MixturesCompounds Components are elements, compounds, or both Components are elements Components keep their original properties Components lose their original properties Separated by physical means Separated by chemical means Formed using any ratio of components Example: Cookie dough can have a 5g or 50g of chocolate chips. Formed using a set ratio of components Example: H 2 O must have two hydrogen atoms and one oxygen atom.
