  • 1. Matter
    • Classification of Matter
      • Matter Flowchart
      • Pure Substances
      • Mixtures
  • 2. Matter Flowchart MATTER Can it be physically separated? Homogeneous Mixture (solution) Heterogeneos Mixture Compound Element yes no Is the composition uniform? yes Can it be chemically decomposed? Yes No No MIXTURE PURE SUBSTANCE
  • 3. Matter Flowchart
    • Examples:
      • Graphite
      • Pepper
      • Sugar (sucrose)
      • Paint
      • Soda
      • Element
      • Hetero. mixture
      • Compound
      • Hetero. mixture
      • Solution
  • 4. Pure Substance
    • A Pure substance is one which is made up of only one kind of particles
    • All Elements and Compounds are Pure substance
    • EX : Oxygen, nitrogen, iodine, iron,
    • silicon, silver, gold , etc.
  • 5. Pure Substances
    • Element
      • Composed of identical atoms
      • Only one kind of atoms
      • EX : copper wire, aluminum foil
  • 6. Pure Substances
    • Compound
      • Composed of 2 or more elements in a fixed ratio
      • Properties differ from those of individual elements
      • EX : table salt (NaCl)
  • 7. Pure Substances
    • Law of Definite Composition
      • A given compound always contains the same, fixed ratio of elements.
    • Law of Multiple Proportions
      • Elements can combine in different ratios to form different compounds.
  • 8. Pure Substances
    • For example…
    Two different compounds, each has a definite composition.
  • 9. Mixture
    • A Mixture contains two or more different kinds of particles (pure)
    • All mixtures Are Impure
  • 10. Mixtures
    • Variable combination of 2 or more pure substances.
    Heterogeneous Homogeneous
  • 11. Mixtures
    • Homogeneous/Solution
      • Uniform throughout
      • Very small particles
      • No Tyndall effect
      • Particles don’t settle
      • EX : rubbing alcohol
    Tyndall Effect
  • 12. Mixtures
    • Heterogeneous
      • Not uniformed throughout
      • Medium/large-sized
      • particles
      • Tyndall effect
      • particles may or
      • may not settle
      • EX : milk, Blood
  • 13. C. Mixtures
    • Examples:
      • Muddy water
      • Saltwater
      • Salad Dressing
      • Blood
      • Water + Milk
      • Heterogeneous
      • Homogeneous
      • Heterogeneous
      • Heterogeneous
      • Homogenous
