Classifying Matter

 

 

Matter-Everything that has physical existence. 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

 

 

 

Alloy- a homogeneous metal mixture

 

 

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