1.	The sculptures and monuments get demaged due to acid rains. Usage of scrubbers, containing lime, in industries decreases the percentage sontent of the major air pollutants that constribute to acid rain. The haracterstic reaction involved in the scrubber is ,
Answer» neutrazation oxidation reduction combination followed by decompositon. Solution :Marble is MADE of `CaCO_(2)` which gets dissolved when it reacts with acids like `H_(2)SO_(4)` or `HNO_(3)` of acid rains. The major POLLUTANTS which contribute to acid rain `NO_(2)" and "SO_(2)` are relesed into the atmosphere. The `NO_(2)" and "SO_(2)` percentage content in the atmosphere can be decreased by using equipment like scrubbers. It a scrubber, powdered `CaCO_(3)` is taken which undergoes decomposition to give CaO. This quick LIME cmbines with `SO_(2)" to form "CaSO_(3)` which is removed as slurry. `underset("Base")(CaO)+underset("acid")(SO_(2))toCaSO_(3)darr` Hence it is a neutralization reaction.
