Question

Power plants release sulfur dioxide and nitrogen oxides into the atmosphere, where they combine with water vapor to form: A) acid precipitation B) ozone C) particulates D) carbon minoxide

Answer 1

Power plants release sulfur dioxide and nitrogen oxides into the atmosphere, where they combine with water vapor to form A) acid precipitation.
Acid precipitation is usually rain which is acidic from high levels of hydrogen ions (low pH).

Answer 2

Answer is (A) - Acid precipitation.

Precipitation is falling down of condensed atmospheric water to the ground. The form of precipitation can be rain, snow and fog.

Acid precipitation means the falling down of condensed atmospheric water with acids. The pH of acid precipitation is lower than 5.5. Sulfuric dioxide and nitrogen oxides react with water vapor and cause acid rain precipitations.

SO₂(g) + H₂O(g) → H₂SO₃(aq)

2NO₂(g) + H₂O(g) → HNO₂(aq) + HNO₃(aq)
