Detailed explanation-1: -Sulphur dioxide and nitrogen oxide are the principal chemicals for acid rain.

Detailed explanation-2: -Acid rain is caused by the release of sulfur dioxide and nitrogen oxides into the atmosphere, where they react with water, oxygen, and other chemicals to become sulfuric and nitric acid respectively.

Detailed explanation-3: -Acid rain is one way in which rocks can be chemically weathered. It can harm forests and crops, damage bodies of water, and contribute to the damage of statues and buildings.

Detailed explanation-4: -Power plants release the majority of sulfur dioxide and much of the nitrogen oxides when they burn fossil fuels, such as coal, to produce electricity. In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.

Detailed explanation-5: -Chemical weathering describes the process of chemicals in rainwater making changes to the minerals in a rock. Carbon dioxide from the air is dissolved in rainwater, making it slightly acidic. A reaction can occur when the rainwater comes into contact with minerals in the rock, causing weathering.
