Acid Rain
Acid rain is a kind of air pollution. When coal, oil, or gasoline are burned, they release harmful gases into the air. These gases mix with the moisture that is always present in the air and form weak acids. Wind can carry the acidic droplets huge distances. Eventually, these droplets return to the ground as acid rain or as acid hail, snow, sleet, or even fog. Acid rain looks, feels, and tastes just like clean

Acid Rain
INTRODUCTION: Acid rain is a great problem in our world. It causes fish and plants to die in our waters. As well it causes harm to our own race as well, because we eat these fish, drink this water and eat these plants. It is a problem that we must all face together and try to get rid of. However acid rain on it's own is not the biggest problem. It cause many other problems

Chemical Warfare and Its Uses Chemical warfare is the use of natural and man-made toxic substances to incapacitate or kill an enemy. There are many different types of agents used in chemical warfare, some of which are mustard gases, nerve gases, psychotomimetic agents, tear gases, hydrogen cyanide, and arsines. All of which are very poisonous and lethal when exposed to humans in large amounts. Until the 20th century such warfare was primarily limited to starting

Distillation Andrea Pausma October 1, 2001 I. Introduction The process of distillation has been used by humans for years to create alcoholic beverages. Distillation is the process of boiling a pair of liquids with different boiling points and then condensing the vapors above the boiling liquid in an attempt to separate them. One might suspect that the mixed two liquids of different boiling points could be separated simply by raising the temperature to the lower

Acid Rain
Acid rain is a very big pollution problem in the world. It has killed fish and other aquatic life in many lakes and streams. It harms human health, disfigures monuments and erodes buildings, and, along with other pollutants, threatens forests. The story of acid rain can be compared to the plot of a science fiction movie. In the 1950s an invisible force begins to destroy lakes and rivers, killing trout and salmon. By the

Chemistry And Carbohydrates
The Chemistry of Carbohydrates The chemistry of carbohydrates most closely resembles that of alcohol, aldehyde, and ketone functional groups. As a result, the modern definition of a carbohydrate is that the compounds are polyhydroxy aldehydes or ketones. The chemistry of carbohydrates is complicated by the fact that there is a functional group (alcohol) on almost every carbon. In addition, the carbohydrate may exist in either a straight chain or a ring structure. Ring structures incorporate

Acid Rain
Acid rain is considered by many people to be one of the most serious environmental problems of our time. It is a global problem that is slowly eating away at our world. Angus Smith came up with the word acid rain when he wrote about pollution in England. Most rain is naturally acidic because of the carbon dioxide (CO2) in the air that dissolves with rainwater and forms a weak acid. This kind of acid

Acid Rain
Acid rain is one of the most dangerous forms of pollution on the Earth, and it is sometimes known as "the unseen plague," because it can go undetected for very long periods of time. Acid rain does not actually have to be in the form of rain, it can be any type of precipitation. It is not something to be taken lightly, as it is harmful during the time it precipitates and still affects

Cadmium is a chemical element in the periodic table that has the symbol "Cd" and atomic number forty-eight. It is a relatively rare, soft, bluish-white, toxic transition metal, cadmium occurs with zinc ores and is used largely in batteries. Cadmium is a common impurity in zinc, and it is most often isolated during the production of zinc. Zinc sulfide ores are roasted in the presence of oxygen converting the zinc sulfide to the oxide.
