Question

CFC-12 can NEVER be exposed to ____.
1) Oxygen
2) Water
3) Sunlight
4) Heat

Answer 1

CFC-12 should never be exposed to oxygen, water, sunlight, or heat due to their contribution to ozone depletion.

Step-by-step explanation:

CFC-12, also known as trichlorofluoromethane, should never be exposed to oxygen, water, sunlight, or heat.

CFCs are stable compounds that can contribute to ozone depletion in the atmosphere.

When CFCs are exposed to UV light in the stratosphere, a chlorine atom is released from the molecule, which can then destroy ozone molecules.
