Synthesis of Aspirin and Tylenol Kyla Wykoff Abstract Aspirin and Tylenol were synthesized by means of crystallization‚ recrystallization‚ and melting point determination. Synthesis produced significantly high percent yields for aspirin‚ however‚ produced extremely low and impure percent yields for Tylenol. A second group was also used to compare results and errors‚ in which they too were also producing extremely low percent yields of Tylenol. Therefore‚ error was based on the specific protocol

0.22g (percent yield of 86.9%). The percent yield after recrystallization‚ was 80.9%. INTRODUCTION The goal of this experiment was the synthesis of 3-nitrochalcone from 3-nitrobenzaldehyde and acetophenone as shown in Figure 1: Figure 1: Synthesis of 3-Nitrochalcone from 3-Nitrobenzaldehyde and Acetophenone Source: cnx.org The mechanism for the synthesis of 3-nitrochalcone is presented in Figure 2.

Synthesis Essay Gender Identity‚ Stereotypes‚ & Inequalities: Problems & Solutions Directions: The following prompt is based on the accompanying sources. This question requires you to synthesize a variety of sources into a coherent‚ wellwritten essay. When you synthesize sources‚ you refer to them to develop your position and cite them accurately (you should cite both direct and indirect references). Your argument should be central; the sources should support the argument. Avoid summarizing sources

In “Helping Students Use Textual Sources Persuasively‚” Margaret Kantz talks about how individuals should read texts to write a synthesis essay. To write a synthesis essay‚ one should be able to come up with an argument and find information from other sources‚ and use them as proofs to back up the argument. First‚ Kantz talks about the mistakes that students usually make when they write this essay. For instance‚ Shirley made a mistake by reading a repeating and telling the story instead of creating

Materials and Methods In the experiment‚ a frog was obtained and dissected in a way to expose its heart and then tested using Lab Tutor software‚ a force transducer‚ and the PowerLab hardware (ADInstruments 2014). Frog dissection: Frogs that had been killed by being double-pithed were dissected as described in Lab Tutor. The frog was pinned down with the ventral side up. A longitudinal and a lateral incision were made along the frog’s abdomen. The skin was peeled back and the tissue and sternum

MoxeyLab Partner: Lynden Cooper Synthesis of Aspirin (Acetylsalicylic Acid) Abstract:- Aspirin (acetylsalicylic acid) is produced experimentally in the lab. The resulting percentage yield is 65.5%. The purity of the obtained product is tested using the melting point and Ferric Chloride Test (FCT). The aspirin was massed‚ and the melting point was determined. Based on the data collected‚ there was a total
