Chemical Decomposition Reaction

Chemical Decomposition Reaction A chemical decomposition reaction or analysis reaction is one of the most common types of chemical reactions. In a decomposition reaction a compound is broken into smaller chemical species.AB → A B In some cases, the reactant breaks into its component elements, but a decomposition may involve breakdown into any smaller molecules. The process may occur in a single step or multiple ones. Because chemical bonds are broken, a decomposition reaction requires the addition of energy to begin. Usually the energy is supplied as heat, but sometimes simply a mechanical bump, electric shock, radiation, or change in humidity or acidity initiates the process. The  reactions may be classified on this basis as thermal decomposition reactions, electrolytic decomposition reactions, and catalytic reactions. A decomposition is the opposite or reverse process of a synthesis reaction. Decomposition Reaction Examples The electrolysis of water into oxygen and hydrogen gas is an example of a decomposition reaction:2 H2O → 2 H2 O2 Another example is the decomposition of potassium chloride into potassium and chlorine gas. 2 KCl(s) → 2 K(s) Cl2(g) Uses of Decomposition Reactions Decomposition reactions are also called analysis reactions because they are extremely valuable in analytical techniques. Examples include mass spectrometry, gravimetric analysis, and thermogravimetric analysis.

The Post Office is Kitty-corner to the Court House

The Post Office is Kitty-corner to the Court House The Post Office is Kitty-corner to the Court House The Post Office is Kitty-corner to the Court House By Maeve Maddox Cassandra Marx writes: In the last few weeks, I have seen or heard numerous references to something being catty-cornered, katty-cornered, and kitty-cornered to something else. Would you please tell me what the correct usage/spelling is? Although I have included this expression in a previous post on cat words, I think it deserves a post of its own. Heres what I had to say the first time around: Catty-corner is a directional word, meaning that something is diagonally across from something else. The word started out as cater-corner. Cater is an English dialect word meaning â€Å"to set or move diagonally.† When the word cater with its meaning of to set or move diagonally dropped out of the language, folk etymology got busy and now we have all kinds of â€Å"cat† variants for this concept: catty-cornered†¨ kitty-corner†¨ kitty-cornered†¨ catty-corner†¨ cat-a-corner kitty-corner†¨ kit-a-corner This time I have my brand-new copy of Brewers Dictionary of Phrase Fable (17th edtion) to consult. This is what I find under the entry cater-cornered: Cater-cornered. Placed diagonally, as of a badly parked car in a parking space. Cater is an old word for the four dots on dice, which form diagonals, from French quatre, four. Other spellings of the term are catty-cornered and kitty-cornered, as if somehow to do with cats. Apparently the dialect word with the meaning to set or move diagonally, derived from quatre. As for the correct usage/spelling, the usage seems to be universal as to meaning. Something that is catty-cornered to something else is diagonally opposite. Until some authority decrees otherwise, I suppose that spelling and pronunciation are a matter of local usage. I grew up with kitty-corner. Want to improve your English in five minutes a day? Get a subscription and start receiving our writing tips and exercises daily! Keep learning!

Personal Educational Philosophy Essay Example | Topics and Well Written Essays - 750 words

Personal Educational Philosophy - Essay Example Vicarious reinforcement is indirect reinforcement and does not come from without. It comes from the person himself so that it is also called self-reinforcement. Imitation and modeling as the terms suggest simple mean that a person learns what he sees. Models particularly are imitated. The model could be a parent, a teacher, peer, basketball star or even I whose behavior is imitated. My impact as a teacher being a role model in the classroom cannot be overemphasized. This is true in all aspects of learning that range from mechanical speech learning to the more complex learning of values. No matter how good I am on the theories of good speech if I do not talk well, the learners may not learn to talk correctly. In like manner, a good discourse on moral values like honesty will not do any good if the learners are witnesses of dishonesty in the classroom and in bigger society. Most observational learning studies have been focused on films and television shows. In fact, the researches of Bandura and Walters on observational learning included exposures of the experimental groups to films. Aside from this, I also adhere to Bandura's different models. Environmental model refers to the observations made of sexual reproduction among domestic animals like dogs, cats, chickens, and other including plants like vegetables and fruits. Parental instruction model ... Also included in this category are the peer groups through teasing, conversation, cursing, etc. Cultural model refers to the use of folk tales in order to illustrate the concept of size, the normative and "don't's" in verbal reference to sex; the use of language to identify basic elements of social organizations. The foregoing results reveal the modeling role of parents and peers which become especially important within the context of parents and teachers as authorities. In a society where children are left more and more with their peers, the latter's modeling could lead to more imitative sex-related and other forms of behaviors. In social or observational learning, Bandura emphasized four subprocesses; namely, attention, retention, motoric reproduction, and reinforcement. For any observational learning to occur, I believe that the model stimulus must be attended to. What has been observed must be retained if the model's behavior is to exert influence even after a period of time. Imitation follows only if the individual had motoric reproduction or actually imitated the behavior of the model. The last, reinforcement is internal rather than external. In this Bandura states that reinforcement is a motivational factor rather than a strengthening factor. Social learning theory seemingly explains many of our behaviors. The way we talk and walk - our gestures - many have been learned from the models that we have been exposed to. No wonder, children talk like their parents and resemble those of their parents. Friends, too, behave similarly. The social learning theory points out the crucial influence of television, radio, movies, and other forms of mass media which are fertile sources of models for

