Webb, PbO2 is +4 and -4 (multiply O by 2), but on the product side, PbSO4 is +2 and -2. Is the reason that we don't multiply O on the product side by 4 is that SO4 -2 is an ion and so it stays -2, (I guess 2- because it is an oxidation state we're talking about, not a charge). So to do Redox reactions, I really need to know my ions, don't I? • WebbCalculate the percent by mass of the element listed first in the formula for tin (IV) oxide, SnO2. The mass (g) of Cu is 0.3.
