Reactivity of Mg and Ca Essay Example for Free

Reactivity of Mg and Ca Essay Introduction The aim of this practical is to observe the difference in the reactivity between Mg and Ca when hot and cold water is added. Hypothesis We think they will react in some kind of form. Variables The independent variable was the temperature of the water and also the quantity of metal use in the experiment and the dependent variable was the reaction. Equipment * Mg (s) * Ca (s) * Phenolphthalein * Beaker * Cold and hot water * Sandpaper * Test tubes with rack Procedure 1. The Magnesium was cleaned with sandpaper. 2. Two pieces of magnesium was put into two test tubes and two pieces of calcium was put into two test tubes. 3. Cold water was added into two test tubes one with calcium one with magnesium. 4. Two droplets of phenolphalein were added in each of the test tubes filled with cold water to observe the change in ph. 5. Water was heated over a Benson burner and poured into the two test tubes without water while observing the reactions. 6. Two droplets of phenolphalein were added in each of the test tubes filled with cold water to observe the change in ph. Observation Relative reactivity of Cold water Hot water Mg There was a minimum reaction. Fig. 1 There is a bigger reaction than with the cold water. Fig. 2 Ca The temperature of the water increases right away. Before we dropped the phenolphthalein the solution was white, fig.3, but after adding the phenolphthalein it turned pink, fig.4, which means that the reaction is basic. The temperature stayed the same but because the water was hot the reaction was more explosive and quicker. Before the phenolphthalein the solution was white, fig.3, and after dropping the phenolphthalein it turned pink, fig.4, which means that is a basic solution. Results Are your results in accordance with what you have learned about reactivity? Yes because calcium has more orbits the atom has the less energy it needs to give away electrons. In this case the atom that has more orbits is the calcium that is why it reacts more than the magnesium because calcium needs less energy to give electrons away. And the magnesium didnt react much because it needs more energy that the one that we gave it. Write the balanced equation for the reaction between Mg and H2O: Mg (s) + H2O (l) MgO (s) + H2 (g) Uncertainties Other element might have been present. The hot water might have been heated more. Conclusion We learned that both magnesium and calcium is basic solutions because of the pink tint to the color. We also learned that calcium reacted faster than magnesium.

COLLECTION OF BLOOD AND URINE SAMPLES The blood samples were collected from the retrorbital venous plexus of rats without any coagulant for the separation of serum, at the regular intervals of the treatment. After collecting the blood in effindraf tubes they were kept for 1 h at room temperature and serum was separated by centrifugation at 2000 rpm for 15 min and stored until analyzed for various biochemical parameters. Urine was collected over 24 hours on the 21st day by keeping the test animals in metabolic cages. The volume of collected urine samples was measured followed by estimation of biochemical parameters, namely urine Creatinine, urine uric acid and urine urea. 4.7. PARAMETERS MONITERED 4.7.1. BIOCHEMICAL ESTMATIONS i. Estimation of Urea (Berthelot Method) Principle: The reaction sequence employed in the assay is as follows: Urea + H2O Urease 2NH3 + CO2 NH3 + Salicylate +Hypochlorite Nitropruside 2-2-Dicarboxy Indophenol Urease catalyses the conversion of Urea to Ammonia and Carbondioxide. The ammonia released reacts with a mixture of Slicylate. Hypochlorite and Nitropruside to yield a blue-green colored compound (Indophenol). The intensity of color produced is proportional to the concentration of urea in the sample and is measured photometrically at 578 nm or with yellow filter. Reagent preparation: Transfer the entire Enzyme Concentrate (1A) into Urease Reagent (1) with the dropper (or) microtip provided. Assay Procedure: Pipette into test tubes labeled Blank (B), Standard(S), Test(T) as follows.

