16. 6. Mixtures may be heterogeneous or homogeneous.
2 Main Types of Mixtures
6. Mixtures may be heterogeneous or homogeneous.

17. Heterogeneous Mixtures
7. In a heterogeneous mixture, which is not the same throughout, the parts of the substances can be visibly seen.

18. Homogeneous Mixtures
8. In a homogeneous mixture, the mixture looks the same throughout. 9. The substances are evenly mixed and you cannot see a difference in the parts of the mixture. 10. The particles of the substances are so small that they cannot be easily seen. Another name for a homogeneous mixture is a solution. Saltwater Milk
