A mixture which has uniform composition and properties throughout.
A mixture is made when two or more substances are combined without the formation of chemical bonds. Mixtures can be returned to their original components by physical separation methods, such as distillation or sieving, while substances held together by chemical bonds can only be returned to their original components via chemical reactions.
Examples of homogeneous mixtures are: any gases at equilibrium in a closed space; the hydrocarbons in gasoline; a sugar solution in water at equilibrium; vinegar dissolved in water.
