Write a balanced chemical equation for each of the following types of chemical reactions: Double displacement reaction

Explanation

To write a balanced chemical equation for a double displacement reaction, we will follow these steps:

### Step 1: Identify the Reactants
In a double displacement reaction, two compounds react and exchange ions. For this example, we will use the reaction between barium chloride (BaCl₂) and sodium sulfate (Na₂SO₄).

### Step 2: Write the Unbalanced Equation
The unbalanced equation for the reaction between barium chloride and sodium sulfate can be written as:
\[ \text{BaCl}_2 + \text{Na}_2\text{SO}_4 \rightarrow \text{BaSO}_4 + \text{NaCl} \]
