Answer

To solve the question regarding the reaction between Sodium Bromide (NaBr) and Silver Nitrate (AgNO₃), we will analyze the reaction step by step.

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactants in the reaction are Sodium Bromide (NaBr) and Silver Nitrate (AgNO₃).

2. **Write the Chemical Equation**:
- The reaction can be written as:
\[ \text{NaBr} + \text{AgNO}_3 \rightarrow \text{AgBr} + \text{NaNO}_3 \]

3. **Identify the Products**:
- The products of the reaction are Silver Bromide (AgBr) and Sodium Nitrate (NaNO₃).
- Silver Bromide (AgBr) is known to form a yellow precipitate.

4. **Determine the Type of Reaction**:
- This reaction involves the formation of a precipitate (AgBr) from the reactants.
- Since a solid (precipitate) is formed from two aqueous solutions, this is classified as a **precipitation reaction**.

5. **Conclusion**:
- The correct classification of the reaction is a **precipitate formation reaction**.

### Final Reaction:
\[ \text{NaBr} + \text{AgNO}_3 \rightarrow \text{AgBr (s)} + \text{NaNO}_3 \]
