Compound: a substance made up of two or more elements that are chemically bonded together
Covalent bond: bond between two atoms in which both atoms share one or more electrons
6 of 23
Cracking: used in the oil industry to break down hydrocarbons into smaller and more useful ones
Distillation: the separation of a liquid from a mixture by evaporation and condensation
