Question

the following is a chemical reaction for ______ with ozone.
clo + bro → cl + br + o2
cl + o3 → clo + o2
br + o3 → bro + o2
a. chlorofluorocarbons
b. halons
c. uv radiation
d. none of the above

Explanation:

Halons contain bromine - containing compounds. In the given reactions, bromine - containing species (BrO and Br) are involved in the reactions with ozone. Chlorofluorocarbons mainly release chlorine atoms that react with ozone but do not involve bromine in the way shown here. UV radiation is an energy source for ozone - related reactions but is not a reactant in these specific reactions.

Answer:

B. halons
