Answer:

Sodium is highly reactive. When kept in air, it catches fire.

When in water it burns producing bright flames.

This is why it is kept in kerosene as it is not reactive to kerosene.

Explanation:

Answer 2

Answer:

reasons of storing sodium in kerosene oil:-

sodium belongs to the first group elements of periodic table which are highly reactive so sodium can react with moisture and form hydrogen gas which produces flame and can burn easily at normal temperature. so sodium is put under the kerosene oil which prevent it to react with moisture and cannot burn.

the reaction of sodium and moisture present in atmosphere is:-

$2Na + 2H_2O \: \implies \: 2NaOH \: + H_2$

hydrogen burns and produce flame which can cause harm due to which sodium is kept in kerosene which is out of range of moisture.
