Key Vocabulary:. Mr. McMartin. Beta Science. Mixtures. Mixture: a combination of two or more substances that are not chemically combined.. Can only become a mixture if they do not react to form a compound.. There are no chemical changes that happen in a mixture.. Mixtures may be separated by many different techniques based on differing physical and/or chemical properties. Sorting. Simply picking apart the different components. This can be easy and obvious…. Mixtures. Solutions are a type of mixture, so to understand solutions, first we have to know what a mixture is…. A . mixture. is a combination of two or more substances.

Cannot be broken down and retain its properties.. Has a fixed composition.. Every sample of a pure substance has EXACTLY the same composition AND exactly the same characteristics - homogeneous. Mixtures. A combination of two or more substances that do not combine chemically, but remain the same individual substances; can be separated by physical means. Two types:. Heterogeneous. Homogeneous. Chapter 5. Ex:. Melting. Freezing. Boiling/evaporation. Condensation. Sublimation. Dissolving. Bending. Crushing. Breaking. Chopping. Filtration. distillation. Physical change.
