Question

Acid rains are produced by

• A. excess emissions of ${\mathrm{NO}}_2$ and ${\mathrm{SO}}_2$from burning fossil fuels
• B. excess production of ${\mathrm{NH}}_3$ by industry and coal gas
• C. excess release of carbon monoxide by incomplete combustion
• D. excess formation of ${\mathrm{CO}}_2$ by combustion and animal respiration

Answer 1

The correct option is A excess emissions of ${\mathrm{NO}}_2$ and ${\mathrm{SO}}_2$from burning fossil fuels

${\mathrm{NO}}_2\mathrm{and}{\mathrm{SO}}_2$ from industries and vehicular emissions, react with moisture in the atmosphere to produce ${\mathrm{HNO}}_3\mathrm{and}{H}_2{\mathrm{SO}}_4$which precipitate as acid rain.
