What happens when CFC or HCFC molecules get in the
stratosphere & free atoms of Chlorine are set free? -
Answer-These atoms attack Ozone Molecules causing the
formation of Chlorine Monoxide (CLO), after colliding with
another Ozone Molecule, causes 2 Oxygen (O2)
molecules to be made & leaving an atom of chlorine to act
as "Free Agent" starting the process over until 100,000
molecules of Ozone are destroyed by just one atom of
chloride.
