Question

1. Define Acid rain?
2. What is Crystallization?​

Answer 1

Answer:

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the 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.

Explanation:

What is crystallization? Crystallization is defined as a process by which a chemical is converted from a liquid solution into a solid crystalline state.

Answer 2

Answer:-

• 1.Acid rain results when 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. These then mix with water and other materials before falling to the gground.
