The correct formula for lead IV oxide is PbO2.
Lead IV oxide, also known as plumbic oxide, contains lead in its +4 oxidation state. In this compound, each lead (Pb) atom is bonded to two oxide (O) ions. Therefore, the ratio of lead to oxygen is 1:2, resulting in the formula PbO2.
To clarify, options A (Pb2O4) and B (Pb4O2) imply different stoichiometry that does not represent the correct oxidation states of lead in this compound. Option C (PbO) corresponds to lead II oxide, while option E (Pb2O) might suggest a different oxidation state that doesn’t correspond to lead IV oxide. Thus, the correct choice for lead IV oxide is indeed PbO2.
