    • 3 Pages

    This article, though a few years old, gives a brief background over how oil is formed, where it is formed, and the importance of offshore drilling. The first point the articles makes is to deter from what once was believed that oil is formed from biodegrading dinosaurs to the fact oil comes from microscopic organisms at sea. Scientist estimate that each drop of sea water contain millions of life forms and after several millions of years these microorganisms get compacted deep into the…

    reactions happening all the time and you don’t even know it. Some of the ways that the elements are distributed throughout the body are in the bones, blood, metabolism, genetics, and even diseases. In fact, the human body is composed of 65% Oxygen, 18% Carbon, 10% Hydrogen, 3% Nitrogen, 1.5% Calcium, and in smaller amounts of several other elements. Bones make up the skeleton of the human body. They are composed of a collagen rich mixture of calcium and phosphate, which are both elements…

    is a reducing agent that is able to reduce ketones and aldehydes. In this case, camphor, which contains a ketone, was reduced with sodium borohydride. Reduction of a carbonyl with sodium borohydride occurs when the hydride ion adds to the carbonyl carbon, breaking the C=O bond and creating a new C-H bond. When the reduction occurs, the hydride transfer will occur on the less hindered side of the carbonyl group. This addition will usually create the more hindered alcohol but will generally create…

    Reduction involves increasing the number of carbon hydrogen bonds by adding hydrogen across a double or triple bond which results in an increase in electron density at the carbon atom. Organic functional groups containing double and triple bonds which undergo reduction are unsaturated. The reduction of the double bond by addition of hydrogen atoms results in the product being fully saturated. Metal hydride reducing agents that have different reactivities toward specific functional groups are…
