Consider these reactions, where M represents a generic metal
1. 2M(s) + 6HCl(aq) → 2MCl3(aq) + 3H2(g) ΔH1 = -749.0 KJ
2. HCl(g) → HCl(aq) ΔH2 = -74.8 KJ
3. H2(g)+Cl2(g) → 2HCl(g) ΔH3 = -1845.0 KJ
4. MCl3(s) → MCl3(aq) ΔH4 = -298.0 KJ
Use the information above to determine the enthalpy of the following reaction.
2M(s) + 3Cl2(g) → 2MCl3(s) ΔH =
