Sulfur; nitrogen.
Explanation:
Acid precipitation results when sulfur and nitrogen compounds react with water in the atmosphere.
This acid precipitation is also known as acid rain and it is typically caused by the chemical reaction between sulfur oxide and nitrogen oxide which are released into the air as a result of burning fossil fuels, with water and other chemical elements present in the atmosphere.
Generally, acid precipitation (acid rain) usually have a pH of about 5.1 or below and as such, it is very acidic nature i.e possessing a large amount of hydrogen ions.
Hence, acid precipitation (acid rain) when washed to the earth has negative or harmful effects on various living and non-living organisms such as animals, plants, cars, buildings etc.
