The oxidation number of diatomic and uncombined elements is zero. The oxidation number of a free element is always 0. For the following reaction KClO4 rightarrow KCl + 2O2 assign oxidation states to each element o... For the following reaction KClO4 rightarrow KCl + 2O2 assign oxidation states to each element on each side of the equation. Ca2+, HF2^-, Fe4[Fe(CN)6]3, NH4NO3, so42-, ch3cooh, cuso4*5h2o). The answer is B, +7. To calculate oxidation numbers of elements in the chemical compound, enter it's formula and click 'Calculate' (for example: Use oxidation states to identify the element that is being oxidized in the following redox reaction: Cu(s)+2 H 2 S O 4 (aq) → CuS O 4 (aq)+S O 2 (g)+2 H 2 O(l) chemistry KTF-Split, 3 Mar. Any free element has an oxidation number equal to zero. The oxidation number for the calcium in CaSO4 is 2+, the oxidation number for oxygen is 2-, and the oxidation number for sulfur is 6+. Expert's Answer. (5) Hydrogen always have a charge of +1 if it is bonded with a non-metal (as in the case of #HCl#) and always have a -1 charge if it is bonded with a metal (as in #AlH_3#). In hydrogen peroxide H 2 O 2, the oxidation number of O is -1 and the range of the Oxidation number that O can have are from O to -2 can sometimes also attain the oxidation numbers +1 and +2.
