9) Solid MgO Liquid MgO Based on the diagram above, which of the following best helps to explain why MgO(s) is not able to conduct electricity, but MgO(1) is a good conductor? O MgO(s) consists of separate Mg2* and O2 ions held in a fixed lattice, but in MgO() the ions are free to move, and can therefore conduct electricity. MgO(s) contains molecules, but MgO(1) consists of a fixed lattice of Mg2+ and O2- ions that can conduct electricity. MgO(s) does not contain free electrons, but MgO(1) contains free electrons that can flow. MgO(s) consists of separate Mg2* and O2 ions, but MgO(1) contains molecules that can conduct electricity. MgO(s) does not contain water, but MgO(0) contains water that can conduct electricity.
Prior to manufacturing, you realize that Er and Y could form a pass ovation later on the surface of the alloy upon oxidation with Oxygen, with the oxides Er2O3 and Y2O3. There is a concern that the layers might be too hard (brittle) for practical purposes. You remember ionic compounds are harder and more brittle than a covalent compound, and decide to quantify the percent ionic character of the bonding. Find the % ionic character of the interatomic bonds for Er2O3 and Y2O3. (Electronegativity for Er is 1.2)
