I have very few memories of the day that I obtained my first concussion in the spring of my sophomore year at Tulane. I was feeling stressed that day‚ I had an Organic Chemistry quiz the next morning and was squeezing in study time between classes and diving practice. At practice‚ thoughts of Organic Chemistry were distracting me from my work out; I remember leaving the board‚ and then seeming to reappear on the pool deck with my coach barking at me in a language I did not understand. I just stared

disadvantages between the use of genetically modified foods and the use of organic foods. Do the benefits of organic foods overcome those of GM foods? Genetically modified food has many advantages‚ but with every advantage follows a disadvantage. GM foods grow at a much faster pace than organic foods‚ but they can be harmful to the environment. Inorganic foods are sold in large quantities for a low cost‚ while organic food for being sold in smaller quantities for a larger price. The price difference

were used to determine the melting point. 6. The bicarbonate extract was acidified with concentrated HCl. A piece of litmus paper showed that it was acidic. 7. The benzoic acid was extracted by shaking it with25ml portions of dichloromethane. The organic extracts were collected in a pre-weighed Erlenmeyer flask and evaporated on the steam bath. The mass of Benzoic acid produced was determined. RESULTS (i) Naphthalene: 0.85g; Benzoic acid: 0.71g (ii) The melting point of Naphthalene: 80-89º

project was conducted to test the effectivity of organic and synthetic fertilizers when apply on okra plant. It also aims to test whether‚ which is better to use between the two fertilizers. In order to conduct the study‚ we have used okra seeds‚ polyethylene bag‚ and dried leaves as organic fertilizer‚ synthetic fertilizer‚ synthetic fertilizer‚ and natural soil. We have planted each polyethylene bag with 3 seeds of okra‚ labeled it as Setup A (Organic fertilizer)‚ Setup B (Synthetic Fertilizer)‚ And

Structural Effects on Stability and Reactivity. Organic Chemstry Laboratory Structural Effects on Stability and Reactivity Introduction The concepts of stability and reactivity are fundamental to understanding chemistry. In this chapter we consider first the thermodynamic definition of chemical stability. We then consider chemical kinetics (Section 3.2) and how it can provide information about reactivity. We also explore how structure influences stability and reactivity. We want to learn how

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
