Part par? release? contumet conturned and intelsed equaly nether From the ionic radii given in the figure, calculate the potential energy of a single CaO ion pair that is just touching. e=1.601019C=8.99109Jm/C2 Express your answer in joules to three significant figures. Part D Calculate the energy of four moles of such CaO ion pairs. Express your answer in kilojoules to three significant figures. How does the potential energy compare to the lattice energy of CaO ? The potential energy of CaO is greater than the lattice energy. The lattice energy of CaO is greater than the potential energy. Potential energy is not comparable to lattice energy. The potential and lattice energies of CaO are equal. X Incorrect; Try Again; 5 attempts remaining Part F What factor do you think accounts for most of the discrepancy between the energies in part (d)-the bonding in CaO is mo covalent than ionic, or the electrostatic interactions in a crystal lattice are more complicated than those in a single ion pair The electrostatic interactions in a crystal lattice are less complicated than those in a single ion pair. The electrostatic interactions in a crystal lattice are more complicated than those in a single ion pair. The bonding in CaO is more covalent than ionic. The bonding in CaO is more ionic than covalent
