HELP Which of the following substances is a major component in acid rain? A) KOH
B) NH3
C) SO2
D) NaOH

I believe the answer is (C) SO2.

SO2 is known as sulfur dioxide.

The below information about acid rain and SO2’s involvement is from epa.gov:

“Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground.”

Hope this helps!
