- Based on the diagram above, which of the following best helps to explain why MgO(s) is not able to conduct electricity, but MgO(l) is a good conductor of electricity?
A.
MgO(s) does not contain free electrons, but MgO(l) contains free electrons that can flow.
B.
MgO(s) contains no water, but MgO(l) contains water that can conduct electricity.
C.
MgO(s) consists of separate Mg2+ ions and O2โ ions, but MgO(l) contains MgO molecules that can conduct electricity.
D.โ Correct
MgO(s) consists of separate Mg2+ ions and O2โ ions held in a fixed lattice, but in MgO(l) the ions are free to move and conduct electricity.
