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

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.
