Bleaching powder and hydrogen peroxide react to give _____.

Explanation

To solve the question about the reaction between bleaching powder and hydrogen peroxide, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components**:
- Bleaching powder is primarily composed of calcium hypochlorite (Ca(OCl)₂) and calcium chloride (CaCl₂).
- Hydrogen peroxide is represented as H₂O₂.

2. **Understand the Reaction**:
- The relevant part of bleaching powder that reacts with hydrogen peroxide is calcium hypochlorite (Ca(OCl)₂).
- In this reaction, hydrogen peroxide acts as a reducing agent.

3. **Write the Reaction**:
- The chemical reaction can be represented as:
\[ \text{Ca(OCl)₂} + \text{H₂O₂} \rightarrow \text{CaCl₂} + \text{H₂O} + \text{O₂} \]

4. **Identify the Products**:
- From the reaction, we can see that the products formed are:
- Calcium chloride (CaCl₂)
- Water (H₂O)
- Oxygen gas (O₂)

5. **Conclusion**:
- Therefore, the reaction between bleaching powder and hydrogen peroxide yields calcium chloride, water, and oxygen.

### Final Answer:
Bleaching powder and hydrogen peroxide react to give calcium chloride, water, and oxygen.
