Write the balanced equations for the following chemical reactions.
Barium chloride + aluminium sulphate `to` barium sulphate + aluminium chloride

Explanation

To write the balanced equation for the reaction between barium chloride and aluminium sulphate to form barium sulphate and aluminium chloride, we will follow these steps:

### Step 1: Write the unbalanced equation
We start by writing the chemical formulas for the reactants and products. The reactants are barium chloride and aluminium sulphate, and the products are barium sulphate and aluminium chloride.

**Unbalanced equation:**
\[ \text{BaCl}_2 + \text{Al}_2(\text{SO}_4)_3 \rightarrow \text{BaSO}_4 + \text{AlCl}_3 \]
