8. what gas forms ozone when nitrogen oxides and hydrocarbons react? a. carbon dioxide b. argon c. oxygen d…

Brief Explanations:

When nitrogen oxides and hydrocarbons react in the presence of sunlight, they cause a series of chemical reactions in the atmosphere. Oxygen molecules ($O_2$) are broken apart and oxygen atoms ($O$) combine with oxygen - containing molecules to form ozone ($O_3$). So the gas that is involved in the formation of ozone in this reaction is oxygen.

Answer:

c. Oxygen