Employment Law - Essay Example He complains of unfair elimination of his unused vacation. There was no proper written notice of termination of Tomas employment. The company provided a two-week termination payment in lieu of notice. Tomas promotion to a data entry manager made him work for about 55 hours in a week. This made him eligible for overtime because he worked for more than 44 hours in a week. This is because he was promoted a month after his overtime work that is within three months as stated in the Employment Standards Act of 2000. In Zsoldos v. MMMC Inc. Architects, 2005 CanLII, it the plaintiff signed an agreement with the defendant that was legally binding to both parties. Tomas needs compensation for the time off not taken, in addition to the hours he worked during public holidays. He should get time off for the holidays he worked in addition to the three weeks off as stated in the Employment Standards Act. It was not appropriate to eliminate the unused vacation because it could only be legally binding if there was a proper agreement signed in writing and not an oral agreement. This should be effective within seven days of employment termination. The withdrawal of the health benefits was inappropriate because Tomas was still an employee before the major clients seized to do business with Crowne Company. The company should provide the health benefits for the period stated in the contract agreement with the employee. In case of termination of the health benefits, there must be a written notice to the employee. Tomas termination of employment was inappropriate, as his employment with Crown Company lasted for more than three months. In addition, the employer did not give him a proper written notice informing him of the termination of his employment or a pay for the termination. The termination pay in lieu of notice was inappropriate. This is because in case of employment termination the pay in lieu of notice is effective within seven

Examining Visual Identity of logo example Essay Example for Free

Examining Visual Identity of logo example Essay Today’s business world is moving at a fast pace and is ever changing, strong corporate identity and corporate image is increasingly necessary to any organization to succeed by embracing this dynamism (Stevenson, Christensen, 2001, PP. 231). Our society is moving at a fast rate than ever witnessed on the globe and many businesses places the human capital and consumer at the center of success strategy. Therefore, to achieve this success effect to the business, effective visual communication through the use of static and dynamic graphics; typography, color, and symbols are used to convey facts, concepts and emotions to the consumers and other stakeholders. This make up systematic graphic design that is information oriented, which helps customer base understand complex information and identify the company’s products that can be translated to profits (Stevenson, Christensen, 2001, PP. 290). In this regard, the logo example in form of an apple fruit is to Apple Computer Inc. the logo is such a familiar one, since it is on the digital and music products that I have interacted with. These products are Cinema Display, iPod, iPhone, Apple TV which are dominant to the young persons, while other products where the logo is displayed are Apple software, Mac, Mac OS X, Mac OS X Server, iLife, iWork and AirPort. Apart from the products of the Apple Inc. company, the logo is placed on entrance of organization’s corporate headquarters in the middle of Silicon Valley, at 1 Infinite Loop, Cupertino, California. Since it is founding in early 1976, Apple computer Inc. has revolutionized personal computing. Additionally, Apple has introduced amazing and wonderful products that have gone beyond technological boundaries. Thorough its attributing innovativeness in computer brands, Apple has become one of the world’s major computer brands in line with IBM, Microsoft, HP and Canon. Beneath Apple excellent brand performance and recognition globally, lies a powerful corporate identity facilitated by its well designed and unique logo. Apple logo is unique, in such a way that it does not bear any writings as many logos are and uses a bitten out apple fruit on the right side instead of a full fruit (Thomas, 2005). Yet, the Apple logo is one of the most recognized corporate symbols in the world of computer and digital business. Over the years since invention of the first logo in early 1976, Apple logo has undergone a revolution to capture the market corporate identity needs. Wayne and Jobs designed first Apple logo that depicted a graphic design of Isaac Newton sitting under an apple tree with words inscribed stating that â€Å"Newton a mind forever voyaging through strange seas of thought† with ‘Apple Computer Co’ (table1. figure 1). This first logo to be used by Apple company, was designed by artistic skills of human person through hand as computers that are dominantly used in our present days were not yet invented. However, the company logo was later changed in late 1976 by designer Rob Janoff of the Regis McKenna Agency designed an iconic logo of an apple with the bite out on right side and with rainbow colors; simply rainbow apple (table1. figure 2). This design greatly relied on the attribute and commemoration to Isaac Newtons discoveries of the gravity (the apple), and the separation of light by prisms (the colors) in scientific technological world (Thomas, 2005, p. 225). The rainbow logo apple was used up to 1998, when the logo appeared in many bright colors; whereby the logo example presented in this case with aqua color scheme was famous among all brightly colored logos of Apple Inc. (table1. figure 3). This aqua color scheme logo was used up to the year 2005, when Apple Inc. discontinued the use of bright colors (Thomas, 2005, p. 204). At present the logo in use have white and raw-aluminum color schemes (table1. figure 4) that result to silvery chrome finish that fit ideally. After revamping the Apple Inc. logo design, the logo freshens up the icon and is consistent with the design scheme. Therefore, making the Apple logo acceptable and endorsed not only by me as a consumer of Apple music products, but also the consumer base and critics world wide. Ideally, the logo design of Apple computer Inc. fit with the services and products it offers to the digital market. This is in the sense that, iconic logo of an apple with the bite out on right side is linked by many visual communication scholars to mathematician Alan Turning who was the father of modern computer who committed suicide by biting into cyanide laced apple. Most significantly the bite is projection and indication of byte vs. bite (Thomas, 2005, p. 304). Furthermore, a rainbow colored Apple logo was used to advertise the color capability of the Apple II computer and the product ‘Macintosh’ refers to a particular variety of an apple. Indeed, the firm is one of a few success stories in the corporate world with Market capital of US$86.3 billion, Revenue of US$32. 48 billion, Operating income US$6. 28 billion , Net income US$4. 83 billion with 14. 88% profit margin and a capacity of 28,000 Employees as indicated by a quarterly financial rep[ort of year 2008.

