GENERAL KNOWLEDGE

Detailed explanation-1: -Sodium is stored in kerosene because sodium reacts vigourously with oxygen and moisture due to its high reactivity so keeping it in kerosene will prevent sodium from coming in contact with oxygen and moisture.

Detailed explanation-2: -> Sodium is kept in kerosene because it is a highly reactive metal. If it is kept in an open container, it will react with oxygen and water vapor present in the atmosphere producing sodium oxides and sodium hydroxides respectively which is a highly exothermic reaction.

Detailed explanation-3: -Sodium is kept in Kerosene as: Sodium metal is a very reactive metal and its interactions with water are extremely exothermic. It reacts vigorously with oxygen and water. It can react with water vapor and oxygen present in the air and can produce a lot of heat.

Detailed explanation-4: -Sodium is a very reactive metal. It is kept in kerosene to prevent it from coming in contact with oxygen and moisture. If this happens, it will react with the moisture present in air and form sodium hydroxide (NaOH). This is a strongly exothermic reaction, and lot of heat is generated.

Detailed explanation-5: -Sodium and potassium are stored in kerosene because they are highly reactive elements. They can easily catch fire even when in contact with air.
