  1. 1. scatters light, different sized particles, can’t filter out, don’t separate
  2. 2. some properties change, but the substance remains the same.
  3. 4. substances are so evenly distributed that it is difficult to distinguish one substance from another
  4. 5. more energy is required to break the bonds in the reactants than is released by the formation of the products.
