2. Consider the following three reactions: 2 Fe (s) + 6HCl (aq) → 2 FeCl3 (aq) + 3 H2 (g) ΔHA Fe2O3 (s) + 6HCl (aq) → 2 FeCl3 (aq) + 3 H2O (l) ΔHB 2H2 (g) + O2 (g) → 2 H2O (l) ΔHC a. Show how these equations must be summed together according to Hess’s Law to determine ∆H for the combustion of iron (target equation shown below). Also show clearly how the ∆H 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) ∆H = ?
