Write the balanced equation for the following chemical reactions.
(i) Hydrogen + Chlorine → Hydrogen chloride
(ii) Barium chloride + Aluminium sulphate → Barium sulphate +Aluminium chloride
(iii) Sodium + Water → Sodium hydroxide + Hydrogen
(i) H2 + Cl2 → HCl
H2 + Cl2 → 2HCl
(ii) BaCl2 + Al2(SO4)3 → BaSO4 + AlCl3
3BaCl2 + (Al2 SO4)3 →3BaSO4 + 2AlCl3
(iii) Na + H2O → NaOH + H2
2Na + 2H2O → 2NaOH + H2
