Answer 1

hey frnd here is your answer!!!

a. Sodium is high reactive element. If it is kept in open it can explosively react with oxygen to catch fire. Hence to prevent accidental damage sodium is immersed in kerosene oil.

b. Because it is highly reactive, and spontaneously combusts when exposed to the air.

c. Since water contains protons as H+ . Therefore sodium will lose one electron to the proton. And in this process a lot of energy is released. Therefore to cut the supply of moisture from air or any other source sodium is kept in kerosene.
