Notes
_____________________________________________________________
_________________ A pure substance can be either an __________________ or a ______________
_________________ and consists of only ______________ component with definite physical and
_________________ chemical properties and a definite _____________________.
_________________ A mixture consists of _______________substances that are NOT chemically
_________________ combined and can be separated by ______________________ means. The
_________________ substances in a mixture _____________ their individual properties.
Mixtures can further be classified as ____________________ or
________________________ mixtures.

_________________ Homogeneous mixtures there are no visible parts and it is uniform in
_________________ Composition.
_________________ Homogeneous Mixtures : Vinegar, Clear Air, Salt water, brass

Notes
____________________ ____________________ Techniques can be used to
Separate mixtures.
____________________- solid part is trapped by filter paper and the liquid part
Runs through the paper.
Vaporization: where the liquid portion is evaporated off to leave ___________.
______________________- when liquid is poured off after the solid has
Settled to the bottom
Centrifuge- machine that spins a sample very quickly so that components with
Different _________________ will separate
___________________________- used to separate mixtures because different
Parts move quicker on paper than others
Applying the Concepts Learned:
Using the information in the notes, you will be able to determine what type of matter these
examples are. Next to the example, write the abbreviation for one of the following: element (E),
compound (C), heterogeneous mixture (hetero), or homogeneous mixture (homo)
