Which of the following on burning in air contributes to acid rain?
Answer Details
Sulphur, when burned in air, contributes to the formation of sulphur dioxide gas (SO2). This gas, when released into the atmosphere, can react with water and oxygen to form sulphuric acid (H2SO4), which is a major contributor to acid rain. Therefore, sulphur is the correct answer.
