  1. Classification of Matter

  2. Matter Mixtures Pure Substances Heterogeneous Mixtures Homogeneous Mixtures Elements Compounds Have you thought about all of the objects that matter can be broken down into? Physical Changes

  3. Pure Substances: MATTER THAT IS THE SAME THROUGHOUT: • Same Composition • Same Physical and Chemical Properties

  4. Pure Substances Elements Compounds Chemical Changes

  5. Elements are: - The simplest form of matter. - Can not be broken down into simpler substances. Examples: Gold, Oxygen, and Platinum

  6. Everything in the universe is made up of elements. Today over 114 elements have been discovered. They combine chemically to form compounds

  7. Compounds are: • Combinations of two or more different elements combined chemically • Most of the matter in the universe are compounds • Examples: Water, Salt, and Aspirin

  8. Mixtures: COMBINATION OF TWO OR MORE SUBSTANCES: There are 3 types of Mixtures: 1. Solutions 2. Colloids 3. Suspensions

  9. Mixtures Heterogeneous Mixtures Colloids and Suspensions Homogeneous Mixtures Solutions

  10. Homogeneous “Homo-”: the same Mixtures Composition is the same throughout Examples: lemonade, gasoline, steel, salt water Heterogeneous “Hetero”-: different Mixtures Composition is inconsistent Examples: orange juice, pizza, dirt, blood, milk Homogeneous VS Heterogeneous

  11. Colloids ● Colloids have particles that are small to medium in size. ● The particles in a colloid do not settle out. ● Colloids have a positive Tyndell Effect

  12. What is a Tyndell Effect? • A Tyndell Effect is when dispersed colloid particles are large enough to scatter light.

  13. Colloids ● Colloids appear cloudy. ● The particles in a colloid are not filtered out. ● Examples of colloids are: milk, mayonnaise, and fog

  14. Suspensions • Suspensions have medium to large sized particles. Sometimes you can see them with your eyes. • Suspensions settle out when they are left alone. • Suspensions have a positive Tyndell Effect. • Suspensions may appear cloudy or chunky.

  15. Suspensions • Suspensions have particles that are large enough to be filtered out (they can be caught by a filter). • Examples of suspensions are: - Italian salad dressing -Snow globes -Smoke -Dust in the air -Orange Juice

  16. Solutions ● Solutions are made when a solute (like sugar) is dissolved into a solvent (like water). ● Solutions have tiny particles that you can’t even see with a microscope. ● Solutions do not settle out when they are left alone. ● Solutions do not have a positive Tyndell Effect. ● Solutions are clear (not necessarily colorless).

  17. Solutions ●Particles are not filtered out. ●Examples of solutions are: - Soft drinks - Tea - Windex
