Answer

To determine the H-O-O bond angle in hydrogen peroxide (H₂O₂), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Molecular Structure**:
- Hydrogen peroxide (H₂O₂) consists of two hydrogen atoms and two oxygen atoms. The molecular structure can be represented as H-O-O-H.

2. **Draw the Lewis Structure**:
- The Lewis structure for H₂O₂ shows that each oxygen atom is bonded to one hydrogen atom and is also bonded to each other. This gives us a central O-O bond with two terminal H-O bonds.

3. **Determine the Bond Angles**:
- The bond angle we are interested in is the angle formed between the two hydrogen atoms through the central oxygen-oxygen bond.

4. **Use VSEPR Theory**:
- According to Valence Shell Electron Pair Repulsion (VSEPR) theory, the arrangement of electron pairs around the central atom will determine the bond angles. In H₂O₂, the two oxygen atoms are bonded to each other and to hydrogen atoms, creating a bent shape.

5. **Measure the H-O-O Bond Angle**:
- The H-O-O bond angle in hydrogen peroxide is approximately 94.8 degrees.

6. **Conclusion**:
- Therefore, the H-O-O bond angle in H₂O₂ (g) is 94.8 degrees.

### Final Answer:
The H-O-O bond angle in H₂O₂ (g) is 94.8 degrees.