Bushs War On Terror and the Erosion of Civil Liberties Essay -- Polit

Bush's War On Terror and the Erosion of Civil Liberties Nearly all the amendments in the Bill of Rights have been reduced since the beginning of the war. The fourth through eighth amendments have been especially hit hard by this â€Å"war.† Search & seizure, due process, a speedy and public trial with a jury, and cruel & unusual punishment have all been disregarded as part of the current administration’s policy. The â€Å"War On Terror† has effectively eroded the civil liberties that Americans fought centuries for. Through the passing of the USA PATRIOT Act, the government can now search a â€Å"suspected† terrorist’s property without their knowledge and even without a warrant. Although this could be a well-needed exception to warrants, as it is the same way drug dealers and organized crime offenders have been investigated, identifying a â€Å"suspected† terrorist is not nearly as easy as an active criminal. As shown by the events of September 11, the terrorists that hijacked the planes were part of a â€Å"sleeper cell† which stays dormant until tipped off by somebody above them in the organization....

Community Essay examples -- Teaching Education

Community This article asks the question; why must schools invite the public to join the dialogue on public education? New structures and committees are being erected in communities across the nation to build stronger connections between schools, school boards, and communities. One such structure is a district advisory committee composed of community leaders. Its purpose is to improve the quality of communication between the school district and the community. It looked for ways to increase community ties to the schools, to make residents more aware of what was going on, and to gain community feedback. Though this committee in New Jersey has functioned well and is very supportive, an increasing concern is that divisions within the community might contaminate both the committee and school board. Schools and school boards need better communication from the community to better the efficiency of the schools. Community input plays a vital role in developing school goals. Students and parents have the most immediate stake in school quality, but the community also has significant interests in the schools. The public, or community, has an important role in public education. Three reasons arise as to why community involvement is essential for a stronger school system. First, only the community can create â€Å"public interest.† Without good communication on public interest, elected officials cannot properly determine what is best for both the schools and community.

The Use of Religion in Paintings during the Counter-Reformation :: Religious Art Artwork Catholic

Symbolism: The Way to Get Your Point Across â€Å"Baroque: Dominant style in western European art and architecture from late 16thC [entury] to mid- 18thC [entury]. Started in Rome, with the reassertion of Roman Catholicism in the Counter-Reformation. and then spread to northern Italy and other parts of Europe† as defined by a website containing nothing but art terms, is the time period that I chose to analyze how religion was used through paintings as ammunition for the Counter-Reformation. The Counter Reformation was a movement within the Catholic Church to reform itself in the midst of the Protestant Reformation. I am in awe at how we can look at something for just a short period of time and, in most cases, we can understand what is going on, or something hits us telling us what is meant to be seen or interpreted in a certain scenario. This process is called â€Å"thin-slicing†, as Malcolm Gladwell coined a phrase in his book Blink. In a very dark and some-what eerie painting—with the only form of light in the middle—that depicts a battle that has just been fought, the first thing that comes to mind is the thought of war and death. This painting can be found in the Lowe Art Museum at the University of Miami in the Renaissance and Baroque section. It is un-named and was painted by Giovanni Andrea Donducci, who was commonly known as Mastelleta, somewhere between 1611 and 1612. The historical time periods that do incorporate these two concepts prior to 1611 are endless. The fact that there is, what seems to be, a knight in the middle of the painting pointing to a city that is illuminated wearing plate and armor, it is deduced that this could be the Crusades. Upon further research, I have come to the conclusion that this image is most likely depicting the Crusades; due to the illuminated city, and the red flags, uniforms, and ornate pole arms, since the main colors were red and white. The Crusades were a series of wars in the name of God and Christendom, fought between Christians and Muslims, to claim the Kingdom of Heaven, also known as Jerusalem. The main symbol that is drawn out of these wars is God and Christ. The city that is illuminated in this painting could be Jerusalem and the people on mountain pointing towards the city could be the Christians fighting to reach the city and try to conquer it.

