Expert Answer
Kerosene is one of the fractions of crude oil composed of C12H26-C15H32.
Sodium reacts violently with cold water to form sodium hydroxide solution along with the evolution of hydrogen gas.
2Na + 2H2O → 2NaOH + H2 ↑
Since sodium reacts vigorously with the oxygen and water producing a lot of heat, it is stored in kerosene.
