2 Fe(s) + 6 HCl(aq) →2 FeCl3(aq) + 3 H2(g) ΔHa Fe2O3(s) + 6 HCl(aq) → 2 FeCI3(aq) + 3 H2O(l) ΔHb 2 H2(g) + O2(g) → 2 H2O(l) ΔHc Show how these equations must be summed together according to Hess's Law to determine ΔH for the combustion of iron (target equation shown below). Also show clearly how the ΔH values of each of the three reactions must be manipulated to determine the enthalpy of combustion of iron. 4 Fe(s) + 3 O2(g) → 2 Fe2O3(s) ΔH = ?
