Classifying Matter
  1. Pure Substances
    1. Element
      1. Cannot be broken down Same composition One type of atom
      2. Compound
        1. Made of two or more pure substances Can be broken down Different types of atoms
        2. Every sample of a given substance has the same properties because a substance has a fixed, uniform composition
        3. Mixtures
          1. Homogeneous
            1. you can't tell the difference between substances
              1. Solution
                1. Can separate by: Distillation - separates materials based on boiling points,
                  1. don’t reflect light, doesn’t form layers, can’t filter it
                2. Heterogeneous
                  1. you can tell the difference between substances
                    1. Suspension
                      1. Separate over time into layers, (water and sand) scatters light, if in water
                        1. Can separate by: Filtration - separates materials based on particle size
                      2. A mix of substances to form one substance
                        1. Colloid
                          1. Bigger particles than solution, smaller than suspension, do not separate into layers, reflects light (fog)
