Title: Mixtures, Elements, and Compounds (Chap. 4)


1
Classifying Matter
2
  • Classifying a substance by physical properties
    (state, boiling point, color, density) is not
    specific enough
  • one substance can exist in more than one phase
  • example ice (solid), water (liquid), and steam
    (gas) are all made of H2O which is called
    dihydrogen monoxide
  • many substances have the same density, color
  • different substances can all exist in the same
    phase
  • salt, gold, sand, and ice are all solids
  • It is often better to classify substances by what
    they are made out of and their chemical properties

3
Matter

Mixtures
  • Heterogeneous Mixture
  • does not look the same throughout
  • not mixed very well
  • can often see different particles unevenly mixed
  • often can be easily separated
  • examples salad dressing, rocks, concrete

7
  • Homogeneous Mixture
  • looks the same throughout
  • mixed very well
  • often cant see different particles mixed
    together
  • often difficult to separate
  • examples steel, milk, salt water, Kool Aid

  • Most common kind is a solution
  • always has a substance that is dissolved in
    another substance
  • the substance that is dissolved is called the
    solute
  • the substance that does the dissolving is the
    solvent
  • examples salt water, alloys (solids dissolved in
    solids)
  • a substance that dissolves in another substance
    is soluble if it cant, it is insoluble
