Question
**Estimating the O—H Bond Energy in Water**

Use the following standard enthalpies of formation to estimate the O—H bond energy in water:

- **O\(_2\)(g)**: +249.0 kJ/mol
- **H\(_2\)(g)**: +216.0 kJ/mol
- **H\(_2\)O(g)**: -242.0 kJ/mol

**Calculate the Bond Energy:**

\[ \text{Bond energy} = \, \_\_\_\_ \, \text{kJ/mol} \]
