Here's the solution to your question:
a)
(i) Hess's Law states that the total enthalpy change for a chemical reaction is independent of the pathway taken, as long as the initial and final conditions are the same.
(ii) We are given the following reactions and their enthalpy changes:
1. $\text{C}_2\text{H}_5\text{OH}(\text{l}) + 3\text{O}_2(\text{g}) \to 2\text{CO}_2(\text{g}) + 3\text{H}_2\text{O}(\text{l})$ $\Delta H_1 = -1370 \text{ kJ/mol}$
2. $\text{C}_
