Synopsis The purpose of this experiment was for students to prepare some simple organic compound and to purify the compound by recrystallisation. This experiment allowed the students to conduct the synthesis of aspirin‚ acquire the skills of recrystallisation using normal filtration and reinforce the technique of the melting point determination. The method used to synthesize aspirin was esterification by reacting salicylic acid with acetic anhydride with the presence of dehydrating agent‚ conc

Colton Kuhlers Chemistry Paper Organic vs. Non-Organic What should I eat‚ organic or non-organic? This has been is hot topic a lot now that the United States is trying to go healthy. For years people have been researching which is healthier‚ more economical‚ and the most available than the other. It is hard to know what to buy when one researcher says organics better and another researcher says non-organics better. Let me take this topic into more depth to explain myself. First‚ let’s me describe

Title: to get organic food Specific purpose: Organic food advocates claim that organically grown foods are safer and more nutritious than foods raised with non-organic methods such as pesticide and non-organic fertilizer use‚ or antibiotic and hormone use. Thesis statement: Many people just don’t trust these chemicals and don’t want to put them into their bodies. Since virtually all non-organically produced foods contain residues of pesticides‚ fertilizers and other chemicals‚ the only way to

Chapter 3 1. 1 atom of X = atomic mass (amu) 1 mole f X=atomic mass in grams 1 mole of something = 6.022 x 1023 units of that substance 1 mole of a compound =66.022 x 1023 atoms 6.022 x 1023 amu =1 g 2. What is the mass of 6 atoms of Fe? Answer: 6 atoms of Fe x 55.85 amu÷atom of Fe x 1 g of Fe÷6.022 x 1023 amu = 3. How many atoms does it take to make 1 g of Gold (Au)? Answer: 197.0 g Au =1 mole of Au

Use this packet and your book to answer the questions throughout this packet. Organic Nomenclature - Alkanes‚ Alkenes‚ Alkynes Naming organic compounds can be a challenge to any chemist at any level. Historically‚ chemists developed names for new compounds without any systematic guidelines. In this century‚ the need for standardization was recognized. For simple molecules‚ the nomenclature system worked out by the International Union of Pure and Applied Chemists (IUPAC) works well. For complex

Megan Wierzbowski Organic II Laboratory Wed. 11-1:50 Title: Grignard Reaction with a Ketone: Triphenylmethanol Part 1 Objective: The goal of this experiment is to learn to make Grignard reagents. The reactions of the Grignard reagents with ketones form tertiary alcohols. These reagents are highly air- and moisture-sensitive materials. We will observe the formation of the Grignard reagents‚ which magnesium metal is transformed into organometallic salts. Experimental Procedure:

Acid Reflux or Gastroesophageal Reflux Disease (GERD) is caused by stomach acid rise towards the esophagus and cause pain in the solar plexus or a burning sensation in the chest. The cause of acid reflux (GERD) is the proper functioning of the lower esophageal sphincter (LES). LES is a circle of muscle at the bottom of the esophagus. LES serves as the automatic door opens when food or drink down to the stomach. After the food came in‚ the LES will be shut down to prevent the existing food and acid
