A metal occurs in nature as its ore X which is heating in air convert to Y.Y reacts with unreacted X to give the metal.The metal is

Hydrogen reacts with metal oxides to give the corresponding metals.

Alkali metal hydrides react with water to give

Give reasons : A sulphide ore is converted to its oxide to extract the metal.

A metal X reacts with water to produce a highly combustible gas Y, and a solution Z. another metal P reacts with Z to give the same gas Y. X,Y,Z and P respectively are
