Refer to Example 12-12. Together with data given there, use the data here to calculate Δ_fH° for 1 mol MgCl₂(s). Explain why you would expect MgCl₂ to be a much more stable compound than MgCl. (The second ionization energy of Mg is 1451 kJ mol^-1; the lattice energy of MgCl₂(s) is -2526 kJ mol^-1 MgCl₂.)

Example 12-12

With the following data, calculate Δ_fH° of MgCl(s): Enthalpy of sublimation of Mg(s): +146 kJ mol^-1; enthalpy of dissociation of Cl₂(g): +244 kJ mol^-1; first ionization energy of Mg(g): +738 kJ mol^-1; electron affinity of Cl(g): -349 kJ mol^-1; lattice energy of MgCl(s): -676 kJ mol^-1.
