Burning of fossil fuels produce ${\mathrm{SO}}_2$ and NOx .

They are major contributors to acid rain on ${\mathrm{r}}_{\mathrm{xn}}$ with water.

$$\begin{array}{c}2{\mathrm{SO}}_2(\mathrm{g})+{\mathrm{O}}_2(\mathrm{g})+2{\mathrm{H}}_2\mathrm{O}(\ell )\to 2{\mathrm{H}}_2{\mathrm{SO}}_4(\mathrm{aq})\end{array}$$

$$4{\mathrm{NO}}_2(\mathrm{g})+{\mathrm{O}}_2(\mathrm{g})+2{\mathrm{H}}_2{\mathrm{O}}_{(\ell )}\to 4{\mathrm{HNO}}_3(\mathrm{aq})$$

$Also,{\mathrm{H}}_2{\mathrm{O}}_{(\ell )}+{\mathrm{CO}}_2(\mathrm{g})\rightleftharpoons {\mathrm{H}}_2{\mathrm{CO}}_3(\mathrm{aq})$
