Lab Report Synthesis and Characterization of Aspirin (Acetylsalicylic Acid) The Synthesis and Characterization of Aspirin (Acetylsalicylic Acid). Summary: In this experiment‚ we produced 4.21 g of acetylsalicylic acid. Our theoretical yield was calculated to be 5.22 g. Therefore our % yield was determined to be 80.6%. The experimental boiling point range of acetylsalicylic acid was found to be 130-132° C. The true melting point of acetylsalicylic acid is 135° C‚ therefore our percent

Why Beloved Should Still be Taught in School The concept of having Beloved banned in public schools is just a ludicrous idea and should be removed by the schools that currently enforce it. Although many students may not like reading‚ the book helped me realize the importance of the things I take for granted after reading the book. Beloved should still be taught in schools because of the major values it teaches including racism‚ family‚ and the true meaning of freedom. Beloved helps recognize

book you want to read‚ but it hasn’t been written yet‚ then you must write it.” (Morrison). In reading Toni Morrison’s short story “Recitatif‚” there are several things that Morrison does for her readers that allow us to relate and make the story our own. Morrison is a prime example of how language and translation play a role in the reader’s experience and what the reader takes away from the story. In “Recitatif” Morrison also helps the reader understand how much the past affects one’s future. “The

Protein synthesis is the process whereby proteins are produced‚ or synthesized‚ in living things according to "directions" given by DNA (deoxyribonucleic acid) and carried out by RNA (ribonucleic acid) and other proteins. As suggested earlier‚ this is an extraordinarily complex process that we do not attempt to discuss here. Following synthesis‚ proteins fold up into an essentially compact three-dimensional shape‚ which is their tertiary structure. DNA contains the instructions for a cell’s structure

Cry‚ the Beloved Country is a social protest against the structures of the society that would later give rise to apartheid. Paton attempts to create an unbiased and objective view of the oppositions. This requires that he depicts the Whites as affected by ’native crime’‚ while the Blacks suffer from social instability and moral issues due to the breakdown of the tribal system. It shows many of the problems with South Africa such as the degrading of the land reserved for the natives‚ which is sometimes

Formal Report no. 1 Synthesis of Aspirin Chemical Principles Aspirin is most widely sold over-the-counter drug. It has the ability to reduce fever (an antipyretic)‚ to reduce pain (an analgesic)‚ and to reduce swelling‚ soreness‚ and redness (an anti-inflammatory agent). Much of this is believed to be due to decreased production of prostaglandins and thromboxanes. Aspirin’s ability to suppress the production of prostaglandins and thromboxanes is due to its irreversible inactivation of the cyclooxygenase (COX)
