B. `Cl_2`
C. `POCl_3`
D. Both (1) and (2)

Answer

To complete the reaction of PCl5 when heated, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactant**: The reactant in this reaction is phosphorus pentachloride (PCl5).

2. **Understand the Type of Reaction**: Since we are heating PCl5, we are looking at a decomposition reaction. A decomposition reaction occurs when a single compound breaks down into simpler products.

3. **Write the Decomposition Reaction**: When PCl5 is heated, it decomposes into phosphorus trichloride (PCl3) and chlorine gas (Cl2). The balanced equation for this reaction is:
\[ \text{PCl}_5 \xrightarrow{\text{Heat}} \text{PCl}_3 + \text{Cl}_2 \]

4. **Identify the Products**: From the decomposition reaction, we can see that the products formed are:
- Phosphorus trichloride (PCl3)
- Chlorine gas (Cl2)

5. **Conclusion**: Therefore, the products of the reaction when PCl5 is heated are PCl3 and Cl2.

### Final Answer:
The products are PCl3 and Cl2.
