Answer 1

Answer:

sodium is highly reactive therefore it immediately reacts and disappears as soon as it is exposed to air .It also reacts vigorously with water .For this reason sodium is stored in kerosene .White phosphorus readily catches fire at room temperature but it does not react with water .Hence it is stored in water.

A= calcium

Formula of A=CaO

Formula of the compound used for white washing =Ca(OH)²

Common names and uses of A = Calcium found in bones and teeth ,found in the earths crust, chalk and cement ;Common names of Calcium ÷ quicklime , used in white washing .

Common names of hydroxide of Calcium = Slaked lime , used in white washing.
