Classifying Matter

From-http://dbhs.wvusd.k12.ca.us/webdocs/Matter/2.2ElementsAndCompounds.html

Matter-Everything that has physical existance. Therefore, anything that has mass and takes up space.

How do we classify matter?

Is only one chemical substance present in the sample being considered?"

YES-Pure Substance

No-Mixture             

All pure substances can be separated into two categories by asking the question "Can the sample be further decomposed by chemical means?" (Notice we are ignoring mixtures for the moment.)

YES- Compound

NO-Element   

If you have a mixture...Is the sample of constant composition?"

Yes-Homogeneous Mixture

No-Heterogeneous Mixture

Classify these as Element, Compound, Heterogeneous Mixture or Homogeneous Mixture.
