Question

which of the following gases are main contributors to acid rain a- carbon dioxide and carbon monoxide b- sulphur dioxide and carbon monoxide c- sulphur dioxide and nitrogen dioxide d- sulphur dioxide and nitrous oxide​

Answer 1

Explanation:

sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids.

Answer 2

The main contributors to acid rain are Sulphur dioxide and Nitrogen dioxide. So, option 'C' is correct.

• Acid rain is the natural phenomenon when acid comes out in the form of rain because of the presence of the high amount of oxides of Sulphur and Nitrogen in the atmosphere.
• Acid rain is mainly of two types wet composition and dry composition.
• The former includes any form which will remove these harmful chemicals from our atmosphere and brings them to the surface of Earth, while the latter includes when these chemicals stick with dust and small particles and cause harm to us.

Hence, The main contributors to acid rain are Sulphur dioxide and Nitrogen dioxide. So, option 'C' is correct.
