Organic compound Essays

On the date of April 11th, 1899, Elizabeth Lena Adams, and James Sumner Julian, brought little Percy Julian into the world. Little did they know, that their African American son, born and raised in Montgomery, Alabama; would become one of the best chemists America has ever come to name. And it all started with this boy’s love for plants, his father’s adoration for plants and the magic behind their stems. ◊ Amidst his youthful times, Percy was an astute and devoted student, who sought to ascertain

Introduction The organic compound catecholase is commonly found in plants and consists of two substrates called catechol and oxygen. When these substrates react with each other they form a brown color, often seen in vegetables and fruits left out after being cut open. (Wahlert and Holland, 1999) This reaction is why when a potato is cut open and left to sit, it will begin to brown. During the genetic mutation of potatoes, scientists can limit the amount of the substrate which causes less severe browning

Plants function through photosynthesis and because of proteins. These proteins are created by amino acids. Since I find nature so interesting, finding the different amino acids in various types of

activities. Deforestation appears to be the major concern as once the land is converted into dry lands, it can hardly be made fertile again. Those areas inevitably end up as waste lands. Mining requires the removal of topsoil containing valuable organic matters. The removal of topsoil causes the land to be barren which are unsuitable for cultivation and unproductive, which is a kind of land pollution. Due to urbanization, many construction activities are taking place. Waste materials such as wood

In the talk, “Adventures in Organic Chemistry – Over Three Decades of Synthetic Organic Chemistry” presented by Dr. Chris Condeiu, he tried to relate the industry of organic chemistry to a students’ perspective. Three major points were drawn out through the talk. The first was the perspective of how capitalism drives the industry and the mechanism of doxycycline was formed. With an overview of his talk, the expectation was that a deeper understanding of how pharmaceutical drugs’ mechanisms are formed;

During the circle time, Caydence sing a song along with her peers, ABC Song, “A,B, C, D, E, F G, H, I, J, K,….O,P, Q, …., my A, B, C, ne…..sing wit.. me.” Next, the teacher uses the cards of shapes. When the teacher shows cards of shapes and everyone says the names of shapes, Caydence says, “Circle, star, square....”: she does not say all names of shapes. Then the teacher shows the cards of colors, Caydence says, “Red, blue, yellow, green, orange, pink, purple…” as the teacher shows the cards:

Analyses - Let America Be America Again Langston Hughes uses a varied meter in “Let America Be America Again”. In the first line and title of his poem he starts with the first syllable [let] stressed, followed by a unstressed syllable [a]. This trochaic dimeter is used just for the first four syllables, following a iambic tetrameter starting with [ca] unstressed and [be] stressed. The second line starts with a trochee, but this time with eight syllables, therefore a tetrameter. The last syllable

It is “foolish men” who fail to see that acute insightfulness is a vehicle for precise thinking. Nevertheless, the speaker shuns drawing conclusions about whether the creation of art contributes to, or ease madness, by attributing her speculations to theories others have proposed. In the final lines of the poem, however, she endorses the decision to explore dark corners of the mind and expand the limitations of the self by drawing attention to the affective dimension of the work, the beneficent effect

The Red Wheelbarrow The Red Wheelbarrow is a poem written by an American poet called William Carlos Williams. Initially, the poem was published without a title, and the poem is in form of verse form. Williams in his writing constructs an image within the readers mind. The author uses simple words to construct a poem that is basically based on imagery philosophy. Williams’s poem is all about a red wheelbarrow that is painted in the readers mind in order to create a flamboyant picture. The Red Wheelbarrow

The poem “A Fit of Rhyme against Rhyme” is a response to Samuel Daniel’s prose essay A Defence of Rhyme, in which Daniel describes rhyme as an “antidote to endless motion, to confusion, to mere sensation, to the sway of the passions” (Reading the Early Modern Passions: Essays in the Cultural History of Emotion, 146); while Jonson’s response describes rhyme as a “rack of finest wits, that expresseth but by fits true conceit” (1072, 1-3). Jonson’s poem ironically uses rhyme to ridicule rhyme in a

techniques such as recrystallization, extraction, melting point, and acid-base reactions. From this, the group to which these two compounds belong to had to be determined. These groups are: Carboxylic Acids, phenols, and neutrals. By determining the melting points of the two unknown compounds, these values were compared to the values of melting points in the chart and the proper compound was selected. For the case of this experiment, the unknown mixture contained, 4-methylbenzoic acid. The neutral was not

difference in the solubility of a compound between two immiscible liquids1. After the unknown compounds were extracted, isolated, and recrystallized they were identified by their melting point. These were then matched with a list of compounds given; with their solubilities and melting point

presented in a qualitative table and further discussed. There are 6 possible substances that the 2 unknowns could be. If the substance is benzoic acid then it would have to pass the organic solvent test because it dissolves in only organic solvents, while if it were silicon dioxide it would fail both solubility tests for organic and aqueous solvents. When doing the flame test, if the flame colour of the substance is yellow then it is either sodium chloride or sodium carbonate. The difference between sodium

determine the chemical formula for a hydrated compound called a copper chloride hydrate. A chemical formula is made up of letters and subscripts that give the amounts of the elements in a substance. This compound contains the elements chlorine, copper, and water molecules that are locked in the solid compounds crystal structure. The chemical formula will be found using John Dalton’s law of definite proportions, which is when “every chemical compound contains fixed and constant proportions (by weight)

structure of the unknown compound. By observing whether the compound is soluble in water, it is possible to determine whether the substance is a polar covalent molecule or an ionic compound. If the compound doesn’t have the ability to be soluble in water, it can be identified as a covalent network lattice, covalent layer lattice, a non-polar covalent molecule or a metallic compound. When the substance is soluble in water (for example an ionic compound), it generalizes that the compound usually has a weak

predominant molecules found in living organisms. In analytical chemistry, indicators are chemicals (reagents) that help identify the composition of an unknown material. In solution analysis, indicators are used to predict the presence of certain organic or inorganic compounds such as sugars, proteins, starches, lipids, or vitamins. There are two types of testing, qualitative

Healthcare employee safety is very important and should be a high priority. In the healthcare setting the employees must pay attention to his or her surroundings. This essay will include several objectives such as injury prevention, emergency readiness, and training. Keeping the employees safe is not easy while working in the environment full of dangers. I will discuss the importance of employee training, personal safety, safety slogans, environmental safety and informational posters. INJURY PREVENTION:

French fries shouldn't be served in school cafeteria Without a doubt, French fries are one of America's favorite food and a huge part of the fast-food chain. French fries may seem the least of all evils when perusing a restaurant menu but what people may or may not know is that a medium order of fries has 365 calories along with 17 grams of fat which equals 26% of your daily value and 10% of the upper limit you should eat in a day. Haven't you ever asked yourself where do French fries come from?

Chemistry, compounds are defined as any substance that is composed of atoms of two or more elements that are combined in fixed ratios. Compounds can often be reduced in order to separate their elements and study their properties. Compounds such as water (H2O) and Carbon Dioxide (CO2) for example, both contain oxygen and can therefore undergo a process of decomposition that will isolate the elements in order to calculate the quantity of each element and molecule present in the compound. Any compound with
