Question 5
5. CFC's break down
Ozone
carbon dioxide
Oxgygen
nitrogen

Answer 1

C: Oxygen

Step-by-step explanation:

When they are exposed to strong ultraviolet light, CFCs finally break down to release lone chlorine atoms with an unpaired electron. These chlorine atoms are highly unstable and react with ozone to break it down into oxygen through a type of chain reaction.

Answer 2

ozone. CFCs drift slowly upward to the stratosphere, where they are broken up by ultraviolet radiation, releasing chlorine atoms, which are able to destroy ozone molecules.
