2. Consider the following three reactions: 2 Fe (s) + 6 HCI (aq) 2 Fech (aq) + 3 H2 (9) H: Fe,0, (s) + 6 HCI (aq) 2 FeCl (aq) + 3 H20 (1) H2 2 H2 (9) + O2(g) - 2 H20 () H Show how these equations must be manipulated and summed together according to Hess's Law to determine AH for the combustion of iron (target equation shown below). Fe (s) + O2 (9) - Fe,O, (s) HE? 3. Express the enthalpy of combustion of iron in terms of the enthalpy of formation of iron(III)oxide.