Life Changing Ideas in Harper Lees To Kill a Mockingbird :: essays research papers

Would you read a book that could change the way people lived their lives, but was against what people thought? How would you feel if you were the one writing the book? Would you go against the grain just to get your point across? Well Harper Lee did. She wrote To Kill A Mockingbird, to get a point across and in doing so she changed the way people think about everyday life. Nelle Harper Lee studied law for a short time, and then in 1961 the book To Kill A Mockingbird was published. She grew up in the small town of Monroeville, Alabama. Although she never said all her life experiences were incorporated into the book. By doing so she based her opinion through the thoughts and words of a young girl in the novel, known as Scout. Scout also grows up in a small town in the book, called Maycomb. In these small towns during the time in which the book was written, the white people of the community were put above all others. The blacks of the time were looked down upon, and considered the lowest of them all. In Maycomb this was no exception such is the case when the town, ?would go along with them on the assumption-the evil assumption-that all Negroes lie, that all Negroes are basically immoral beings, that all Negro men are not to be trusted (217) Also in such small towns everybody knows everyone, and because of such tight quarters all others a re branded as outsiders, and are distant from the community, which leads people to ask, ?If there's just one kind of folks, why can't they get along with each other? If they're all alike, why do they go out of their way to despise each other(240) Being involved or talking with these ?outsiders? was dishonorable. By writing the book Harper Lee did just that and went against what society is saying. In the book she speaks of being the outsider, rape, prejudice, and violence, even through talk about these things is shameful, she wanted to get her point across. She wanted people to know that ?it's a sin to kill a mockingbird`Mockingbirds don't do one thing but make music for us to enjoy.

How Far Should a State Have a Right to Monitor the Actions of People Within Its Borders?

The state should monitor the actions of people within its borders if such actions pose a threat to the national security. A nation's security is of an utmost importance to a country as it ensures the survivability of a country. It is with this reason that the government should have a right to monitor the actions of the people within its borders. This refers to individuals who engage in terrorist activities with the aim of conducting terrorist attacks in the country to instill fear in others. E. g. In Singapore, the government monitored the actions of Mas Selamat when the police received tip off of his plan to bomb the Singapore Changi Airport in 2002, where he was eventually arrested. The state should have a right to monitor the actions of the people within its borders, especially during stressful times such as war; as long as its monitoring does not result in the violation of human rights. Possessing the highest power, the state has jurisdiction in virtually all areas that society h as to deal with. Hence, it does have the right to monitor the actions of people. In times of war, famine, disease and violent acts will arise. In such times, the general public is unable to control and detain the situation, thus requiring the intervention of a higher power. For example, the state should have the right to implement a curfew during a war. This helps keep the people safe and reduces the chance of a violent protest or riot that may result in more deaths. Eg: During the 2010 clash between the red shirts and the yellow shirts in Thailand, the state intervened and imposed a curfew to monitor the actions of the Thais. This action has prevented more deaths and kept the people safe. Thus, the state should intervene in times of war to help control the situation. Government should not have the right to monitor actions of people when it comes to choosing one's life partner. Individuals should be given the freedom to decide with whom they would want to spend the rest of their lives with. If the government were to interfere in this issue, it would go against the basic human rights of freedom of choice. However, the state should not intervene when it violates human rights. The purpose of the state monitoring is to benefit the people; however when the state crosses the line and invades the privacy of people, this right should be revoked. Eg: the Central Intelligence Agency (CIA) in America has the authority to monitor anyone without the person legally consenting to it. This has resulted in the unhappiness of Americans and resulting in Americans losing faith in their legal system. Thus, the state should have a right to monitor the actions of people when in dire situations such as war but not at the expense of the privacy of people.
