The chlorine freed from the cfc acts as a catalyst and transforms in the into elemental oxygen. it is estimated that a single chlorine atom can destroy up to 1 million ozone molecules per second. a) nitrogen b) oxygen c) ozone d) radon

The answer is Oxygen. Oxidizeris a powerful, it deodorizes water and kills germs at concentrations of 1 part per million. At even lower concentrations in air it causes coughing, chest pain, and eye irritation.  This reaction occur over and over again, let a single atom of chlorine to act as a catalyst, it will affects many molecules of ozone. Experiments show its molecular structure exhibits resonance, as the oxygen-oxygen bonds are both identical. For ten points, identify this poisonous blue gas, whose molecules each contain three atoms.

helicase, i think thats it

idk im sorry.
