Consider these reactions, where M represents a generic metal. 1. 2 M(s) + 6 HCl(aq) 2 MC1z (aq) + 3H2(g) AH = -792.0 kJ = 2. HCl(g) HCl(aq) AH2 = -74.8 kJ = 3. H2(g) + Cl2(g) 2 HCl(g) AH3 = -1845.0 kJ = 4. MCI,(s) MCI, (aq) 4 = -470.0 kJ Use the given information to determine the enthalpy of the reaction 2 M(s) + 3 Cl, (g) 2 MCI,(s) -1574.6 AH = Incorrect
