Solution

$Carbon dioxide$
$Carbon dioxide$ is an important constituent present in the air. Air contains 0.003% of $Carbon dioxide$ .
$Carbon dioxide$ is consist of single $Carbon atom$ and two $Oxygen atom$ . So the chemical formulae of $Carbon dioxide$ is ${CO}_{2}$ .
$Carbon dioxide$ is obtained by burning $Carbon (C)$ .
Chemical equation : $\underset{Carbon}{C (s)} + \underset{Oxygen}{O_{2} (g)} \overset{∆}{\to} \underset{Carbon dioxide}{{CO}_{2} (g)}$
Uses of $Carbon dioxide$
$Carbon dioxide ({CO}_{2})$ is used for the preparation of chemical $Sodium bicarbonate ({NaHCO}_{3})$ .
It is dissolved in water under pressure to produce plain soda. If it is dissolved in a sugar solution containing different flavours then it forms soft drinks.
$Carbon dioxide ({CO}_{2})$ is neither burns nor supports combustion so it is used as a fire extinguisher.
Solid form of $Carbon dioxide ({CO}_{2})$ is known as dry ice which is used to preserve food, meat, and ice creams