Newell Convers Wyeth Essay

Newell Convers Wyeth was one of the famous men in America during his time. This is because he was considered as one of the greatest American illustrators. He was the first to set the pace amongst the three generations of Wyeth artists. However, he was not only an illustrator but a painter as well. The work he did has become historical and is celebrated in many galleries, museums and publications as well as in other artist venues across the globe (Howell, par 1). Throughout his life, he was doing very well as an illustrator thus becoming very famous. N. C died in Chadds Ford in 1945 through an accident (Brandy Wine Conservancy 3). Wyeth gained national recognition as a result of his Scribner’s Classic Children’s Books like The Yearling, Robinson Crusoe, The Last of the Mohicans, Kidnapped, and Treasure Island among others. Wyeth believed that the deepest happiness a person can experience comes from living a simple life, and also treasuring the beauty and bounty of land and sea. Quite a number of Wyeth’s paintings were based on his feelings and own experiences. This was usually as a result of the memories of his parent’s farm where he grew up (Highlights for Children, par 1-8). N. C Wyeth started drawing when he was a child. He was being encouraged by the mother who helped him nature his gift. He began working for a magazine called the Saturday Evening Post when he was only 20years. Soon after this, his fame began to spread and his work published in other leading magazines like Harper’s weekly, Century, and Scribner’s among others (Nila McCann Spring). Despite the fact that Wyeth was an illustrator, he yearned to be known as a painter as well. The difference between the two was that illustration carried a pejorative connotation that Wyeth felt keenly all his life. In addition, regardless of the fact that commissioned work earned him income to support his family, he tried to run away from the confines of textual limitations, taking up personal paintings like landscapes, still lives and portraits. He moved from lyrical landscapes, which had an impressive style, to powerful portraits of fishermen that evoke the work of the American Regionalist artists. Nonetheless, he never attained personal satisfaction or the recognition that he wanted (Brandy Wine Conservancy 2). Wyeth was able to make three trips, between 1904 and 1906, to West America. This was after Wyeth recognized the value of Pyle’s instructions in his career. Pyle was one of the most renowned illustrators from Howard Pyle School of Art where Wyeth had joined then. During the period of the trip, he spent much of his time taking up the experience that enabled him to paint images. The painted images would allow him to come up very well and be among the top greatest illustrators during his error. Wyeth had managed to herald in Outing Magazines by 1907. He was one of the greatest painters of American outdoor life (Brandywines Conservancy 1). Early Life Nowell Convers was born on 22nd October, 1882 in a place called Needham, Massachusetts. His mother was the daughter of Swiss immigrants while his father was a descendant of the first Wyeth to arrive in the New World in the mid-17th century. His growing up in a farm made him develop a deep love for nature. He began his artistic inclinations at a very young age and the mother encouraged it. However, his father opposed this since he wanted him to use his talent more practically. He attended Mechanic Arts High School in Boston up to May 1899, where he concentrated on drafting. Through the support of his mother, he was able to transfer to Massachusetts Normal Art School and through the help and guidance of his instructor Richard Andrew; he took the line of illustration (Brandywine Conservancy 1). Wyeth married Carolyn Bockus in 1906. They met after he completed his learning under Pyle. They gave birth to five children whose names are Nat, Carolyn, Ann and Andrew. Some of these children resembled his father in his work of illustration and painting. They picked up talents for one art form or another, ranging from composing music to teaching art lessons and also to inventing (Howell, par. 3-4). N. C Wyeth trained his son Andrew through home schooling in 1932. This was after he realized that his health was failing. There were several challenges that came with school administration and also the expense of teaching his son from home. However, Wyeth managed to complete his son’s education as his teacher. After that, Andrew Wyeth continued to work under his father’s artistic guidance in their home in Maine which was named after the famous Winslow Home painting (Howell, par. 6). N. C Wyeth’s Work Wyeth is the perhaps the best and is remembered for his illustrations of other children classics done for Scribner’s. He gained national recognition with his illustrations for the book Treasured Island by Robert Louis Stevenson in 1911. He composed American stories and themes from carpetbaggers to Indians. He used color and romantic imagery brilliantly and this combined with his close attention to historical detail, enables his artwork gain a lasting place in the lexicon of American illustration. The love he had for America in-terms of its individuality and landscapes is evident in his works; that is, from the Old West to the Brandywine Hill. This was a country of Chadds Ford, Pennsylvania. It