### Chemical Reaction: Double Displacement

This balanced chemical equation illustrates a double displacement reaction between sodium carbonate and barium chloride in aqueous solutions:

**Equation:**

\[ \text{Na}_2\text{CO}_3 \, (\text{aq}) + \text{BaCl}_2 \, (\text{aq}) \rightarrow 2\text{NaCl} \, (\text{aq}) + \text{BaCO}_3 \, (\text{s}) \]

**Explanation:**

- **Reactants:**
  - **Sodium Carbonate (\( \text{Na}_2\text{CO}_3 \)):** A soluble ionic compound.
  - **Barium Chloride (\( \text{BaCl}_2 \)):** Another soluble ionic compound.

- **Products:**
  - **Sodium Chloride (\( \text{NaCl} \)):** A soluble compound that remains in aqueous solution.
  - **Barium Carbonate (\( \text{BaCO}_3 \)):** An insoluble compound that precipitates as a solid.

**Key Points:**

- The reaction involves the exchange of ions between the reactants, leading to the formation of new products.
- **Barium Carbonate** forms a precipitate, a solid that settles out of the solution, indicating the occurrence of the reaction.
- This type of reaction is commonly used in chemistry to identify the presence of certain ions in a solution.
