Synthesis of Aspirin (Acetylsalicylic Acid) Abstract: This experiment is about the synthesis of aspirin under laboratory conditions. Aspirin is prepared by reacting salicylic acid and acetic anhydride; in the presence of sulfuric acid. After fully dissolving the salicylic acid with acetic anhydride‚ the solution is cooled and cold water is then added. Once the crystals form they are then filtered and left to dry out. There mass is measured and recorded then the yield is calculated. Introduction:

The Awakening Synthesis Essay When a woman decides to abstain from having children‚ her choice is not taken lightly by peers around her. A woman is expected to find a partner‚ get married‚ have children‚ and be their primary caregiver. Psychologically‚ a woman’s social clock‚ also known as a cultural timetable for certain events to occur‚ is ticking as she feels the need and urge to accomplish each task that is expected of her. A significant author‚ Kate Chopin‚ considers the social clock insignificant

Research Synthesis On Friday‚ January 11th‚ students from the Waukee metro mourned the loss of their fellow classmate Drew Lieneman‚ 18‚ after he took his own life. Although Drew was the captain of the football team‚ a respected leader at Waukee high school‚ and a friend to many‚ he suffered from a burden of “loneliness” and “isolation” according to an interview with his parents on the Channel 13 News. Drew was not the only teen to take his own life during this 2015-2016 school year. Luke Anderson

there are two esters that are very close in molar mass‚ methyl acetate and ethyl formate. The methyl acetate and the ethyl formate both have a molar mass of 74.08 g/mol [5][6]. The last step is to distinguish between the two. Both methyl acetate and ethyl formate are described as having a “fruity odour”‚ relatively close boiling points and the same colourless appearance [5][6]. However‚ there is one source that says that methyl acetate has a “characteristically pleasant smell reminiscent of some glues

November 15‚ 2007 Synthesis of 1-Bromobutane Introduction: The purpose of this experiment is to synthesize 1-bromobutane from 1-butanol and sodium bromide. In order for this reaction to reach completion there are four major operations that need to be performed. The four major operations include refluxing‚ simple distillation‚ separation‚ and drying. To begin‚ in order for the compounds to react they will be dissolved in water and sulfuric acid will be added. The addition of sulfuric acid will

THE SYNTHESIS OF MONSTER INC. In Monsters Inc. At the beginning of the story‚ depicted a company belonging to the monsters that find and produce energy from the screams of children being made afraid by them. They’re harvesting energy to keep from becoming extinct by going back to when humans were most prominent. Monsters must have relied on anti-human instincts to believe that just touching a human would corrupt their world like it did in the past. So they scare humans to gather their energy until

However‚ backstreet abortions were done‚ often ending in permanent injury or death. The 1967 Abortion Act was introduced to provide a safe alternative to backstreet abortions (Abortion). In 1973‚ the Supreme Court handed down its Roe v. Wade and Doe v. Bolton decisions legalizing abortion in all 50 states during all nine months of pregnancy‚ for

Our data displayed supports the notion that by increasing the acidity of the catalyst‚ the production of aspirin will increase. Our hypothesis was proven correct. In our data‚ we calculated the percent yield and percent error of each trial. We also calculated the average of the percent yields and the percent errors of each catalyst. In the end‚ we saw that for the sulphuric acid catalyzed aspirin‚ we saw an average of 69.7% percent yield and an average 30.3% percent error. As for the phosphoric acid
