Question

Give Reason- A) Sodium is Stored in Kerosene oil. B) Diamond is used for making

jewellery.​

Answer 1

Answer:

A.Sodium is a highly reactive metal and reacts vigorously with the oxygen, carbon dioxide and moisture present in the air such that it may even cause a fire. To prevent this explosive reaction, Sodium is kept immersed in kerosene because Sodium doesn't react with kerosene.

B.Diamond is used in jewellery because, when cut by experts, it will sparkle and reflect light in an attractive way. Diamond's hardness and high melting point make it useful for cutting tools, such as the diamond-tipped discs used to cut bricks and concrete.
