At the beginning of the lab‚ a micro test tube with and without glass wool was weighed on an analytical balance. A watch glass‚ crucible‚ and lid were also weighed. The masses of all the materials needed for the lab were recorded in the data tables of the laboratory notebook. An unknown vial was obtained from the teacher and set to zero on the balance. About 0.6 grams of the unknown was measured into the micro test tube. The analytical balance was set to zero again and then the test tube with the

Obama Administration to propose the reduction of ethanol usage. This proposal has caused a sudden outrage by farmers who make a living off of corn-based ethanol (Brush‚ 2014). Many are concerned that this sudden proposition could be a tremendous drawback in the alternative energy industry. However‚ with current technological advances the world of ethanol could significantly change and impact in the near future.

Abstract Vitamin C‚ also known as ascorbic acid‚ is a water soluble vitamin that is regarded as one of the safest and most effective nutrients. Vitamin C can be found in most fruits and vegetables. The goal of the experiment is to find out the concentration of vitamin C in three citrus fruits‚ orange‚ lemon and lime‚ and to compare them and find out which fruit contains the highest concentration of Vitamin C. By using the juice from each fruit to make a solution to combine with 10cm³ of DCPIP until

Ethanol sensitivity in Drosophila melanogaster based on genotype Alexa Shumate Department of Biology Randolph-Macon College Ashland‚ Virginia Introduction With a better understanding of the genes and behaviors associated with ethanol sensitivity‚ there will be new treatments available for alcohol dependence. The main problem in determining what causes dependence to alcohol is whether it is an environmental factor or if it is the genes associated with ethanol

Abstract: The purpose of this lab is to prepare phenylmagnesium bromide‚ a Grignard reagent‚ and react it with benzophenone to give triphenylmethanol. Once made‚ the Grignard reagent will do a nucleophilic attack on the carbonyl carbon of the ketone‚ benzophenone. The result is an alkoxide that is then protonated to give the alcohol‚ triphenylmethanol. The purity of the final product will then be considered by melting point and IR spectroscopy. Final purified triphenylmethanol weighed 8.02 grams

Abstract Abortion is a very conversational topic‚ but abortion is something that should an option for all women. If you’re pregnant‚ you have the right to decide if abortion is right for you or not; not everyone is ready to have a child. Abortion has been made legal in 1973 by the U.S superman court‚ but it is still an open and widely discussed topic. There have been new laws that prevent abortion‚ making it harder for an abortion to take place. It is unfair for government to changes the rules as

Objective: The benefit of this lab was to acquaint oneself with the fundamentals of the Aldol Condensation reaction by demonstrating the synthesis of dibenzalacetone (trans‚ trans-1‚5-Diphenyl-1‚4-pentadien-3-one) through the aldol condensation of acetone with benzaldehyde. The synthesis began by using a strong base to generate the acetone enolate ion. The ketone/enol tautomerization is an equilibrium process that produces little of the enol (ppm or less). However‚ any enol that formed quickly reacted
