Transcript

  • 1. Composition of Matter
  • 2. <ul><li>All matter is made up of atoms. </li></ul><ul><li>Elements - when all the atoms in the matter are the same. </li></ul><ul><li>There are 118 elements. </li></ul><ul><li>Ex: Carbon and Oxygen </li></ul>
  • 3. Compounds <ul><li>Compounds - matter that is made up of 2 or more combined elements. </li></ul><ul><li>Compounds look different than the elements that make them up. </li></ul>
  • 4. Compound Ex: <ul><li>Ex: H & O = H 2 O </li></ul><ul><li>C & O = CO 2 </li></ul><ul><li>C,H & O = C 6 H 12 O 6 </li></ul>
  • 5. Substance <ul><li>Substance - matter that is either an element or a compound. </li></ul>
  • 6. Mixture <ul><li>Mixture - material that is made up of 2 or more substances that can be separated physically. </li></ul>
  • 7. 2 Types of Mixtures <ul><li>Heterogeneous </li></ul><ul><li>Homogeneous </li></ul>
  • 8. Heterogeneous Mixtures <ul><li>Heterogeneous Mixture- mixture that is unevenly mixed. </li></ul><ul><li>You can see the stuff in the mixture. </li></ul>
  • 9. Heterogeneous Mixture Ex:
  • 10. Homogeneous Mixture <ul><li>Homogeneous Mixture- mixture that is evenly (uniformly) mixed. </li></ul><ul><li>Homogeneous Mixtures are also called solutions . </li></ul>
  • 11. Homogeneous Mixture Ex:
  • 12. Matter Substance Mixture Element Compound Homogeneous Heterogeneous
  • 13. Colloid <ul><li>Colloid - a heterogeneous mixture that never settles. </li></ul><ul><li>Ex: milk or fog </li></ul>
  • 14. Suspension <ul><li>Suspension - heterogeneous mixture that contains a liquid where visible particles settle. </li></ul>
  • 15. Suspension Examples
  • 16. Tyndall Effect <ul><li>Tyndall Effect- the scattering of light by particles in a mixture. </li></ul>
  • 17. Tyndall Effect Ex:
  • 18. What do you have? YES YES NO Does it scatter light? YES NO NO Can it be filtered? YES NO NO Does it settle? Suspension Colloid Solution
