Problem

When 0.0222 mol of decane,

\text{C}_{10}\text{H}_{22}

, is combusted in an excess of oxygen, the heat energy change of the surroundings is 145 kJ. Use this information to calculate the enthalpy change of the reaction given below:

2 \text{C}_{10}\text{H}_{22}(\text{l}) + 31 \text{O}_2(\text{g}) \rightarrow 20 \text{CO}_2(\text{g}) + 22 \text{H}_2\text{O}(\text{l}) \quad \Delta H^\ominus = ?
