B. the vibrations produced by an earthquake 6.11 Which of the following pairs of elements are likely to form an ionic compound? The forces that hold Ca and O together in CaO are much stronger than those that hold Na and F together in NaF, so the heat of fusion of CaO is almost twice that of NaF (59 kJ/mol versus 33.4 kJ/mol), and the melting point of CaO is 2927C versus 996C for NaF. Very little energy is needed to remove electrons from a solid metal because they are not bound to a single nucleus. Based on their positions, predict whether each solid is ionic, molecular, covalent, or metallic. The enthalpies of fusion also increase smoothly within the series: benzene (9.95 kJ/mol) < naphthalene (19.1 kJ/mol) < anthracene (28.8 kJ/mol).

B2O3 Binary Molecular and Ionic Compound Formulas Expert Answer 100% (4 ratings) Answer: View the full answer Compounds that are composed of only non-metals or semi-metals with non-metals will display covalent bonding and will be classified as molecular compounds. The reactions are: H3BO3 HBO2 + H2O. If the molecules have shapes that cannot pack together efficiently in the crystal, however, then the melting points and the enthalpies of fusion tend to be unexpectedly low because the molecules are unable to arrange themselves to optimize intermolecular interactions. Compound Name Molecular or Ionic Compund? Thus toluene (C6H5CH3) and m-xylene [m-C6H4(CH3)2] have melting points of 95C and 48C, respectively, which are significantly lower than the melting point of the lighter but more symmetrical analog, benzene.
