Homework Help: Chemistry

Posted by Garcia on Thursday, November 29, 2012 at 1:05pm.

Consider an ionic compound, MX2, composed of generic metal M and generic halogen X.

The enthalphy of formation of MX2= -891.
The enthalphy of sublimation of M= 141.
The first and second ionization energies of M are 605 and 1392.
The electron affinity of X= -339.
The bond energy of X2= 177.

I used the Born-Haber cycle and came up with:
-Lattice energy of MX2=-891-(141+88.5+605-678) to come up with the answer that the -lattice energy of MX2 is -1047.5 but i'm getting marked wrong. Where did I go wrong?????
