Benzene

The low yield for this lab was most likely due to the low generation of the Grignard intermediate due to exposure to atmospheric water. If the flask was left open for too long, water in the atmosphere would react and instead produce the by-product benzene instead of 1,1-diphenylethanol. Also some product was lost…

cells by the use of a specific primary antibody that binds to it. A staining reagent or chromagen is used to help detect certain proteins used in this experiment, called 3,3'-Diaminobenzidine (DAB). 3,3'-Diaminobenzidine (DAB) DAB, a derivative of benzene, is an organic compound, which is both chemically and thermodynamically stable, used in the staining of nucleic acids and proteins, most commonly for immunohistochemical procedures. Although it is water soluble in its unoxidized form, it…

Environmental pollution is a major concern in a number of countries world over. Human activities coupled with inadequate knowledge on the need for a clean and safe environment enhance the unending contamination of the environment. Ohio, just like other states, experiences environmental contamination. Drugs and drug metabolites including the industrial effluents are the major sources of contaminants in the local environment of Ohio. Combustion of the municipal and industrial compounds and…

at the Marine Corps Base in Lejeune, NC, it was discovered that two on-base water-supply systems were contaminated with the volatile organic compounds trichloroethylene (TCE), a metal degreaser, and perchloroethylene (PCE), a dry cleaning agent. Benzene, vinyl chloride, and other compounds were also found to be contaminating the water supply systems. The water systems were contaminated from August 1953 through December 1987". Unfortunately, there is a huge lag between the time it was discovered…

Morgellons disease has attracted attention since 2002 because there are many people complained of itching with no known definite causes. In 2002, a mother from Pittsburgh named Mary Leitao is launching a website that shows cuts in the skin and structures such as filaments or fibers in the skin of her son who was 2 years old. Since then nearly 14,000 families reported the same case, the condition is referred to as Morgellons disease. Morgellon's disease is a condition that is very controversial…

 The operating pressure is 0.3kg/cm2 and 4.3 kg/cm2 in the second column.  All isomers of xylene was recovered from the column and were collected. The results obtained were 97 mole% benzene, 96 mole% toluene and 98 mole% xylene. In this process separation of acetonitrile from waste solvent acetonitrile is carried out.  The impurity contains isopropyl acetate, hydrogen cyanide, acrolein, oxazole. The temperature of the process is between…

Lymphoma Ryan Jones Mr. Reeves Biology Honors April 24, 2018 Introduction Lymphoma is the name of a diverse group of cancers of the lymphatic system, a connecting network of glands, organs and vessels whose principle cell is the lymphocyte. Lymphoma originated from new Latin, dating back to 1870-75; lymph-,-oma. When lymphoma occurs, cells in the lymphatic system grow abnormally. They divide too rapidly and grow without any order or control. Too much tissue is formed and tumors…

DISCUSSION There are three chemical properties will be discussed which are combustion, reaction with bromine and reaction with potassium permanganate. Combustion was used to test the unsaturation of hydrocarbon. The degree of unsaturation refers to the number of the rings and / or multiple bonds present in the hydrocarbon molecule (McMurry, 2015). Hexane was a saturated hydrocarbon, it completely combusted and emitted carbon dioxide plus water. Cyclohexene was an unsaturated hydrocarbon, it…

Scientists make important contributions to technology and medicine through their discoveries. Nikola Tesla is distinguished for his futuristic inventions which serve as components of electrical systems in modern times. Another scientist who influenced contemporary technology is Joseph Henry, who developed the telegraph. Likewise, the acclaimed scientist Hans Christian Ørsted discovered electromagnetism, which broadened the range of scientific possibilities. Despite the eminence of Tesla, Henry,…

Jacob Schuster Comparing and Contrasting Michael Faraday and Hans Christian Orsted Michael Faraday and Hans Christian Oersted were both Chemists and Physicists in the 1800’s. They both discovered the connection between magnetism and electricity. This paper will give backgrounds on both Faraday and Oersted and will compare and contrast their works. Michael Faraday was born in London on September 22, 1791. He was the first person to produce an electric current from a magnetic…
