6: Mixtures Definition: combination of two or more substances that are physically combined. The identity of a mixture does not change. Solution is a well mixed mixture particles are small and dissolved. A heterogeneous mixture is a
7: in which the substances are not evenly mixed. A suspension is also a heterogeneous mixture. A homogeneous mixture is a substance in which the components are evenly mixed. A colloid is a mixture in which particles are mixed but NOT dissolved.
