A) \[N{{O}_{2}}\]and \[S{{O}_{2}}\]
B) \[N{{H}_{3}}\] and \[S{{O}_{2}}\]
C) \[CO\] and \[C{{O}_{2}}\]
D) \[{{O}_{3}}\]and \[C{{O}_{2}}\]
Correct Answer: A
Solution :
Acid rain is caused by large scale emission of nitrogen oxides (\[N{{O}_{\times }}\]) and \[S{{O}_{2}}\]. Volatile organic carbons and HCl from thermal power plants, industries and automobiles. \[\begin{align} & 2S{{O}_{2}}+{{O}_{2}}\to 2S{{O}_{3}} \\ & S{{O}_{3}}+{{H}_{2}}O\to {{H}_{2}}S{{O}_{4}} \\ & 2NO+O\to {{N}_{2}}{{O}_{5}} \\ & {{N}_{2}}{{O}_{5}}+{{H}_{2}}O\to 2HN{{O}_{3}} \\ \end{align}\]
