Answer

To solve the question regarding the reaction between barium nitrate and sodium sulfate, we can break it down into a step-by-step analysis.

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactants in the given reaction are Barium Nitrate, \( \text{Ba(NO}_3\text{)}_2 \), and Sodium Sulfate, \( \text{Na}_2\text{SO}_4 \).

2. **Write the Chemical Equation**:
- The balanced chemical equation for the reaction is:
\[ \text{Ba(NO}_3\text{)}_2 + \text{Na}_2\text{SO}_4 \rightarrow \text{BaSO}_4 + 2\text{NaNO}_3 \]

3. **Identify the Products**:
- The products formed from this reaction are Barium Sulfate, \( \text{BaSO}_4 \), and Sodium Nitrate, \( \text{NaNO}_3 \).

4. **Determine the Type of Reaction**:
- In this reaction, Barium Sulfate is formed as a solid precipitate. A precipitate is an insoluble solid that emerges from a liquid solution during a chemical reaction.

5. **Classify the Reaction**:
- Since a solid precipitate (Barium Sulfate) is formed from the reaction of two soluble salts (Barium Nitrate and Sodium Sulfate), this reaction is classified as a **Precipitate Formation Reaction**.

6. **Conclusion**:
- The correct classification for the reaction \( \text{Ba(NO}_3\text{)}_2 + \text{Na}_2\text{SO}_4 \rightarrow \text{BaSO}_4 + 2\text{NaNO}_3 \) is a **Precipitate Formation Reaction**.
