Write a balanced chemical equation with state symbols for the following reactions :
Solutions of barium chloride and sodium sulphate in water react to give insoluble barium sulphate and the solution of sodium chloride.

Explanation

To write a balanced chemical equation for the reaction between barium chloride and sodium sulfate, we will follow these steps:

### Step 1: Write the formulas for the reactants and products.
- **Barium Chloride**: The formula is \( \text{BaCl}_2 \).
- **Sodium Sulfate**: The formula is \( \text{Na}_2\text{SO}_4 \).
- **Barium Sulfate** (the insoluble product): The formula is \( \text{BaSO}_4 \).
- **Sodium Chloride** (the other product): The formula is \( \text{NaCl} \).
