Vedclass · Answer

(A) . Nitrogen oxides $(NO_x)$ react with water and oxygen to form nitric acid,leading to acid rain: $4 NO_{2(g)} + O_{2(g)} + 2 H_2O_{(\ell)} \rightarrow 4 HNO_{3(aq)}$. Thus,$A-IV$.$B$. Methane $(CH_4)$ is a potent greenhouse gas contributing to global warming. Thus,$B-III$.$C$. Carbon dioxide $(CO_2)$ dissolves in rain water to form carbonic acid,which lowers the $pH$ to approximately $5.6$: $H_2O_{(\ell)} + CO_{2(g)} \rightleftharpoons H_2CO_{3(aq)} \rightleftharpoons H^+_{(aq)} + HCO_{3(aq)}^-$. Thus,$C-II$.$D$. Phosphate fertilizers runoff into water bodies,causing nutrient enrichment and leading to Eutrophication. Thus,$D-I$.

List-$I$	List-$II$
$A$. Nitrogen oxides in air	$I$. Eutrophication
$B$. Methane in air	$II$. $pH$ of rain water becomes $5.6$
$C$. Carbon dioxide	$III$. Global warming
$D$. Phosphate fertilisers in water	$IV$. Acid rain
