Answer
Sulfur dioxide and nitrogen oxides
Explanation
Acid rain is formed when sulfur dioxide (SO2) and nitrogen oxides (NOx) are released into the atmosphere and react with the water, oxygen, and other chemicals to form sulfuric and nitric acids. These compounds then mix with rain, resulting in acid rain. These pollutants may come from natural sources, such as volcanoes, or man-made sources, such as the burning of fossil fuels. Therefore, sulfur dioxide and nitrogen oxides are the substances that dissolve in rain to form acid rain.
