Question

Oxides of ___, ___ and___ in combination with water vapour forms Acid rain.

• A. Sulphur, Nitrogen and Carbon
• B. Phosphorous, Nitrogen, and Carbon
• C. Sulphur, Nitrogen, and Phosphorus
• D. Sulphur, Chlorine, and Nitrogen

Answer 1

The correct option is A Sulphur, Nitrogen and Carbon

Fossil fuels contain carbon, nitrogen and sulphur. When they are burnt, they release them as different oxides of carbon, nitrogen and sulphur. These oxides react with the water present in the atmosphere, making airborne sulphuric, carbonic and nitric acids. They precipitate on earth in the form of rain, snow or fog with high levels of acids.
