed to understand the messages, their meanings and implications. In addition, interpersonal thinking plays a crucial role in establishing concentration and certain problem solving skills (DeVito 8). Interpersonal communication is regarded as the most private form of communication. Some of the examples of interpersonal communication include day dreams, talking to oneself and comprehending a book article. In fact, this information occurs in an informal setting. The observer can also use cues of posture, dressing or even facial expressions to make an impression on the role of the other individual. This is because individuals have the ability to send and receive messages in a non-verbal form. In the movie â€Å"You’ve Got Mail†, Meg Ryan fell in love with Tom Hanks through the internet. This was after a series of disclosures that were made using the email. In this case, the two characters forge a relationship just like individuals who are having a face to face interaction. These characters got attracted to each other and eventually fell in love. These individuals were attracted to daily conversations in the cyberspace. However, the email is continually becoming the playground, birthplace and graveyard for several personal relationships (DeVito 9). There are several elements of interpers onal communication. These elements include the communicators, the message, feedback, noise, communication channel and the context. Based on the movie, the two-way communication process between Meg Ryan and Tom Hanks was an interactive process. They used the email as a channel to convey their messages. The context of the message entails the love affair between the two individuals. In this case, there are several forms of noise including the use of complicated jargon, inattention, disinterest, errors, cultural differences and inappropriate body language (DeVito 12). As stated in the communication theory, noise has a highly significant role in interpersonal communication. The interpersonal communication in the movie is a two-way communication which involves two parties. In this two-way communication, the sender of the message is receptive to feedback. The one-way communication is difficult and time-consuming.
