What is the lattice energy of magnesium sulfide?

Mg(s) → Mg(g)

ΔH°rxn = 148 kJ/mol

   Mg(g) → Mg22+(g) + 2e

ΔH°rxn = 2186 kJ/mol

   S8(s) → 8S(g)

ΔH°rxn = 2232 kJ/mol

   S(g) + 2e→ S22(g)

ΔH°rxn = 450. kJ/mol

   8Mg(s) + S8(s) → 8MgS(s)

ΔH°rxn = 2744 kJ/mol

   MgS(s) → Mg22+(g) + S22(g)

ΔH°rxn= ?



▸ –3406 kJ/mol

▸ –2720. kJ/mol

▸ –2272 kJ/mol

▸ 2720. kJ/mol

▸ 3406 kJ/mol
