... limits and how much sulphur dioxide they emitted in 1980, 1990, 1994, 1995, and 1996. It also contains sulphur emissions from major sources from four Canadian provinces as well as sulphur dioxide emissions from electric power generators in three Canadian provinces. There are also some interesting questions and answers and facts are included also. This information was organized from various websites. It also contains information from a newspaper article about a new monitoring site for acid rain in Irish Cove located in Cape Breton, Nova Scotia. ACID RAIN The atmosphere, unpolluted, is the means of life on earth. It is a thin layer of gases which surrounds ...

... many that a method of study was needed. The study of oceans was named oceanography. Density, salinity, and temperature are very important concepts in the study of oceanography. The salinity and temperature of the water influence its density, and the differences in density are the major factor in understanding the formation of currents and the positions of water masses in the sea. In addition, temperature and salinity play major roles in influencing the distribution of plants and animals. The sediments of the sea floor may be divided into lithogenous, hydrogenous, biogenous, and cosmogenous sediments. Lithogenous sediments are the major sediments on the ...

... of butane gas." Hemiparesis is when half of a person's body is paralyzed. Through reactions alkanes can be transformed into chloroform. This has been shown to accumulate in lungs of swimmers after they swim for extended periods of time. As mentioned above chloroform can be produced which can be used for anesthesia. Also dichloromethane, or paint stripper and 1,2-dichloroethane which is a dry cleaning fluid. Here is a sample reaction where a halogen replaces a hydrogen. CH4(g) + C12(g) ----> CH3Cl(g) + HCl(g) There are many uses for alkanes, for instance: Propane is used in gas grills, butane is used in cigarette lighters, through various react ...

... the idea that the continents moved for several reasons. Ignorance and strong religious beliefs played a part in this, but it was mainly rejected because of the lack of a good explanation for the movement of the continents. Wegener's theory for the movement of continents was called continental drift. This was not believable at the time because there was no way the continents could move through the rigid ocean floor. During WWII, people started to explore the ocean floor and discovered evidence that would prove Wegener's ideas about land movement. The most interesting feature of the ocean was the ridges running along the ocean floor. It was discovered that e ...

... carbon dioxide, and other gases) trap some of the energy that leaves, botteling heat like the glass panels of a greenhouse. Without this natural "greenhouse effect," temperatures would be alot lower than they are now, and life like today would not work. Instead, thanks to greenhouse gases, the earth's average temperature is better, 60°F. But, problems may happen when the amount of greenhouse gases increases. Since the beginning of the industrial revolution, great amounts of carbon dioxide have increased nearly 30%, methane concentrations have almost doubled, and nitrous oxide concentrations have risen about 15%. These increases have made the h ...

... kilometers up in the stratosphere called the ozone layer. This layer protects the inhabitants of earth by reflecting much of the suns harmful ultra violet (UV) rays. Without this layer above us, many living things including humans could not survive. The ozone layer is currently depleting and the reason for this is believed to be caused by a few things. Deforestation, fertilizer use and fuel combustion are minor contributors to this problem while chemicals such as chloroflourocarbons (CFCs), halons, carbon tetrachloride, methyl chloroform, methyl bromide and hydrochloroflourocarbons (HCFCs) are the major contributors to the deterioration of the ozone layer. ...

... which can lead to infertility if left untreated. 75% of women with the disease show no symptoms. In those that do, it is usually a yellow discharge from the urethra, painful urination, or painful sex. ½ of all cases of pelvic inflammatory disease, which leads to an ectopic pregnancy in pregnant women, is caused by . Ectopic pregnancy is the leading cause of death of pregnant teens in the inner city and poor neighborhoods. also causes conjunctitis. This is a swelling of the eyes which can lead to blindness. The bacteria also can lead to pneumonia. Although it is the most easily treated STI, most people in danger won’t get checked until complications show, ...

... damaging national problem. I don’t think people are fully aware of the serious consequences that acid rain have on many different factors. For one, Acid rain causes acidification of lakes, streams, and other bodies of water. Because many lakes and streams suffer from chronic acidity (a condition which water has a constant low pH level) this makes them susceptible to acid rain because of their limited ability to neutralize acidic compounds. This results in many lakes and streams being completely dead of fish and all other living things. Acid rain also greatly contributes to forest degradation, even more so to high-elevated trees, it also impairs the tree growth. A ...

... or . HISTORY OF ALCHEMY: From an early period the Egyptians possessed the reputation of being skillful workers in metals and, according to Greek writers, they were conversant with their transmutation, employing quicksilver in the process of separating gold and silver from the native matrix. The resulting oxide was supposed to possess marvelous powers, and it was thought that there resided within in the individualities of the various metals, that in it their various substances were incorporated. This black powder was mystically identified with the underworld form of the god Osiris, and consequently was credited with magical properties. Thus there grew up i ...

... in Geneva. While traveling between Italy, France, and England, Boyle was being tutored in the polite arts, philosophy, theology, mathematics, and science. As the years went by, Boyle became more and more interested in medicine. His curiosity in this field led him to chemistry. At first Boyle was mainly interested in the facet of chemistry that dealt with the preparation of drugs, but soon he became genuinely interested in the subject and started to study it in great detail. His studies led him to Oxford where he joined such scientists as John Wilkins and John Wallis. Together in 1660, they founded the Royal Society of London f ...
