                                                                                 What are Mixtures?

                                                                    The substances that make up a mixture are
                                                                        blended but not chemically bonded.

                                                                      Homogeneous mixtures have the same
                                                                     makeup of substances throughout a given
                                                                                     sample.









                To separate a heterogeneous mixture, you use
                differences in the physical properties of the parts.
