Consider these reactions, where M represents a generic metal.
1.
2 M(s) + 6 HC1(aq) -
2 MCL, (aq) + 3 Н, (в)
AH = -820.0 kJ
2.
HCl(g) HCI(aq)
AH2 = -74.8 kJ
3.
H, (g) + Cl, (g) –→ 2 HCI(g)
AH3 = -1845.0 kJ
4.
MCI, (8) → MC, (aq)
AH4 = -207.0 kJ
Use the given information to determine the enthalpy of the reaction
2 M(s) + 3 Cl, (g)
2 MCI,(s)
kJ
AH =
MacB
