Question

Name the metal which is stored under kerosene?

Answer 1

• Some metals are very reactive toward air or oxygen so they cannot be exposed to air.
• In order to store such metals that are more reactive toward the air, Kerosene is used.
• Sodium is a metal that vigorously reacts with air.
• So, Sodium is the metal that is stored in Kerosene to prevent its reaction with air for forming Sodium oxide $\left({\mathrm{Na}}_{2}O\right)$
• The chemical reaction occurs as follows:

$4\mathrm{Na}\left(s\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to \underset{(\mathrm{Sodium}\mathrm{oxide})}{2{\mathrm{Na}}_2\mathrm{O}\left(\mathrm{s}\right)}$
