One of the following pictures(Figure 1) represents NaCl and one represents MgO.
Which is which?
(a) is NaCl and (b) is MgO
(b) is NaCl and (a) is MgO
Which has the larger lattice energy?
NaCl
MgO
The lattice energy of CaO(s) is -3,460 kilojoules per mole; the lattice energy for K2O is -2,240 kilojoules per mole. Account for this difference.
The lattice energy of NaCl is 769 kJ/mole. Which of
the following is a correct statement about NaCl?
When one mole each of gaseous Nat and CI- ions form
solid NaCl, 769 kJ of heat is consumed.
It requires 769 kJ to separate one mole of solid NaCl into
one mole of each gaseous Na* and CI- ions.
It requires 769 kJ to separate one mole of solid NaCl into
gaseous one mole of Na* and two moles of CI- ions.
