My Personal College Essay By Dina Elyamany My heart froze and my stomach churned as I imagined the red-colored blood gushing out of him like a waterfall. I grabbed my doctor equipment and‚ with shaking hands‚ started stitching the wound in his chest with fear that something might go wrong. After sealing the cut‚ I checked the heart monitor‚ and a big smile appeared on my face. My teddy bear was safe and alive‚ and I was an outstanding six-year-old doctor. After finishing surgery‚ I skipped into

Experiment 2 and 3: Synthesis of Aspirin and Determination of Melting Point A. Abstract Aspirin is the common name for the compound acetylsalicylic acid‚ widely used as a fever reducer and as a pain killer. The first part of the experiment aims to synthesize aspirin from the reaction of salicylic acid with acetic anhydride with the aid of phosphoric acid as a catalyst. The second part of the experiment aims to assess the purity of aspirin through the determination of its melting point and

Colleges should reduce tuition because middle to poor class citizens that want to higher their education cannot go because it’s too expensive. The aides of lowering college tuition fees include the statistic that higher education is often a standard job requirement in many fields‚ but also that lower tuition costs increase the accessibility of education‚ which in turn creates social freedom of movement that is often helpful to the economy. Regardless of the advantages of low-cost or free higher education

Sucrose Synthesis by D. DeWitt‚ PhD v1.5 11/10/12 Introduction | Condensation Reaction | Plant Synthesis | A. Introduction Although it might seem straight forward‚ the synthesis of sucrose‚ either as a simple condensation reaction (a.k.a. dehydration synthesis)‚ or what actually happens in plants is complicated. Before we explore sucrose’s creation‚ let’s take a look at its structure. In Figure 1‚ the space-filling model is pretty but rather useless at this point in our journey. We

Synthesis of Aspirin Learning Goals 1. To synthesize aspirin from salicylic acid and acetic anhydride. 2. To purify the crude product by Recrystallization. Introduction Most drugs are chemical compounds which are described as "organic compounds" because they are comprised primarily of the elements carbon‚ hydrogen and oxygen. The present experiment will be the synthesis of a familiar organic compound called aspirin. The common chemical name is acetylsalicylic acid. Aspirin‚ the

Jeana Greaves Chem3301-112 June 19‚ 2013 Synthesis of Aspirin from Methyl Salicylate Introduction The synthesis of Aspirin (Acetyl Salicyclic Acid) began with methyl salicylate and sodium hydroxide as the reagent. The polar oxygen accepts the electrons from now positively charged hydrogen. The positively charged sodium disassociates leaving the hydroxide ion with a negative Scheme 1 shows the mechanisms that were demonstrated during the synthesis of Aspirin. charge that attracts to the positively

training sessions are costly the return a company gets from it is worth the investment. A company that constantly sends its employees to school to acquire a fresh and new ideas has a greater advantage than a company that do not offer such benefit. Tuition reimbursement is one of the many benefits an employer offers to attract a potential employee or keep a good employee in their company‘s work force. It is important for companies to send their employees to trainings or schoolings because the data used

U‚ and C for the nucleotides guanine‚ adenine‚ uracil and cytosine) that directs synthesis of specific proteins‚ while many viruses encode their genetic information using an RNA genome. Some RNA molecules play an active role within cells by catalyzing biological reactions‚ controlling gene expression‚ or sensing and communicating responses to cellular signals. One of these active processes is protein synthesis‚ a universal function whereby mRNA molecules direct the assembly of proteins on ribosomes

The first synthetic sweetener‚ saccharin‚ was discovered five years prior to Dulcin. The discovery of Dulcin occurred in 1883. Approximately seven years after it’s discovery‚ J.D. Reidel‚ of Berlin‚ was able to synthesis Dulcin at a reasonable cost. Once it became possible to synthesis at a reasonable cost‚ mass production of the sweetener began. Dulcin was favored over its competitor‚ Saccharin‚ because it did not possess a bitter aftertaste. For a very brief period of time Dulcin was marketed
