Answer» To balance the NUMBER of iodine atoms, HI is multiplied with 2.Iodine is oxidized. Its OXIDATION state changes from −1 to 0. Net increase is +2.Sulphur is reduced. Its oxidation state changes from 6 to −2. Net decrease is 8.To balance the net increase and net decrease in the oxidation number, factor 4 is used. Thus, coefficients of HI and I 2 are multiplied by 4.To balance OXYGEN atoms, FOUR water molecules are required on the right.Thus, x=8, y=4 and z=4.Explanation:please mark me as branliest |
