Write the balanced equations for the following chemical reactions.
1. Barium chloride + Sodium sulphate → Barium sulphate + Sodium chloride.
2. Sodium + Water → Sodium hydroxide + Hydrogen
The balanced chemical equations for the said reactions are as follows :
1) BaCl2 + Na2SO4 → BaSO4 + 2NaCl
2) 2Na + 2H2O → 2NaOH + H2
