This metal is mined as zinc compounds, one of which is zinc carbonate. asked Oct 7, 2018 in Chemistry by Afreen ( 30.7k points) oxidation-reduction (Don’t forget … Thus, the carbon must have an oxidation # of +4. The oxidation state, sometimes referred to as oxidation number, describes the degree of oxidation (loss of electrons) of an atom in a chemical compound.Conceptually, the oxidation state, which may be positive, negative or zero, is the hypothetical charge that an atom would have if all bonds to atoms of different elements were 100% ionic, with no covalent component. The usual oxidation number of hydrogen is +1. •For Example: C (s) + O2 (g) → CO2 (g) and 2H2 (g) + O2 (g) → 2H20 (l) •These reactions are classified as redox because they involve the oxidation of carbon and hydrogen and the reduction of oxygen.
