A:

Metals react with water to form metal hydroxide along with the evolution of hydrogen gas.

Metal   + Water  →   Metal hydroxide  + Hydrogen

Example: Sodium reacts violently with cold water to form sodium hydroxide solution along with the evolution of hydrogen gas.

2Na     +  2H2O  →  2NaOH  + H2
