Phosphorus Essays - Chemistry, Functional Groups, Phosphorus

Phosphorus The element that is featured in this report is phosphorus. Phosphorus is a chemical element that human beings, animals, and plants need for normal growth. The main use of phosphorus is fertilizer. It was difficult to find a lot of different information on this element. Description Phosphorus is a nonmetallic chemical element that can exist in several different forms. The chemical symbol for phosphorus is P, its atomic number is 15, and its atomic weight is 30.975. Phosphorus was first prepared by the German alchemist Hennig Brandt in 1669; in the course of his search for the philosopher's stone he obtained from a residue of evaporated urine a white solid that glowed in the dark and ignited spontaneously in the air. The name phosphorus is Greek for "light-bringing". The name at that time was used for any substance that glows of itself, and was eventually given to this element. Phosphorus does not occur in elemental form in nature; it is found most commonly in apatite minerals such as fluorapatite. Their are at least ten forms of the element that are known, occurring within red, white, and black phosphorus categories or as mixtures of them. White phosphorus consists of molecular P(4) and can exist in an alpha form, which is stable at room temperature, and a beta form, stable below -78 deg C. White phosphorus is a waxlike substance, very toxic and extremely flammable. When it is exposed to air in the dark, it emits a greenish light and gives off white fumes. It can ignite spontaneously. Red phosphorus is a more stable form than white. Red phosphorus is a brownish-red powder and it can be obtained by heating white phosphorus to 250 deg C in a closed vessel or exposing white phosphorus to sunlight Red phosphorus is often considered a mixture of white and black phosphorus. It neither phosphoresces nor spontaneously burns in air. Red phosphorus should be handled carefully at certain temperatures because it can change to white phosphorus. Upon heating to temperatures near 300 deg C for several days, red phosphorus is converted to black phosphorus. Black phosphorus is a much less common form. It is flaky, like graphite, and has some metallic properties. It is the least reactive of the forms of phosphorus. Physical Properties Some of the physical properties of phosphorus are its various colors as listed above. The most common colors are white, red, and black. In the white form it is a waxlike substance. In the red form of phosphorus it is a brownish-red powder and the black form resembles the mineral granite and is flaky. Chemical Properties A chemical property found in phosphorus is its flammability. Also, it glows in the dark when exposed to air. Phosphorus can change forms by the changing of temperature. Phosphorus is also very toxic. The chemical properties change depending on what form of phosphorus is used. Uses of the Element Phosphorus is used for many different things. White phosphorus is used in incendiary and napalm bombs. It is used in the explosive part of the bombs. Phosphorus is one of the most important substances for life along with water, carbon, nitrogen, oxygen, and sulfur. The principal components of organic matter are carbon, hydrogen, and oxygen. Nitrogen, phosphorus, and sulfur are important because they interact with the carbon-hydrogen-oxygen matrix. These substances are components of natural cycles that have geological as well as biological components. Another use for phosphorus is the match. The first friction matches were tipped with mixtures that included the incendiary chemical white phosphorus. They were produced in the 1830s. They would ignite when struck against almost any rough surface. For workers in match factories, however, the white phosphorus proved a deadly poison; the incidence of "phossy jaw," a bone malady caused by the chemical, was among the earliest of recognized occupational diseases. The safety match, developed in 1855, could be ignited only by striking it on a surface containing red phosphorus. Phosphorus remained a hazard in "strike anywhere" matches, however, until the development in 1911 of phosphorus sesquisulfide, a nonpoisonous chemical. The blast furnace iron also contains a small but significant amount of phosphorus. In the steel making process most of the phosphorus must be reduced. The phosphorus level is very high in milk, meats, many vegetables, and fruits such as bananas. It is very important for the human body to receive a certain amount of phosphorus because it is essential to the building of bone. Another function of phosphorus in the human body is that it is needed in intermediary metabolism. 10 Compounds of the

