CH201L S.Y. 2014-2015 Analysis of Oxygen-Bearing Organic Compound 2 BS Chemistry‚ College of Science‚ University of Santo Tomas Espana‚ Manila Philippines 1015 Abstract An unknown sample was given along with five standards to test the presence of oxygen in the sample. The unknown sample underwent five different chemical analysis namely Dichromate test‚ Tollen’s test‚ Lucas test‚ DNPH test‚ and Iodoform test. Each test will determine if the unknown sample will have the same reaction as

Avoid contact with skin‚ eyes and clothing Hexane C6H14 -95°C 69°C 0.6548 g/ml Flammable Procedure: Refer to the microscale lab in pages 124-130 (15.1 and 15.2) in Modern Projects and Experiments in Organic Chemistry: Miniscale and William Microscale. Observations: Mixture of magnesium with bromobenzene turned into a yellow coloration after the bubbling. After much heating‚ the mixture turned into a brownish-mahogany color. The mixture did not recrystallize

Experiment In this experiment a high vacuum sublimation was performed to determine the vapor pressure and finally the enthalpy of sublimation of Vanillin and o-Vanillin. AKnudsen cell with sample was weighed 10 times maybe just say weighed by difference‚ they don’t usually like it when you spell out the steps like that no way it was like 0.5 grams‚ check the lab again and at least 0.5 g of Vanillin or o-Vanillin was added to the cell and it was reweighed 10 times. This experiment depended heavily

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
