ozone, O3 methane, CH4 oxygen gas, O2 All of these may be classified as A) ionic compounds B) covalent compounds C) inorganic compounds D) nonreactive compounds
They are all covalent compounds as they are made up of nonmetals. Ionic compounds are made up of a nonmetal and a metal. Some of the compounds are organic because they contain carbon so they cannot all be classified as inorganic. CH4, which is methane is reactive so this makes D false.
