Question

Acid rain is produced by

• A. Excessive release of CO in air
• B. Excessive release of $SO_{2}$and $H_{2}S$in air
• C. Excessive release of $NO_{2}$and $SO_{2}$in air
• D. Excessive release of$NH_{3}$and $CO_{2}$in air.

Answer 1

Answer: (C)

Excessive release of $NO_{2}$and $SO_{2}$in air

Answer 2

: Acid rain is produced by excess of $NO_{2}$and $SO_{2}$ released from burning of fossil fuels.

$2 \mathrm { SO } _ { 2 } + \mathrm { O } _ { 2 } \rightarrow 2 \mathrm { SO } _ { 3 }$

$\mathrm { SO } _ { 3 } + \mathrm { H } _ { 2 } \mathrm { O }$ $\rightarrow H_{2}SO_{4}$

$4NO_{2} + O_{2} + 2H_{2}O \rightarrow 4HNO_{3}$
