Oxidation number (also called oxidation state) is a measure of the degree of oxidation of an atom in a … Magnesium is being oxidized and nitrogen is being reduced. In the ion-electron method (also called the half-reaction method), the redox equation is separated into two half-equations - one for oxidation and one for reduction. To balance a redox equation, begin by finding the oxidation states of the reactants and the products (CrO4)^-2 4 oxygens contribute -8 charge, overall charge is -2, so the chromium contributes +6 - this is the ox state and this changes to Chromium^+3 - a change of 3 electrons . In the second one S goes from 4+ to 6+ (loss of electrons) and O goes from neutral (in the O2) to 2-. reduction. You will never get SO3 out of just O2 and water. Instead of SO3 . H: +1 I: -1.
