B) NaCl has a higher melting point because it is a solid at room temperature.
C) The aluminum oxide has a higher melting point because of the greater charges of the ions, and hence the greater force of attractions between them.
D) The aluminum oxide has a higher melting point because of the covalent bonds within the molecule.
