![### Question 1
A calorimetry experiment determined that the combustion of 1.01 g of \( \text{H}_2(\text{g}) \) reacting with excess \( \text{O}_2(\text{g}) \) gave \( q_{\text{soln}} = 143 \, \text{kJ} \). Calculate \( \Delta H \) for the reaction:
\[ \text{H}_2(\text{g}) + \frac{1}{2} \text{O}_2(\text{g}) \rightarrow \text{H}_2\text{O (l)} \]
