Consider these reactions, where M represents a generic metal.
1.
2M(s) + 6HCl(aq) ? 2MCI, (aq) + 3 H2(g)
??? = -887.0 kJ
2.
HCI(g) ? HCl(aq)
??? = -74.8 kJ
3.
H2(g) + Cl2(g) ? 2HCl(g)
??? = -1845.0 kJ
4.
MCl, (s) ? MCl, (aq)
??? = -415.0 kJ
Use the given reactions to determine the enthalpy of the following reaction.
2M(s) + 3Cl?(g) ? 2 MCI, (s)
Step 2: Identify how the enthalpies of the individual reactions are affected after the equations are manipulated.
