answers to #8 and #9
1 pts D Question 8 Why isn't lattice energy measured for covalent compounds? Covalent compounds form a lattice that is different than ionic compounds and thus another measure is used. Covalent compounds don't form the lattice structure that ionic compounds do. Covalent compounds do not satisfy the octet rule and thus do not have lattice energies. OCovalent compounds have high lattice energies and cannot be measured. Question 9 1 pts Which of the following ionic...
