Write a balanced equation for the following chemical reactions. i) Hydrogen + Chloride —-> Hydrogen chloride ii) Barium chloride + Aluminium sulphate —> Barium sulphate + Aluminium chloride

A chemical equation represents a chemical process as a collection of substances. A balanced chemical equation has the same number of atoms on both sides of the equation.

(i) H₂ (g) + Cl₂ (g) → 2HCl (g)

Hydrogen gas combines with chlorine gas to form hydrogen chloride gas.

(ii) 3BaCl₂ (s) + Al₂(SO₄)₃ (s) → 3BaSO₄(s) + 2AlCl₃ (s)

When barium chloride reacts with aluminium sulphate to give barium sulfate and aluminium chloride.
