Question

Write the balanced equation for the following chemical reactions.
(i) Hydrogen + Chlorine `rarr` Hydrogen chloride
(ii) Barium chloride + Aluminium sulphate `rarr` Barium sulphate + Aluminium chloride
(iii) Sodium + Water `rarr` Sodium hydroxide + Hydrogen

Answer 1

The balanced equations are written for the symbol equations and not for word equations.
(i) `H_(2) + Cl_(2) to 2HCl`
(ii) `2Na + 2H_(2)O to 2NaOH + H_(2)`
(iii) `3BaCl_(2) + Al_(2)(SO_(4))_(3) to 3BaSO_(4) + 2AlCl_(3)`
