How do I balance the chemical equation …
19/7/2010· Let''s look at cobalt (III) oxide. Cobalt (III) means its cobalt ion with valency of 3 and since metals form positive ions, this is Co3+ ion. Oxide ion = O2- Thus cobalt (III) oxide should have the chemical formula Co2O3 (swop the valencies to get the formula of the compound formed) Balanced chemical equation: 4Co + 3O2 --> 2Co2O3 Hope this helps.
