Question

What is ozone layer?can we call the breaking down of ozone a chemical change​

Answer 1

Answer:

Chemistry of Ozone Depletion

Explanation:

Chlorine is able to destroy so much of the ozone because it acts as a catalyst. Chlorine initiates the breakdown of ozone and combines with a freed oxygen to create two oxygen molecules. After each reaction, chlorine begins the destructive cycle again with another ozone molecule.

Answer 2

Answer:

The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere around 15–30km above the earth's surface. It covers the entire planet and protects life on earth by absorbing harmful ultraviolet-B (UV-B) radiation from the sun.

Explanation:

The destruction of ozone layer is chemical change. The chemical equation for destruction of ozone can be written as: Cl + O3 → ClO + O2 – The chlorine atom changes an ozone molecule to ordinary oxygen. As during the reaction, ozone molecules destroy and oxygen molecules form. So new chemical substances are formed by consuming the starting material hence it is a chemical change.Read more on Sarthaks.com - https://www.sarthaks.com/104526/is-breaking-of-ozone-chemical-change
