#12.  Bond enthalpy is the energy to break 1 mole of a bond in the gas phase.  In addition, the energy is measure for breaking to gaseous atom not ions.

#18.  Solid zinc chloride has the ionic bonding such as solid sodium chloride. Zinc chloride does not conduct electricity as a solid becuse these ions are not free to move around.
