Hydrogen peroxide cannot be stored in a simple glass bottle.

Answer

### Step-by-Step Solution:

1. **Understanding Hydrogen Peroxide (H₂O₂)**:
- Hydrogen peroxide is a chemical compound that can decompose into water (H₂O) and oxygen (O₂) under certain conditions.

2. **Decomposition Reaction**:
- The decomposition of hydrogen peroxide can be represented by the following chemical equation:
\[ 2 H₂O₂ \rightarrow 2 H₂O + O₂ \]
- This reaction shows that two molecules of hydrogen peroxide decompose to form two molecules of water and one molecule of oxygen gas.

3. **Effect of Sunlight**:
- Sunlight can act as a catalyst for the decomposition of hydrogen peroxide. When exposed to light, especially ultraviolet (UV) light, the stability of hydrogen peroxide is compromised, leading to its breakdown.

4. **Storage Conditions**:
- To prevent the decomposition of hydrogen peroxide, it should not be stored in simple glass bottles. Instead, it is recommended to use:
- **Wax-lined bottles**: These provide a barrier to light and help in preventing the decomposition reaction.
- **Plastic vessels**: These are also effective as they do not allow light to penetrate as easily as glass.

5. **Conclusion**:
- In summary, hydrogen peroxide cannot be stored in simple glass bottles due to the risk of decomposition caused by sunlight. It should be stored in wax-lined or plastic containers to maintain its stability.