is said that his boldness and sometimes massive artwork expressed his ‘largeness of spirit’. He is also said to have painted murals on a heroic scale by one of the biographers (New World Encyclopedia, par 2-4). He managed to complete over three thousand works during his career. Being an illustrator, some of his famous works included publications like Kidnapped, Tom Sawyer, Treasure Island and Robin Hood. Between 1925 and 1935, he completed some of his most exhilarating pieces of work, among which were several experimental pieces that were seen as heroic compared to his commissioned work (Howell, par 2). The success of Treasured Island insured Wyeth along his career. Scribner’s illustrated many classic stories in his succeeding years. The most famous titles are; â€Å"kidnapped (1913), The Black Arrow (1916), The Boy’s King Arthur (1917), The Mysterious Island (1918), The Last of the Mohicans (1919), The Deer slayer (1925) and The Yearling (1939). † In addition, he created illustrations for other publishers. Examples of such books are Robin Hood by David McKay(1917), Robinson Crusoe by Cosmopolitan (1920), Rip VanWinkle by David McKay (1921), Men of Concord by Houghton-Mifflin (1936) and Trending Into Maine by Little Brown (1938) (Howell, par. 2). Books like Treasured Island and Robinson Crusoe by N. C Wyeth are the most historical and famous. They also have a maritime adventure and an Island as a center element of their schemes. In addition, the historical language used in every one of them is similar as well as one of the same nautical terminology like stern, bow and aft among others. This is utilized because of the aforementioned similarities (Enotes, par1-3). Checking closely, the characters in these two books are alike only in the most basic ways. In Robinson Crusoe, for example, Crusoe is a male just as are Long John Silver and Hawkins. In addition, both central character are seamen and in the case of Hawkins, they were trying to become such. On the desolate island, young Jim Hawkins is trying to survive as a lone boy in the world of men just as Crusoe tries. On the other hand, both books are written by male authors and that the masculinity tone is seen in both books. In this case, as one reads these books, each story helps them to gain a perspective into the oceangoing world of the past. May be a better comparison could be drawn between Stevenson’s in Kidnapped and Defoe’s in Robinson Crusoe because there are better similarities existing in these books (Enotes, par. 2-3). His work also contains religious paintings. For example in 1923, he is said to have been commissioned by the Unitarian Layman’s League to do a series of paintings which included ‘The Parables of Jesus’. His most superb religious work that consisted of three hinged panels painted for the Chapel of the Holy Spirit at the Nations Cathedral in Washington D. C seems to be welcoming believers. It consisted of Jesus surrounded by a host of heavenly angels. The wordings are, â€Å"Come unto Me, All Ye that Labor and Are Heavy Laden, and I Will Give You Rest† (New World Encyclopedia, par. 13). His other works included; Mowing (1907), Long John Silver and Hawkins (1911), The Fence Builders (1915), September Afternoon (1918), Dying Winter (1934), The Alchemist (1938), Deep Cover Lobsterman (1939), The war Letter (1944) and the Nightfall (1945) (New World Encyclopedia, par. 23). Assessment of N. C Wyeth’s Work It was appropriate for Wyeth to start his work at his young age. One of the reasons is because he was able to leave an impact after he died in that his work is still remembered to date. He also was able to raise his son Andrew as his successor and the son become famous too because he was doing very well. It was also of importance to begin his work at an early age since he was able to publish so many books like Treasured Island and Robinson Crusoe (Amazon Par. 1-3). In addition, this golden age work of Wyeth played an important role in uplifting and pursuing work in illustration. The period of golden age work was also recognized for unparalleled brilliance in publication of journal art which had not been seen before. Also N. C Wyeth plus other students were able to carry on Howard Pyle’s work and this also brings out the importance of his beginning work at a young age (Jo Ang, par 4-5). N. C Wyeth was also able to perfect his work over time by starting his career at a young age and this enabled him to gain fame in America and other nations too. The fame is evident in his created images for magazine advertisements and calendars, painting for big companies like Wheat Company, Coca-Cola, Blue Buckle Overalls, Steinway &Sons, New York Life Insurance among other (Brandy wine Conservancy 3). Conclusion Wyeth is remembered since he was one of the greatest illustrators in America and who created nearly 4,000 works during his golden age from 1903 to 1945 when he died. However he never achieved the personal satisfaction or public recognition that he wanted. N. C Wyeth gained national recognition as a result of his Scribner’s Classic Children’s Books like The Yearling, Robinson Crusoe, The Last of the Mohicans, Kidnapped, and Treasure Island among others. All these books are read even to date. Work cited Amazon. com. 1996-2010. The Amazon. com Review, 2010. Web. 15 May 2010 . Brandy wine Conservancy. N. C. Wyeth Biography.

