Consider these reactions, where M represents a generic metal.

1. 2M(s)+6HCl(aq)?2MCl  3 (aq)+3H  2 (g)ΔH 1 =−718.0 kJ 
2. HCl(g)?HCl(aq)  ΔH 2 =−74.8 kJ 
3. H  2 (g)+Cl  2 (g)?2HCl(g) ΔH 3 =−1845.0 kJ 
4. MCl  3 (s)?MCl  3 (aq)  ΔH 4 =−198.0 kJ 

Use the given information to determine the enthalpy of the reaction

2M(s)+3Cl  2 (g)?2MCl  3 (s) 

ΔH= ____kJ