Ansel Adams - Essay Example He got his distinct mark in his nose when he was thrown to the ground during the aftershock of earthquake and fire in 1906, when he was just four years old (Turnage, n.d.). According to Turnage (n.d.), he was born in a very conservative social and emotional environment being an only child of elderly parents. It was in 1907 when the family’s fortune collapsed that Adams’s father spent the whole time to regain their lost fortune (Turnage, n.d.). He loved music and started to play the piano which inspired and crafted his visual artistry. He gained an appreciation of nature living his childhood at the Golden Gate which is his primary foundation photography (www.sierraclub.org, History: Ansel Adams). He was once an unpromising and rebellious student which resulted to his removal from school (Szarwkowski, 2010). According to Szarkowski (2010), he was a gifted pianist thus made him become determined and ambitious musician. In was in 1916 when he got his first camera that he de monstrated his talent in photography (Szarkowski, 2010). It was in the year 1927 when he took his first High Trip of the Siera Club and finished his first fully dreamed of photograph, Monolith, the Face of Dome (Turnage, n.d.). This year became very important because he met San Francisco’s patron of arts and artists and insurance tycoon, Albert Bended, whose companionship, encouragement and polite financial support changed Adams’s life (Turnage, n.d.). It was Bended who took charge of the preparation and publication of Adams’s first portfolio, the Parmelian Prints of the High Sierras (Turnage, n.d.). Bender was the main influence who transformed a journeyman pianist to a creative photographer (Turnage, n.d.). Adams’s joined annual Sierra Club outing and became their official photographer. His role in the club grew quickly which in turn the club developed into a very important factor to his success in photography (www.sierraclub.org, History: Ansel Adams). His membership in the club developed his political involvement thus suggesting proposals for improving parks and wilderness (www.sierraclub.org, History: Ansel Adams). The club soon became an influential national organization that fought for the creation of national parks and protection of environment (www.sierraclub.org, History: Ansel Adams). He became prominent in photographic community in 1935 when he was working and contributing technical articles to a popular photography press (Szarkowski, 2010). In 1936, his worked was renowned by Alfred Steiglitz and he further used his position in the field to boost approval of photography as fine art since then (Szarkowski, 2010). President Jimmy Carter awarded the Presidential Medal of Freedom to Adams in 1980 as recognition of his work as environmentalist and photographer (Szarkowski, 2010). Although he worked basically in the photographic print, he also got involved and became a motivator of the photomechanical reproduction (Szarkowski , 2010). He persistently explored the technical possibilities of photography in the 1940s (Szarkowski, 2010). According to Szarkowski (2010), Adams also got really busy of the â€Å"zone system† which â€Å"rationalized the relationship among exposure, development, and resulting densities in the photograph

Three Favorite Words in English Essay Example | Topics and Well Written Essays - 250 words

Three Favorite Words in English - Essay Example It is vital that the people who fall in love, should respect each other especially because no matter how people love each other, there are always individual differences that should be bridged. Therefore, it is important for two people to respect each other’s beliefs, personalities and cultures so that conflicts will be minimized and the possibility of losing the passion will diminish. Trust is also very important in a relationship bound by love because it serves as a glue that holds two different people together who do different things. The modern world now demands both male and female to contribute to the economic status of the nation and is now a challenge to modern lovers because they have to be away from each other most of the hours of the day and probably even demand more time from others. This situation exposes lovers to temptations that may be difficult to fight however, when one partner is well aware of how much trust the other has for him, and that trust is respected and valued, love can remain pure between

