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

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:

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

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

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

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

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

Physically, the unknown compound was composed of white, grainy, crystal-like structures. The unknown was also odorless. From these observations, various physical and chemical testing was performed to determine properties of the unidentified compound. A series of solubility tests were performed, as shown in Table 2, and revealed that the unknown compound was soluble in water, but not in Acetone or Toluene. Because the compound dissolved in water, it is known that the compound is either polar or ionic3

and mixtures. A pure substance is a substance with a fixed structure. We can classify a pure substance by its physical properties such as melting or boiling point. A pure substance is seen as an element or a compound. You can find the element information on the periodic table. And a compound is made up of multiple elements. A mixture does not have a uniform structure and has more than one substance in it. A substance can be classified as homogeneous or heterogeneous. A homogeneous mixture is described

Chanel N '5 is not only distinctive in its composition, besides it uses one of the first aroma compound fragrances of synthetic notes known as Aldehydes, scented like a florescent soap of citrus. (2) This doesn’t actually mean the chemical compound lowers the quality of the product but instead these synthetic notes results in unique expressions than using the actual notes from actual flowers and plants. (2) Besides, everlasting in its beauty, integrity, Parisian style, and rigid quality, none of

we found Sand and NaCl to be the majority of the mixture, however in reference to the Law of Conservation of Mass, we found a slight discrepancy in the final results. Introduction The purpose of this experiment was to determine the amount of each compound is found in the original mixture. Starting with a mixture of substances the components of the mixture should be able to separate. During this separation all of the components together should have the same mass as that of the starting mass of the

Experimental Procedure Identifying the Unknown We performed three tests on our compound to definitively identify it. First we combined 5 g of our unknown compound with 10 mL of distilled water and measured the pH change in the water to test its solubility. Then, to try to identify the cation present in our compound and narrow down the possibilities, we held a sample over a flame and watched for color change. We performed an acid test where we applied a few drops of HCl and watched for a bubbling
