Answer 2

Answer:

A)The reason behind storing the potassium and sodium in kerosene is because they are highly reactive in air and could burn any time. They are preserved in kerosene or dry mineral oil. These metals are stored in kerosene to protect this element from moisture or water content.

B)Plastic containers are favoured for storing food because plastic is non-reactive and will not react with the ingredients of the food items. Plastic is more easily accessible and is economically friendly to all people. Plastic containers are heavily used in the packaging industry.