The Published Financial Statement Accounting Essay

The Published Financial Statement Accounting Essay Annual report and accounts consists of different elements. A financial statement contains the financial information which is communicated to various users depending on their needs. The users can be internal or external users. The importance of this information varies, depending on the needs of specific users but according to the framework, the publication of financial information serves to reflect and to provide a clear image of the financial situation and performance of the entity which will help them to make a financial decision. Thomas and Marie (2012, 55). Users need financial information to assess the way the company uses its liquidity to fund its operations and investment, to be informed about its financial position and the nature of its resources for daily transactions, to estimate or predict the circumstances that may affect them, to be informed about the extent to which the company follows the laws and regulations. Usually the performance information is represented on the in come statement, the financial situation is represented on the balance sheet, and the information about changes in financial position is supplied in the notes to financial statements. Financial statements are the principal means of communicating financial information to various users. The framework defines seven essential users (Jill and Roger, 2007) but in contrast, Peter and Eddie (2002p 3) state that there are internal and external users who already have a relationship with the firm in economic terms or those who are interested in a future relationship. Starting with managers, Petter and Eddie (2002.3) noted that managers need information to assist them to make the decision and adopt and strategy of planning for the future. Furthermore, the manager who has been put in charge of presenting financial statements also needs this information to be sure that the management style, strategy and planning adopted are beneficial to the financial performance of the company. The conceptual framework states that the employees are principally interested in the type of information which permits them of having a clear idea about the stability and the performance of the company that they work for (Thomas and Ward,56 2012). Employees need information in order to ensure the stability of their jobs in the future, and to measure their ability to determine if there is a chance of getting a higher pay or promotion, and other benefits. The Investors need information about management policy, performance, stability and financial position of the company as well as to assess the risk and benefits provided by the investment in order to make a decision. Also, they need information to help them choose the proper time for transactions like buying and selling. Thomas and Ward (2012:56) Lenders are always taking risks which is why they choose the contract with lowest risk the framework noted that they are interested in information about performance and economic stability of the company, and also the information about the situation of liquidity available in the present and the future, in order to ensure whether the borrower is able to meet the deadlines for the payment of their loans and the interest. (Thomas and Ward, 2012:57). Regarding suppliers and other creditors, Thomas and Maries said that giving a loan and outputting goods without immediate payment is the same. This is the reason, they will be interested in the information that will help them at the beginning to decide whether to engage with company or not, and also to study the duration and the amount of credit to offer. According to the framework, suppliers and other creditors are interested in information that enable them to know whether they will be repaid at due date. Yet Suppliers and others creditors are interested in engaging with the enterprise for a shorter period compared to lenders who are concerned about liquidity position and the supplier seeks to know if there is a growth within the company and compare it with these production capacities. Jill and Roger (200741) states that the customers are interested in the information that enable them to evaluate the performance and ability of the company to continue its business and to know their capacity to meet the requirements of quality, the quantity and time to provide goods and services depending on customer needs. Governments and their agencies are composed by the tax authorities, financial and organization like central bank that has authority of control and regulations. Principally, the information is used as basis for calculating dues and taxes that the company has to pay. It has noted that the government and their agencies are interested in information about profitability and how it is distributed, with the aim of determining the tax policy, as they need information on the conduct of activities of entities to adjust them. (Thomas and Ward, 582012) The public is also interested in information about the performance of the company in order to define the level at which the company is progressing and its impact on economic development and social environment. To ensure that the information is useful to users for decision making, four qualitative characteristics need to be present in the information. Understandability the user must understand the information directly but should have basic knowledge of accounting and the economy. Relevance information must meet the needs of users in order for them to make decisions and enable them to compare the events of different periods. Reliability information must be reliable to give a real image of transactions and other operations. Comparability the information has to be available for comparison over time to determine the situation and the economic performance. (Jill and Hussey, 422007) It is true that the financial information addresses different user groups under standard characteristics, but it still has limitations on the usefulness of the information. The financial statement is based on historical costs. That is to say it is only monetary operations but the declaration is not correct. Also, with regards to the intangible assets there is no possibility of measuring the values of all of them in the sector of accounting. For instance, human resources are also ignored in most financial statements, and the brand value of the company is not on the statements either. Inflation is not included in the present value and all the information are based on estimates, so there is no real value on which the user can rely on. The financial statement does not take into consideration any anticipated financial condition that can happen in the industry and market which might affect the performance of the company and the decision taken by the different users of the financial statement which contains only financial information and ignores the non-financial information which is not sufficient for certain users as the case of public and employees. In contrast, investors are more concerned than other users by information presented in the financial statement. To conclude, the company is obliged to communicate the information under financial quality standards that are useful to different users, which are a total of eight. They are; managers, investors, customers, suppliers and other creditors, employees, lenders, government, and the general public. The objective of this information is to reflect the performance, position and stability of the company for the user to make a good decision. Despite the quality and control, the rest information is still not reliable and useful for certain users to make a decision.

