Question:

Why is sodium kept immersed in kerosene oil?

Answer:

Sodium is highly reactive metal so it  combines with air as well as water to form sodium oxide and hydrogen gas with heat energy.this heat is sufficient to burn hydrogen gas. That's why it catches fire if kept in open. Therefore, to prevent  sodium from combining with air and accidental fires, sodium is stored in kerosene oil.
