Classification of Matter

  1. Fill in and memorize the Flow Chart below describing how to classify matter. Include both the classification type, a short description of each, and one example for each of the four main classifications:


  1. Matching:
  1. Homogeneous Mixturei. Matter composed of a simple substance that cannot be broken
  2. Compound down any further
  3. Elementii. Matter composed of more than one substance that looks different
  4. Heterogeneous Mixture throughout

iii. Pure substance created chemically that has different properties than

the substances that form it

iv. Matter composed of more than one substance that looks different

throughout.

v. These are given symbols like ‘Ar’, ‘Zn’, ‘W’, and ‘Xe’ and are arranged

in a table called the Periodic Table

  1. Identify the following as either an ELEMENT (E), COMPOUND (C), HOMOGENEOUSMIXTURE (S) or HETEROGENEOUSMIXTURE (H)

  1. Vinegar and Oil
  2. Dry Ice (solid carbon dioxide (CO2))
  3. Brass allow (Cu and Zn)
  4. Table Salt (NaCl)
  5. Oxygen gas (O2)
  6. Salt dissolved in water
  7. Chex Mix
  8. Gold Bracelet (Au)
  9. Clear apply juice
  10. Sugar (C12H22O11)
  11. Sugar dissolved in water
  12. Air

  1. Separation Techniques:
  1. Define Filtration: Separation of a solid from a mixture and/or separation of 2 solids based on size
  1. What is the main difference between the parts of the mixture that allow them to be separated by filtration? State of matter and/or size
  1. Define Distillation: Separation of 2 or more liquids based on differences in their boiling point
  1. What is the main difference between the parts of the mixture that allow them to be separated by distillation? boiling point