Leadership: The MBTI Assessment

The Myers-Briggs Type Indicator (MBTI) is a personality assessment that helps to assess one's psychological preferences based on a psychometric questionnaire. These preferences were extracted from the typological theories proposed by Carl Gustav Jung writings in his book ‘Psychological Types'. The MBTI focuses on normal populations and emphasizes the value of naturally occurring differences. [1] Also recognized commonly as a behavioral assessment tool, the MBTI uses a combination of 4 letters and each represent a clearly defined attribute. Altogether, the MBTI test consists of 16 different personality types that will describe one’s personality in alleged detail. The MBTI test has reviewed that I am type ENTJ which covers aspects of being extraverted, intuitive, thinking and judging altogether but in different extents. According to Dr. David Keirsey, he states that a person with type ENTJ is recognized as a ‘Fieldmarshal’ or basically someone who is a natural born leader as agreed by Joe Butt in his article on ENTJ. He adds that this attribute of Fieldmarshals are a rare breed that are natural at taking the lead, are structural organizers and have an act on devising contingency plans. These collectively form characteristics of a leader who will be decisive and are visionary in setting goals and direction. Having these traits of a leader, Fieldmarshals are expected to take up roles of higher responsibility and will usually take pleasure in them. However their strong devotion to their work may sometimes be a hindrance to their social lifestyles. Another prevalent characteristic of a Fieldmarshal is the tendency to emphasize on efficiency and are usually intolerant of prodigality. [5 &6] I have to admit that while reading the results and review of my personality type; it felt like a strong confirmation of how I evaluate myself. Most of the traits specified were indeed very accurate such that I am a natural leader. I have come to realize that not only do I have the tendency to lead others but I also enjoy taking responsibility and I feel more comfortable in planning ahead rather than doing things spontaneously. Being extraverted is also a spot on because I am that person who would walk across the room to get to know someone new and am not afraid to express my thoughts publicly. Looking at the basis of how the personality results were generated, I still do not comprehend how I only scored 1 in the ‘Thinking’ category as I usually make decisions based on facts and logic. Apart from the MBTI test, the Dominance Influence Steadiness Conscientiousness (DISC) test is also another credible assessment tool that provides an effective feedback and rational to help one identify his/her personal behavior and strengths, thus increasing self-awareness. The DISC assessment is a shorter test as compared to the MBTI and yet yields more specific results from over 19,000 personalized responses and 384 separate behavioral descriptions. [3&4] One other assessment would be the Herrmann Brain Dominance Instrument (HBDI) which measures thinking preferences in people. This model functions very similar to the others by incorporating cognitive style measurement. HBDI in short, adapts a concept of determining one’s dominant thinking style based on analytical, sequential, interpersonal and imaginative aspects. [7&4] Paul D. Tieger and Barbara Barron-Tieger, who are both recognized experts in personality type and career development, agreed that the MBTI can serve as career counselors to guide and find jobs that are best suited for a person. [8] However the Army Research Institute commissioned a review on this and argued that there is no evidence for the utility of the test and further claimed that the classification scheme is limited and may be an example of stereotyping personalities. Other questions have been raised in David Pittenger’s report of how the MBTI instrument comes up short for what it purports to measure. Some of which are mainly concerns on the reliability and validity of the results. [9] Considering all that, the objective of the MBTI is somewhat achieved when it helps to facilitate self-awareness which can then lead to self- improvement. With critical feedback provided, one will be able to realize their potential essentially natural leaders, and also to reaffirm one’s focus on their strengths. As discussed, discretion may be necessary to protect one against undue reliance upon the MBTI especially in career choices.
