atmospheric concentrations of co2

Atmospheric Pollutants - Many of the air pollutants are naturally present in the atmosphere in low concentration. They become pollutants when their concentration is relatively high. For example, SO 2 is considered as pollutant when its concentr..

In the atmosphere, the concentration of carbon dioxide ranges from .03 to .04 %. However, it is found that 0.1% of carbon dioxide in the atmosphere increases the rate of photosynthesis significantly. This is achieved in the gree..

Earth is an abundant source of material. Man has intensively studied the properties of these materials extensively and found new methods of using them. The air we breathe, the water we drink, stones and rocks, almost everything that is around us, are all useful to man for some purpose or the ..

Contamination of air with harmful toxic gases, smoke and particulate matter (e.g., dust etc.) is called air pollution. The substances that cause pollution are called pollutants. Combustion of fossil fuels is one of the main causes of pollution of the atmosphere in our cities and towns. Fo..

>It is manufactured by the Ostwald's Process by the reaction of ammonia and air in presence of platinum as catalyst at 700-800 o C. Nitric acid is colourless in pure form. Commercial nitric acid is yellowish due to the presence of dissolved nitrogen dioxide. Basic oxide + nitric..
