The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Decomposition Reaction**: - Hydrogen peroxide (H₂O₂) decomposes into water (H₂O) and oxygen (O₂) when exposed to light. The chemical equation for this reaction can be represented as: \[ 2 H_2O_2 \rightarrow 2 H_2O + O_2 \] 2. **Effect of Light on Decomposition**: - The presence of light acts as a catalyst for the decomposition of hydrogen peroxide. It accelerates the breakdown of H₂O₂ into its constituent products. 3. **Storage of Hydrogen Peroxide**: - Due to its sensitivity to light, hydrogen peroxide is typically stored in dark or opaque containers to minimize exposure to light, which helps in preventing its decomposition. - Additionally, bottles lined with wax or made of dark materials are often used to protect H₂O₂ from light. 4. **Conclusion**: - In summary, hydrogen peroxide decomposes slowly when exposed to light, leading to the formation of water and oxygen. Proper storage methods are essential to maintain its stability.
