The lattice energy of Mgl2is -2327 kJ/mol. This energy corresponds to which reaction below?
Mg(s) + 12 (g) - Mg 2 (s)
Mg2+ (g) + 21- (g) - Mg 2 (s)
Mg2+ (aq) + 21- (aq) → Mg12 (s)
Mg (g) + 21 (g) - Mg 2 (s)
Mg (g) + 21 (g) - Mg12 (g)

Count the number of each type of atom in the equation below, and then balance the equation. write in the numbers of atoms and coefficients. add a 1 if there should be no coefficient. cs2(l) + o2(g) → co2(g) + so2(g) c [ ] s [ ] o > c [ ] s [ ] o [ ] cs2(l) + [ ] o2(g) > [ ] co2(g) + [ ] so2(g)
