Consider these reactions, where $\mathrm{M}$ represents a generic metal. 1. $2\mathrm{M}(\mathrm{s})+6\mathrm{HCl}(\mathrm{aq})⟶2{\mathrm{MCl}}_3(\mathrm{aq})+3{\mathrm{H}}_2(\mathrm{g})$ $\Delta H_1=-895.0\mathrm{kJ}$ 2. $\mathrm{HCl}(\mathrm{g})⟶\mathrm{HCl}(\mathrm{aq})$ $\Delta H_2=-74.8\mathrm{kJ}$ 3. ${\mathrm{H}}_2(\mathrm{g})+{\mathrm{Cl}}_2(\mathrm{g})⟶2\mathrm{HCl}(\mathrm{g})$ $\Delta H_3=-1845.0\mathrm{kJ}$ 4. ${\mathrm{MCl}}_3(\mathrm{s})⟶{\mathrm{MCl}}_3(\mathrm{aq})$ $\Delta H_4=-297.0\mathrm{kJ}$ Use the given reactions to determine the enthalpy of the following reaction. $2\mathrm{M}(\mathrm{s})+3{\mathrm{Cl}}_2(\mathrm{g})\to 2{\mathrm{MCl}}_3(\mathrm{s})$ Step 3: Determine the enthalpy of the overall reaction from the adjusted enthalpies of the individual reactions.
