Acid Rain is a type of air pollution‚ which is formed when oxides of sulfur and nitrogen combine with atmospheric moisture to yield sulfuric and nitric acids‚ which may then be carried long distances from a source before they are deposited by rain. This pollution may also take the form of snow‚ fog‚ or a dry form of precipitation. Acid rain is currently a subject of great controversy because of widespread environmental damage‚ for which it has been blamed‚ including eroding structures‚ injuring crops

Clays are one of the important natural materials‚ which have been examined for catalytic applications. Clays are characterized by a layered structure and hence they are slippery when wet. They are broadly classified as cationic or smectite type (having layer lattice structure in which two-dimensional oxyanions are separated by layers of hydrated cations) and anionic or brucite type (in which the charge on the layer and the gallery ion is reversed complimentary to smectite type). Anionic clays are

Causes Acid Rain? {2} {2} Acid rain caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into air. These substances can rise very high into the atmosphere‚ where they mix and react with water‚ oxygen‚ and other chemicals to form more acidic pollutants‚ known as acid rain.{2} Sulfur dioxide and nitrogen oxides dissolve very easily in water and can be carried very far by wind. As a result‚ the two compounds can travel long distances where

The air bag is in front of the passenger seat inside the dashboard. Once the vehicle gets into a crash the air bag pops out. The air bags are filled nitrogen gas. Hazardous sodium metal is also produced with the nitrogen so the potassium nitrate adapts with the sodium to make the hazardous sodium oxide less harmless. The uses of the stoichiometry

Admittedly‚ with the popularity of cheap air travel‚ more consumption of fuel may lead to pollution of surroundings and degradation of air quality. Pollutants (e.g.‚ sulfur dioxide and nitric oxide) will damage our living circumstance. However‚ any transport tools have fuel consumption. The authorities have taken measures to alleviate this problem. To sum up‚ although there may be some fuel depletion‚ taking the clear benefits-- economical
