Question

Burning of fossils fuels causes air pollution because they release on combustion.

• A. $C{O}_2$
• B. $C{H}_4$
• C. $C_2{H}_6$

Answer 1

The correct option is A $C{O}_2$

Fossil fuels are obtained from the fossils of dead vegetation and animals over millions of years, under high temperature and pressure. They contain carbon in them, which undergoes combustion on burning, in the presence of oxygen to produce carbon dioxide $\left(C{O}_2\right)$. If the oxygen supply is less, carbon monoxide $\left(CO\right)$ is produced instead of $C{O}_2$.
$C\left(s\right)+O_2\left(g\right)\underset{}{\overset{\Delta }{\to }}{\mathrm{CO}}_2\left(g\right)$
$C{O}_2$ gas causes global warming. Carbon monoxide is a poisonous gas, which when inhaled for longer periods can even cause death.
