Question

Sublimation energy of Ca is 121 kJ/mol. Dissociation energy of $Cl_2$ is 242.8 kJ/mol, the total ionization energy of Ca(g) -> Ca2+(g) is 2422 kJ/mol and electron affinity of Cl is -355 kJ/mol. Lattice energy of $CaCl_2$ is -2430.8 kJ/mol. What is δ H for the process Ca(s) + $Cl_2$(g) -> $CaCl_2$(s)?
