|
Pure substances and mixtures
|
|
|
Define pure substances.
|
They contain only one substance (every individual item in the sample is essentially the same as every other item in the sample). It cannot be separated into individual components by any physical means.
|
|
|
Define mixtures.
|
They are a combination of two or more substances. Each substance in the mixture retains its own identity and properties. It can be separated into the component substances by some physical separation. The ratios of the components are not fixed.
|
|
|
Name the two categories of pure substances.
|
Elements and compounds.
|
|
|
Name the two categories of mixtures.
|
Homogeneous and heterogeneous.
|
|
|
Define elements.
|
They are any of the 109 items found on the periodic table of elements. These are the basic building blocks of all matter. The “chemical alphabet”.
|
|
|
Define compounds.
|
They are the combinations of two or more elements to produce a new substance with its own unique characteristics and properties. The elements combined to make the compound cannot be separated by any physical means. The ratios of the components are fixed.
|
|
|
What is a homogeneous mixture?
|
It is a mixture that is the same throughout (no region of the sample is in any way distinguishable from any other region)
|
|
|
What is a heterogeneous mixture?
|
It is a mixture that has distinguishably different regions (there are regions of the sample that are significantly and distinguishably different from other regions).
