Hydrogen combines with oxygen to form water. $\text{H} - \text{H} + \text{O} = \text{O} \rightarrow \text{H} - \text{O} - \text{H}$ A table shows some bond energies. Use the data in the table to determine the enthalpy change of reaction.
- A$-920\ \text{kJ mol}^{-1}$
- B$-834\ \text{kJ mol}^{-1}$
- C$-484\ \text{kJ mol}^{-1}$
- D$+442\ \text{kJ mol}^{-1}$
