Minorities have had many contributions to science and chemistry. A few of these minorities are George Washington Carver, Marie Curie, Lloyd Hall, James Harris, Mario Molina, Baruj Benacerraf , Luis Federico Leloir, and César Milstein. An African-American born to slave parents, George Washin...

Many in the world of science do not succeed as prominent individual considering it is a tough field not only to achieve in but to maintain an identity. Mario J. Molina was someone that prospered as a minority and Nobel Laureate in this particular field. Mario was a Mexican American chemist, born...

Antoine-Laurent Lavoisier was born on Aug. 26, 1743. He grew up the oldest child in his family in Paris, France, and a product of the bourgeoisie lifestyle. His father was a well-off attorney who followed the family tradition of practicing law. Antoine's mother died when he was just a boy, bu...

Aluminum is slivery white, nonmagnetic, no sparking, and extremely light weight. Among all elements Aluminum is 2nd among metals in malleability and 6th in conductibility. At room temperature this metal is a solid. Aluminum's symbol is Al, its atomic number is 13, and it has a mass of 27.0. ...

MTBEMethyl Tertiary Butyl Ether. The word sounds like it's foreign. It might even sound like it is out of that nerd in highschool's chemistry book, but it is becoming as common as wildfires in Redding. Until about seven years ago, when it was first introduced into our lives, many American's had n...

Year 11 Chemistry Unit 1 POLYETHENE-ain't it choice! word count : 1131 Polyethene also known as polyethylene or polythene, was the first of the polymers to be discovered. Polyethene is a polymer produced by reacting oxygen and ethene, in this reaction the small ethene molecules attach t...

Sterling Lake Introduction We were interested in the biotic and a biotic factor in the aquatic environments of Sterling Lake in Lake County, IL. We examined water chemistry by using the Hach kit spectrometer to measure the chemical components dissolved in water. We tested a particular form of ...

For many years now, scientists have researched and test the affects of air pollution. It has already been proven that pollution and the chemical substances affect a person's health and well being. There are a lot of things pollute the air, including ourselves and what we do. Pollution is basi...

Acid rain is rain that is more acidic than normal. Acid rain is a complicated problem. Primarily caused by air pollution, acid rain\'s spread and damage involve weather, chemistry, soil, and the life cycles of plants and animals on the land and in lakes and streams. This form of air pollution is ...

A Review of Oxidative Stress and Antioxidants Introduction Oxidants such as super oxide, a free radical form of oxygen gas, hydrogen peroxide, and free radical hydroxide are molecules that can commence chain reactions in a cell and cause damage along the way. A free radical is any molecule with...

Electron Pair Repulsion Theory: The electron pair repulsion theory states that the electron pairs in the valence energy level of an atom repel each other, and therefore are arranged as far apart as possible. For example, H2O:Due to this theory, different molecules with different amounts of pairs of...

Themelting point of Bromine is -7 deg.C and the boiling point is 58 degC with a relativedensity of 3.1. Bromine is a volatile dense mo...

In this paper I will describe the molecular structure and the chemical properties of water. Also I will discuss the importance of water to living organisms and the effects of acid rain on our environment. Water, as a molecule is a bent molecule and this characteristic makes it a very polar. W...

Acid Rains Scientific evidence has shown that atmospheric deposition of sulfur and nitrogen compounds can harm ecosystems. Title IV of the Clean Air Act Amendments of 1990 (CAAA or the Act) addresses the problem of such effects by mandating reductions in emissions of sulfur and nitrogen oxides, t...

One Of Life's Great Proteins V HemoglobinIntroductionHemoglobin is a protein, which is one of the four basic biological molecules of life. Proteins have many functions and are versatile molecules. They are important for building and repairing cells and tissues and also as enzymes that are used in ...

Human interference in biogeochemical cycles:Causes, Consequences & SolutionsIntroductionAll forms of life on Earth are involved in and dependent on the on the interaction among the atmosphere, oceans and the crusts through a variety of biogeochemical cycles. A biogeochemical cycle is defined as the ...
