Question

Consider these reactions, where M represents a generic metal. 

1.     2M(s) + 6HCl(aq) yields to 2MCl3(aq) + 3H2(g)    Detal H1=-571.0 kJ

2.     HCl(g) yields to HCl(aq)                                            Delta H2=-74.8 kJ 

3.     H2(g) + Cl2(g) yields to 2HCl(g)                            Delta H3=-1845.0 kJ

4.     MCl3(s) yields to MCl3(aq)                                       Delta H4=-370.0 kJ 

Use the given information to determine the enthalpy of the reaction 

2M(s) + 3Cl2(g) yields to 2MCl3(s)

Use the correct number of significant digits.
