  3. MIXTURE PURE SUBSTANCE yes no yes no Is the composition uniform? Can it be decomposed by chemical means? A. Matter Flowchart MATTER yes no Can it be separated by physical means? Homogeneous Mixture (solution) Heterogeneous Mixture Compound Element

  4. MATTER Ch. 9 - Classification of Matter II. Composition of Matter (p.246-250) Matter Flowchart Pure Substances Mixtures

  5. B. Pure Substances • Element • matter composed of identical atoms • EX: copper

  6. B. Pure Substances • Compound • matter composed of 2 or more elements in a fixed ratio • properties differ from those of individual elements • EX: salt (NaCl)

  7. C. Mixtures • Variable combination of 2 or more pure substances. • Homogeneous Mixture (Solution) • even distribution of components • very small particles • particles never settle • EX: saline solution

  8. C. Mixtures • Heterogeneous Mixture • uneven distribution of components • colloids and suspensions • EX: granite

  9. C. Mixtures • Colloid • medium-sized particles • Tyndall effect - particles scatter light (looks cloudy) • particles never settle • EX: milk

  10. C. Mixtures • Suspension • large particles • particles scatter light • particles will settle (needs to be shaken) • EX: fresh-squeezed lemonade
