Question

Identify the elemental gas present in acid rain.

(a) Sulphur dioxide (b) Carbon (c)Nitrogen (d)Oxygen​

Answer 1

Answer:

Acid rain is occurred when sulfur dioxide and nitrogen oxide come together in atmosphere carried by air currents

Answer 2

Answer:

(a) Sulphur dioxide is the elemental gas present in acid rain.

Explanation:

• When Sulphur dioxide ($SO_{2}$) and nitrogen oxides ($NO_{X}$) are released into the atmosphere and carried by wind and air currents, acid rain occurs. Sulfuric and nitric acids are formed when $SO_{2}$ and $NO_{X}$ combine with water, oxygen, and other molecules.

• Acid rain is mostly composed of sulfuric acid ($H_{2} SO_{4}$), nitric acid ($HNO_{3}$), and carbonic acid ($H_{2} CO_{3}$).

• Sulfur dioxide and nitrogen oxide are the two powerful chemicals found in acid rain. These two gases react with rainwater and oxygen in the atmosphere, resulting in a chain reaction.
