Mo7-L1c: What is a Mixture?





                                                    Matter
                                    Anything that has mass and takes up space.
                                          Most matter is made up atoms
                                  Two classif cations of matter: Substances and
                                                   Mixtures.


                                                Substances
                         Made up of one or more types of atoms in the same combinations.
                              Two types of substances: Elements and Compounds.



                            Elements                                     Compounds

                  • Made of only one type of atom          • Made of two or more types of atoms bonded
                  • Organized on the periodic table.                       together.
                • Elements have a chemical symbol.        • Properties are different from the elements that
                                                                          make it up.
                                                               • Compound have chemical formulas.




                                                              Mixtures are separated into substance by
                                                              physical methods: Filtering; Boiling point.
                                                                     melting point; magnetism.




                                                     Mixtures
                             Made up of two or more substances that are not bonded together.
                                       Combinations of the substances can vary.
                               Two types of mixtures: Heterogeneous and Homogeneous


                        Heterogeneous                                      Homogeneous
             • Two or more substances unevenly mixed             • Two or more substances evenly mixed
            • Different substances are visible by unaided      • Different substances cannot be seen even
                       eye or microscope.                                  by a microscope.
