Which of the following gas is responsible for acid rain?
- A Sulphur dioxide and nitrous oxide
- B Sulphur dioxide and carbon monoxide
- C Sulphur dioxide and carbon dioxide.
- D Sulphur dioxide and nitrogen oxide
Answer & Solution
Correct Answer
(D) Sulphur dioxide and nitrogen oxide
Step-by-step Solution
Detailed explanation
Acid rain is primarily caused by the emission of sulphur dioxide (\(SO_2\)) and nitrogen oxides (\(NO_x\)). These gases react with water vapor and other chemicals in the atmosphere to form sulphuric acid (\(H_2SO_4\)) and nitric acid (\(HNO_3\)), which then fall to the ground as…
