A chemist measures the enthalpy change \( \Delta H \) during the following reaction: \[ 2 \mathrm{H}_{2} \mathrm{O}(I)+\mathrm{O}_{2}(g) \rightarrow 2 \mathrm{H}_{2} \mathrm{O}_{2}(\text { I } \quad \quad \Delta H=196 . \mathrm{kJ} \] Use this information to complete the table below. Round each of your answers to the nearest \( \mathrm{kJ} / \mathrm{mol} \).
