Effects Of Acid Rain Sulfur Dioxide
1,028 words"Acid Rain, " or more precisely acidic precipitation, is the term used to describe rainfall that has a pH level of less than 5. 6 -- a pH of 7 being neutral. This form of air pollution is currently a subject of great controversy because of the damage it does tot he environment and property worldwide. For the last ten years, this occurrence has brought destruction to thousands of lakes and streams in the United States, Canada, and parts of Europe. It also leads to the deterioration of buildings a...

Nitrous Oxide Liquid Nitrogen
551 wordsNitrogen was isolated by the British physician Daniel Rutherford in 1772 and recognized as an elemental gas by the French chemist Antoine Laurent Lavoisier about 1776. Properties Nitrogen is a colorless, odorless, tasteless, nontoxic gas. It can be condensed into a colorless liquid, which can in turn be compressed into a colorless, crystalline solid. Nitrogen exists in two natural forms of isotopes, and four radioactive isotopes have been artificially prepared. Nitrogen melts at - 210. 01 C (- 3...

Role In The Nitrogen Cycle Nitrogen From The Atmosphere Tree
374 wordsThe nitrogen cycle is a complex biological cycle involving the recycling of usable nitrogen. If this cycle ceased to occur, all forms of life on the planet would die. All life forms, including humans, use nitrogen in compounds called amino acids. These amino acids then act as building blocks for proteins. Nitrogen, in fact, is the most abundant element in the atmosphere. Most organisms are unable to use this nitrogen from the atmosphere and rely on the nitrogen in the soil. The cycle consists of...

Nitric Acid Scientific American
825 wordsChemistry Connections of nitrogen - saltpeter, nitric acid, ammonia - were known long before invention of nitrogen in a free condition. In 1772 D. Rutherford, burning phosphorus and other substances in a glass bell, has shown that the gas remaining after combustion does not support breath and burning. He named it suffocating air. In 1787 A. Lavoisier has established, that the "vital" and "suffocating" gases included in air, are simple substances, and has offered the name "nitrogen." In 1784 G. C...

Low Birth Weight Nitrogen Dioxide
1,290 wordsAir Pollution Air pollution is one of the most dangerous problems of our times. Problems caused by pollution can be local and minor because of the Earth's own ability to absorb pollutants. The industrialization of society, the introduction of motorized vehicles, the explosion of the population are factors sharpening the growing air pollution problem. Carbon monoxide, nitrogen oxides and particulate matter belong to pollutants found in most urban areas. These pollutants are dispersed throughout t...

Petri Dishes Flowering Plants
3,855 wordsIs there an effect on Rhizobium bacteria by changing its pH? Steve Lincoln Period 3 12 / 7 / 98 Question What are the effects of varying pH levels on Rhizobium bacteria, and can a pH resistant Rhizobium culture be grown? Hypothesis Alterations of the balanced habitat such as the change of pH levels can drastically alter the life of bacteria and can directly affect chemical reactions of enzymes released by the bacteria. Using this information the change in pH will have an effect on the Rhizobium ...

Plant Growth Harmful Effects
2,117 wordsMany questions have Fertilizers Fertilizers Many questions have been raised concerning the use of fertilizers, why plants require them, and about the benefits they bring. Fertilizers have a significant effect on humanity, as they form the basis of food production. The addition of fertilizers assists enrichment of soil fertility and corrects nutrient deficiencies so that plants can grow more healthily, provide crops and food for people, and increase food production. In this way, fertilizers are s...

Nitrogen Oxides Nitrogen Dioxide
1,758 wordsGifted Chemistry IB Alternative Untitled Gifted Chemistry IB Alternative Assessment Photochemical Smog Historically, the term smog referred to a mixture of smoke and fog, hence the name smog. The industrial revolution has been the central cause for the increase in pollutants in the atmosphere over the last three centuries. Before 1950, the majority of this pollution was created from the burning of coal for energy generation, space heating, cooking, and transportation. Under the right conditions,...
