Answer

To solve the question regarding the reaction of barium azide (Ba(N₃)₂) decomposing into barium and nitrogen gas, we will analyze the reaction step by step.

### Step-by-Step Solution:

1. **Identify the Reaction Type**:
The given reaction is:
\[ \text{Ba(N}_3\text{)}_2 \xrightarrow{\Delta} \text{Ba} + \text{N}_2 \uparrow \]
Here, barium azide (Ba(N₃)₂) is decomposing into barium (Ba) and nitrogen gas (N₂).

2. **Understand Decomposition Reactions**:
A decomposition reaction involves breaking down a single compound into two or more simpler products. In this case, Ba(N₃)₂ is breaking down into Ba and N₂.

3. **Classify the Reaction**:
Since Ba(N₃)₂ is a single compound that is breaking down into two products (Ba and N₂), this is classified as a **decomposition reaction**.

4. **Determine if it is a Redox Reaction**:
In a redox reaction, there is a transfer of electrons, leading to changes in oxidation states. In this case:
- Barium (Ba) remains in the same oxidation state (0) after decomposition.
- Nitrogen in azide (N₃) has an oxidation state of -1, and in N₂, it has an oxidation state of 0. This indicates that nitrogen is being oxidized.

5. **Conclusion**:
Since the reaction involves the breakdown of a compound into simpler substances and involves changes in oxidation states, it is classified as a **decomposition redox reaction**.

### Final Answer:
The reaction Ba(N₃)₂ decomposing into Ba and N₂ is a **decomposition redox reaction**.
