The February 17, 1992 edition of time magazine's cover story started like this: The world now knows that danger is shining through the sky. The evidence is overwhelming that the earth's stratospheric ozone layer-our shield against the sun's hazardous ultraviolet rays-is being eaten away by man made chemicals far faster than any scientist had predicted. Now this is interesting rhetoric, but there is no evidence here to support this article at all. Where are the facts? The studies? What I will
Chemistry Essay - Water
Chemistry Essay - Water
Chemistry Essay - Water Water covers nearly three quarters of the earth and is present in air, land and, of course, sea. Most living things contain a large proportion of water, the human body is about 60% water. Water is essential for life as we know it. The physical states of water are determined by the structure of its molecules, which in turn is affected by temperature. As ice melts, its rigidly arranged molecules move more and more freely. As water is heated, the molecules move even faster
Magnesium

Vanadium Atomic Number: 23 Atomic Symbol: V Atomic Weight: 50.9414 Electron Configuration: -8-11-2 History (Scandinavian goddess, Vanadis) Vanadium was first discovered by del Rio in 1801. Unfortunately, a French chemist incorrectly declared that del Rio's new element was only impure chromium. Del Rio thought himself to be mistaken and accepted the French chemists's statement. The element was rediscovered in 1830 by Sefstrom, who named the element in honor of the Scandinavian goddess, Vanadis, b
Chemical Reactions
Chemical Reactions
Chemical Reactions Chemical reactions are the heart of chemistry. People have always known that they exist. The Ancient Greeks were the firsts 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 named Georg Ernst Stahl was the first to postulate on chemical reaction, specifically, combustion. He said that a substance called phlogiston escaped into the air from all substances dur
Aversive Conditioning
Aversive Conditioning
Aversive Conditioning Aversive conditioning is a manufactured negative response to certain things, much like the operant conditioning developed by Skinner. The contingent behavior is behavior that, when performed, results in the delivery of specific consequences or reinforcers. This article described the measures taken to make coyotes stop wanting to kill lambs for food. The authors’ contention is that it may be possible to reconcile the desires of both ranchers and conservationists. The latte

Cystic Fibrosis Cystic fibrosis is an autosomal recessive trait on chromosome 7. This disorder affects chloride transport resulting in abnormal mucus production. This lifelong illness usually gets more severe with age and can affect both males and females. Symptoms and severity differ from person to person. Cystic fibrosis is the most common fatal inherited disease among whites and the major cause of chronic lung disease in children. 50% of people are expected to live to be 30, but a majority di
Salt Pollution
Salt Pollution
Salt Pollution As awareness for pollution increases, other forms of pollution are defined. Almost everyone knows about toxic waste and carbon dioxide pollution, but not many people have heard of salt pollution. Salt pollution has been on the increase since the evolution of the automobile. With more pressure on government agencies to keep the highway clear and safe, an increase in the use of salt has developed. It is important to understand why salt is used and how it work as well as the environm

This report will go into depth on how the food we eat gets into our cells, and how the waste products that we produce get out of the body. Also, the unicellular organism Paramecium will be compared with a human being, in terms of all of the above factors. Dietary Nutrients The chief nutrients in a diet are classified
Kidneys
Kidneys
Kidneys In vertebrates, kidneys are the two major organs of excretion. Excess water, toxic waste products of metabolism such as urea, uric acid, and inorganic salts are disposed of by kidneys in the form of urine. Kidneys are also largely responsible for maintaining the water balance of the body and the pH of the blood. Kidneys play important roles in other bodily functions, such as releasing the erythropoietin protein, and helping to control blood pressure. Kidneys are paired, reddish-brown, be
Chloroflourocarbons
Chloroflourocarbons
Chloroflourocarbons Chloroflourocarbons were discovered in the 1920's by Thomas Midgley, an organic chemist at General Motors Corporation. He was looking for inert, non- toxic, non-flammable compounds with low boiling points that could be used as refrigerants. He found what he was looking for in the form of two compounds: dichlorodifluoromethane (CFC-12) and trichloromonoflouromethane (CFC-11). In both compounds, different amounts of chlorine and fluorine are combined with methane, which is a co
