Name the two acids that are present in acid rain.

Explanation

Acid rain contains `H_(2)CO_(3). HNO_(3)` and `H_(2)SO_(4). H_(2)CO_(3)` is formed by the dissolution of `CO_(2)` of the air in which the water vapour present.
`CO_(2) + H_(2)O rarr H_(2)CO_(3)`
Forest fire and lighting are the natural sourc of nitric oxide `(NO)`. Nitrogen oxides are also produced by combusion engines, aircraft furnaces, incinerators, industrial plants.
Nitric oxide slowly reacts with atmospheric air and produce `NO_(2).NO_(2)` dissolves in water to form `HNO_(3)`.
`3NO_(2) + H_(2)O hArr 2HNO_(3) + NO`
Sulphur oxides are produced by the burning of fossil and in extraction of metals from their sulphide ores etc. Sulphur dioxide also produces sulphuric acid in the similar way.
`SO_(2) + H_(2)O overset("Soot particles")underset("Metal oxides")rarr H_(2)SO_(4) + [O]`
