What is the oxidation number of carbon in CO2? •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. Since oxygen is in group 6 on the periodic table, its valency is 2− and hence so is its oxidation number. In CO2 the oxidation number for oxygen is -2. :). Carbon and oxygen have the oxidation states of 0 in their elemental forms (C and O2, respectively). Carbon monoxide (CO) is a colorless, odorless, and tasteless flammable gas that is slightly less dense than air.It is toxic to animals that use hemoglobin as an oxygen carrier (both invertebrate and vertebrate) when encountered in concentrations above about 35 ppm, although it is also produced in normal animal metabolism in low quantities, and is thought to have some normal biological functions. 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. hence when ethane burn in excess of oxygen then it's oxidation number change from -3 to 2.O This Demonstration enumerates the possible oxidation states of carbon in a number of compounds containing one or two carbon atoms (colored gray) bonded to hydrogen atoms (white) and oxygen atoms (red). hydrogen(I) oxide .
