Transcript of "Classifications of Matter"

  1. 1. Classification of Matter •Now that we have defined chemical and physical properties of matter, we can use that to help us classify it.
  2. 2. Matter Mixture Pure Substance ElementCompoundHeterogeneous Mixture Homogeneous Mixture Can be separated physically Cannot be separated physically Can see the parts Cannot see the parts Can be separated chemically Cannot be separated Most impure Most pure
  3. 3. Classification of Matter • Pure Substance – Matter that has only 1 set of chemical and physical properties. Example: Pure water always has the exact same chemical and physical properties under the same conditions. If water ever tastes different then it isn’t pure water; it fits into our next category.
  4. 4. Classification of Matter • Mixture – Two or more pue substances mixed together. Each substance in the mixture retains its own set of chemical and physical properties. Example: Copper and Zinc can be mixed together to produce brass.
  5. 5. Classification of Matter Mixture Example: Copper and Zinc can be mixed together to produce brass. Even though it may look different, it is still copper and zinc. Each metal retains its own properties like melting point.
  6. 6. Classification of Matter • Mixture – Two or more pure substances mixed together. Each substance in the mixture retains its own set of chemical and physical properties. Unlike pure substances, mixtures can always be separated by physical means. How could we separate the copper and zinc back out?
  7. 7. Mixtures • Mixture – Two or more pure substances mixed together. Each substance in the mixture retains its own set of chemical and physical properties. If a sample of sand contains iron and salt, how could you separate them from the other minerals?
  8. 8. Mixtures • Some mixtures are more pure than others. • Heterogeneous mixture – Uneven distribution of substances. (Very impure) - You can see the different parts. Examples: Sand Granite Wood
  9. 9. Mixtures • Some mixtures are more pure than others. • Heterogeneous mixture – Uneven distribution of substances. (Very impure) - You can see the different parts. Examples: Milk Blood
  10. 10. Mixtures • Homogeneous Mixture – Components are evenly mixed. (More pure than heterogeneous) Salt water contains salt and water, but are mixed all the way to the atomic level - Cannot see the parts. , but it can still be separated by physical means. Seawater distillation plant
  11. 11. Pure Substances • Pure substances can also be divided into 2 categories: compounds and elements.
  12. 12. Pure Substances • Compound – Two or more elements chemically bonded together. Examples: Carbon Dioxide (CO2) Water (H2O) Salt (NaCl) Sucrose (C12H22O11)
  13. 13. Pure Substances • Compounds have only 1 set of properties. They cannot be separated by any physical process. - Can only be separated by a chemical reaction. Water can be separated into Hydrogen and Oxygen by a process called Electrolysis.
  14. 14. Pure Substances • Elements – Substances made up of only one type of atom. - Cannot be separated by any physical OR chemical process. Examples: Carbon Helium Gold
  15. 15. Matter Mixture Pure Substance ElementCompoundHeterogeneous Mixture Homogeneous Mixture Can be separated physically Cannot be separated physically Can see the parts Cannot see the parts Can be separated chemically Cannot be separated Most impure Most pure
