Vedclass · Answer

(A) The Taj Mahal is primarily composed of marble,which is $CaCO_3$ (calcium carbonate).$SO_2$ emissions from the Mathura refinery react with atmospheric moisture to form $H_2SO_4$ (sulphuric acid),leading to acid rain.This acid reacts with the calcium carbonate of the monument: $CaCO_3 + H_2SO_4 \longrightarrow CaSO_4 + H_2O + CO_2$.The resulting calcium sulphate $(CaSO_4)$ is a powdery,unstable substance that causes the marble to corrode and lose its luster,leading to the destruction of the monument.Therefore,both the Assertion and the Reason are correct,and the Reason provides the correct explanation for the Assertion.

$A$: Taj Mahal is being destroyed by $SO_2$ coming from Mathura refinery.
$R$: This converts $CaCO_3$ into unstable calcium sulphate.