Coffee in World History

Coffee in World History Coffee in world history has changed many things from its first appearance in 1635 up until today. Its effects were seen in the people, on the economy, and on the social aspect of life. These effects were mainly beneficial with some exceptions. Documents 1,3,5,7,8, and 10 show positive social effects on the people. While documents 1,3,4, and 9 show how the effects of coffee were seen positively on a worldwide scale.Whether looking close up in social communities, or looking at it as a global impact, coffee proved to have a very large and beneficial influence on how people lived their lives throughout history. Socially, coffee has changed history in very positive ways. In the Ottoman dynasty, people flock to these coffee shops and basically live on coffee as it has become a new daily routine for them as it has appeared in towns (Document 3). People gather at these shops, talk, conduct business, and to be social, thus spreading new ideas and news faster through th e city.Coffee has also brought many jobs to the people (Documents 5, 7, and 8). Document 5 shows all the people that coffee must go to, to get to their drinkers and shops, all the people who are involved in this process were given jobs because of coffee. The details of the jobs were shown through how the people were effected by them (Documents 7 and 8). The did effect the people in positive ways because the workers were able to all get fair and equal pay for the job without any social discrimination.Finally, the social bonuses of coffee are shown, while being biast, stating that coffee is a ready and east source of money, showing that you could benefit from it because of the high value of coffee (Document 10). A document that would help better prove the point to show that coffee changed the society in a positive way would be a document by a ruler stating all the positive effects and all the accomplishments the dynasty has made because of coffee. Coffee proved to be a very beneficial factor in society through popularity, jobs, and money made from it and would help you if you were involved with it.Coffee also showed up in worldly affairs, positively changing things such as relationships and trading between countries. Document 1 can not only be used as a social plus, but can also be seen as a worldly plus. This Document shows us the world’s views and first reactions to coffee, which turned out to be very good. Everyone loved it and it’s popularity exploded worldwide. Document 3 can also be used in both situations because it shows how people still reacted to coffee 145 years after it first appeared and people still seemed to be addicted.This Document could be seen as biast in one way such as it says that without contradiction, the drink has formed the workers’ breakfast, some workers still may not be able to reach shops that sell coffee or may not be able to afford it. Different country’s views on the actual total consumption and export s were also shown in Document 4 and Document 9. Annual consumption (Document 4), was shown in 50 different countries ranging from 0. 1 kilograms per person in Kenya, to 9. 2 kilograms per person in the Netherlands. The countries total exports (Document 9), had 19 countries included, ranging from Brazil with 7. % coffee exports to Uganda with 94. 5% coffee exports. Another Document that could be added to help support the positive effect that coffee had on the world would be a document written by different Kings scattered across the world about how much their kingdom has improved by the invention of coffee and how economy, and jobs, and the social aspect of life has gone up. These documents were important to the world’s benefit from coffee because it showed that since the trade of coffee went up, economy went up, helping money fluxgate throughout the world.Although document 1 could be seen as a positive for both social and worldly benefits, it has yet another side, a negative f or the communities. As more and more people began to become attracted to these coffee shops, they began to attend work and the temples less and less, creating the beginning of a problem for some people. Other than the problem of some people avoiding jobs in exchange for time spent drinking coffee, its impact was mainly positive.This document could also be biast because of if the people in that particular place actually have time and money for coffee, or if they enjoy their jobs, they wouldn’t be flocking to this tiny shop to socialize and to drink. If another document were to be added to this picket, it would need to be a document written by people in different jobs such as a priest, a coffee shop owner, a merchant, or a trader of coffee. The point of this document would be to better understand coffee’s effect on different jobs and really determine if the effect on the job changed the job holder’s take on coffee.This document would help really tell if the effect s on the social aspect were beneficial according to the people, not just the overseers. From the beginning of when coffee first appeared, until now, there has been many coffee influences on history. Through society, coffee has changed the way we live, and how coffee has changed our jobs. In worldlier views, coffee has changed our economy, trade, and relationships with other countries. Coffee proved to have a very large and beneficial influence on how people lived their lives throughout history.
