- 3. CLASSIFICATION OF MATTER Composition of Matter MATTER
- 4. Matter Flowchart MATTER Homogeneous Mixture (solution) Heterogeneous Mixture Compound Element MIXTURE SUBSTANCE
- 5. Pure Substances Matter: Matter is classified as substances or a mixture of substances. Substance: A pure substance, or simply a substance, is a type of matter with a fixed composition A substance can be either an element or a compound.
- 6. Pure Substances Element matter composed of identical atoms EX: copper, gold, lead
- 7. Compounds Can you imagine yourself putting something made from a slivery metal and a greenish- yellow, poisonous gas on your food?
- 8. Compounds Table salt is a chemical compound that fits this description. Even though it looks like white crystals and adds flavor to food, its components—sodium and chlorine—are neither white nor salty.
- 9. Pure Substances Compound matter composed of 2 or more elements in a fixed ratio Cannot be separated by a physical means properties differ from those of individual elements EX: salt (NaCl), water, chalk
- 10. o A mixture, such as the pizza or soft drink shown, is a material made up of two or more substances that can be easily separated by physical means. Mixtures
- 11. Mixtures Variable combination of 2 or more pure substances. Homogeneous Mixture (Solution) even distribution of components very small particles particles never settle EX: saline solution, fresh pickle juice, vinegar, soda
- 12. Heterogeneous Mixtures Unlike compounds, mixtures do not always contain the same proportions of the substances that make them up. A mixture in which different materials can be distinguished easily is called a heterogeneous mixture.
- 13. Mixtures Heterogeneous Mixture uneven distribution of components colloids and suspensions EX: granite, permanent press fabric
- 14. Colloids Milk is an example of a specific kind of mixture called a colloid. A colloid is a type of mixture with particles that are larger than those in solutions but not heavy enough to settle out.
- 15. Mixtures Colloid medium-sized particles Tyndall effect - particles scatter light (looks cloudy) particles never settle EX: milk, fog, gelatin, paint,
- 16. Tyndall Effect Because of the Tyndall effect, A light beam is Scattered by the Colloid suspension On the left, but Passes invisibly Through the solution On the right.
- 17. Mixtures Suspension large particles particles scatter light particles will settle (needs to be shaken) EX: Italian salad dressing (oil, vinegar, and spices), a river delta, pond
- 18. Suspensions • The table summarizes the properties of different types of mixtures.
