Give reasons for the following. 1.Release of oxides of sulphur and nitrogen into the atmosphere should be reduced 2.Burning of dry leaves and wood should be avoided. 3.Plastic should not be disposed of into the water.

Answer:
Oxides of Sulphur and Nitrogen
We know elemental nitrogen is one of the major components of earth’s atmosphere. Thus, it will participate in many natural processes. It is responsible for the formation of nitrogen dioxide entering the atmosphere. The classic example of the formation of nitrogen oxides is by the chemical reaction of atmospheric nitrogen and oxygen during the thunderstorm.
The chemical reaction occurs in the presence of lightning to form the nitric oxide which further undergoes reaction with oxygen to form nitrogen dioxide. Oxides of sulphur and nitrogen are responsible for many natural phenomena.
Similarly, oxides of sulphur such as sulphur dioxide enter the atmosphere by natural processes such as volcanic eruptions. Moreover, oxidation of hydrogen and sulphide during organic matter decomposition process in the absence of air leads to the formation of sulphur dioxide.
Since many decades the natural processes based on oxides of sulphur and nitrogen have been taking place and there was a global balance of these gases in the earth’s atmosphere. However, lately many anthropogenic or human activities led to the increase in the amounts of the compounds more than the desired quantity.
Thus, it is causing an imbalance in the earth’s atmosphere and exerting detrimental effects. Thus the excess quantity of the gases makes it air pollutants. We will study the negative impact of oxides of sulphur and nitrogen when present in excess quantity than the permissible limit.
