Matter and change

  1. 1. Matter and Change Mrs. Coyle Chemistry
  2. 2. A) Classification of Matter
  3. 3. Some Criteria for the Classification of Matter  Properties  State (solid, liquid, gas)  Composition
  4. 4. Properties Intensive -Do not depend on amount of matter. Extensive -Depend on amount of matter.
  5. 5. Intensive and Extensive Properties Sulfur
  6. 6. Properties Physical: observed without without changing the composition of the substance. Chemical: the ability of a substance to undergo a specific chemical change
  7. 7. Examples of Physical Properties Color, odor, hardness, density, melting point, boiling point, state, solubility.
  8. 8. (Pure) Substance Matter that has a uniform and definite composition. Elements Compounds
  9. 9. Mixture: a physical blend of two or more substances that are not chemically combined. Homogeneous Heterogeneous
  10. 10. B) Mixtures
  11. 11. Mixture A physical blend of two or more substances.
  12. 12. Note: Mixtures can be physically separated. Mixtures exhibit physical properties similar to the components of the mixture.
  13. 13. c) Elements and Compounds
  14. 14. Elements The simplest substances. Can not be separated into simpler substances. Building blocks of all matter. More than 100 known elements. Represented by chemical symbols.
  15. 15. Compound A substance that contains two or more elements chemically combined. Compounds have different properties from the individual substances. (Ex: H2O)
  16. 16. Substance or mixture? If composition is fixed and may not changesubstance
