The empirical formula for the unknown compound would be: C2H4O (2 molecules of Carbon, 4 molecules of Hydrogen, and 1 molecule of Oxygen)
Greg is correct, Jill is wrong. Only heat can be released.
1) ionic compound
there should be motive ions or free movable electrons to conduct electricity. The ionic compounds in the solid state, has no motive ions or free electrons as the ions are tightly attracted to each other. But in liquid state, the ions separate and move freely.
