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...

Respiration is the process by which oxygen is delivered to cells and body systems for use. It consists of levels, several of which are breathing, internal respiration, and external respiration. Breathing is the process by which air is inhaled and exhaled through the mouth. External respiration is th...

Antoine Lavoisier (1743-1794)Antoine-Laurent Lavoisier (lah vwah ZYAY) was one of the best-known French scientists and was an important government official. His theories of combustion, his development of a way to classify the elements and the first modern textbook of chemistry led to his being known...

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...

When people think of hydrogen, outside the studying of a chemistry class or something to that effect, thinks immediately of the hydrogen bomb. This situation is obvious a big image problem. Thanks to new technology, hydrogen has escaped the imagine of the unbearable to other more economical though...

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...

Chemical reactions are the heart of chemistry. People have always known that they exist. The Ancient Greeks were the first to speculate on the composition of matter. They thought that it was possible that individual particles made up matter. Later, in the Seventeenth Century, a German chemist na...

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 ...

The first way that food decays is Putrefaction. In this way, it is when biological decomposing of organic matter, with ill-smelling and tasting products. In this type of decomposition there is no oxygen present. The first step to the Putrefaction, a type of decomposition, is the material is decomp...

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...

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...

Fluorine Fluorine is in many of the items we use everyday, such as water, toothpaste, and air conditioners. The name fluorine came from the Latin word fluo, which means, "flowing". Fluorine is the 13th or 14th most abundant element on earth. It is classified as a halogen on the per...

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...

Joseph Priestly was an English chemist and a natural philosopher. He was born in Fieldhead, England on March 13, 1733 and died on February 6, 1804. He was the oldest of six children (three brothers and two sisters). His mother was a farmer's daughter and his father was dresser and finisher of cloth....

For years ever since most of the world has been industrialized, the effects of pollution have plagued nations alike. Acid rain is one of the largest contributors to this industrialized form of pollution. Throughout this report an explanation of the devastating effects to the environment caused by ...

Society has been widely addressed with the many problems that we arehaving in our environment today. A major problem is that of CFCs. CFCstands for Chlorofluorocarbons which are found in many of the aerosol spraycans. In December of 1973, Rowland and Molina discovered that CFCs candestroy the ozo...
