|
homogeneous mixture
|
no visibly different parts. Also called solution.
|
|
|
Examples of Homogeneous.
|
Homogenized milk, Koolaid, vinegar, most nail polishes
|
|
|
Flitration
|
commonly used to separate solids from liquids.
EX Water + ethanol + food coloring. |
|
|
distillation
|
separeation based on difference in boiling points. Separation of liquid and liquid.
|
|
|
electrolysis
|
separeation of many mixtures by different charges.
|
|
|
chromatogoraphy
|
separation based on charge, polarity, 3-D shape, mass, etc. Ex. paper chromatography.
|
|
|
Characteristics of Compounds
|
The elements making up a compound are in definite proportion by mass always.
EX water is always 11.2 % hydrogen and 88 % oxygen |
|
|
2 Characteristics of compounds
|
The chemical and physical properties of a compound differ from those of its consituents.
EX. Hydrogen is flammable, water is a liquid at room temperature, hydrogen and oxygen are gases. |
|
|
3rd Characteristics of Compounds
|
Compounds can be formed from simpler substances by chemical change and they can be decomposed into simpler substances by chemical change.
