Calculate the lattice energy for MgO(s) using a Born-Haber cycle and the following information:

   MgO(s) → Mg2+(g) + O2-(g)   ?
   Mg(s) → Mg(g)   +147.1 kJ/mol
   Mg(g) → Mg+(g) + e-   +737.8 kJ/mol
   Mg+(g) → Mg2+(g) + e-   +1451 kJ/mol
   1/2 O2(g) → O(g)   +249.0 kJ/mol
   O(g) + e- → O-(g)   -141.1 kJ/mol
   O-(g) + e- → O2-(g)   +798.0 kJ/mol
   Mg(s) + 1/2 O2(g) → MgO(s)   -601.8 kJ/mol

A) +1842 kJ/mol
B) +2444 kJ/mol
C) +3844 kJ/mol
D) +4108 kJ/mol
