Plz answer according to 5marks question. ​

Answer 1

The metal is sodium.The chemical equation of when it is exposed in air is sodium hydroxile film. in water it is sodium hydroxide and hydrogen.

Answer 2

the metal e is here sodium.

the equestion is given below

2Na+2H2O->2NaOH+H2

The sodium metal has such chamical property that if it comes under the presence of water partical or humidity then it catches fire because according to reactivity series sodium is high reactive metal.
