Answer #1

                        lattice energy

MgO                3890KJ/mole     MgO contains Mg+2 di positive and O2- di negative ion.

MgF2              2962KJ/mole   only contion has dipositive

NaF                 904KJ/mole   Bothe are uni positive

KCl                   699Kj/mole both are unipositive

MgO> MgF2>NaF>Kcl

In an ionic compound, the size of the ions affects the internuclear distance (the distance between the centers of adjacent ions), which affects lattice energy (a measure of the force need to pull ions apart), which affects the enthalpy of solution. Based on ion sizes, rank these compounds by their expected heats of solution. Most exothermic to most endothermic. Substances are Kf Kl KBr KCl
