Pure SubstancesElementcomposed of identical atomsEX: copper wire, aluminum foil
Pure SubstancesCompoundcomposed of 2 or more elements in a fixed ratioproperties differ from those of individual elementsEX: table salt (NaCl)
Pure SubstancesLaw of Definite CompositionA given compound always contains the same, fixed ratio of elements.Law of Multiple ProportionsElements can combine in different ratios to form different compounds.
Pure SubstancesFor exampleTwo different compounds, each has a definite composition.
MixturesVariable combination of 2 or more pure substances.HeterogeneousHomogeneous
