List the types of heterogeneous mixtures and homogeneous mixtures we discussed
Heterogeneous: suspension, colloid, aerosol
Homogeneous: solution
6 neutrons
Describe the difference between heterogenous and homogeneous mixtures
Heterogenous mixtures are not uniformed when mixed together. You can separate the materials. Homogenous mixtures are uniformed together. When you mix two materials, they become one and blend together. You cannot separate the materials.
