| anything that has mass and volume |
|
| made up of only one type of atom or molecule, fixed composition and distinct properties, cannot be separated by physical means |
|
| substance that cannot be decomposed into simpler substances |
|
| substance containing more than one element, chemically combined always contains definite or constant proportions of the elements by mass |
|
| Matter that is made of two or more substances in which each substance retains its own chemical identity. |
|
| mixture in which the substances are uniformly distributed. aka SOLUTION |
|
| A mixture in which the substances are not uniformly distributed |
|
| heterogeneous mixture of a solvent-like substance with particles that slowly settle out. particle size are large and more dense when compared to water molecules |
|
| heterogeneous mixture consisting of particles intermediate in size between those in solutions and those in suspensions |
|
liquid that passes through filter paper |
| |
bits of solid left of filter paper |
| |
| used to separate suspensions. only works if particles are large enough to get “stuck” in filter paper |
|
| process used to separate liquids and solids when particles are too small and pass through filter paper. the larger particles are pulled to the outside |
|
| pouring off the top layer . immiscible liquids only |
|
| used to obtain the solute from the solution |
|
| |
| |
| used to separate miscible liquids. heat the mixture. used when you want both things or what has lowest boiling point . goes from liquid- to water vapor (steam) into liquid (from cold around tube) |
|
| A technique in which molecules in a mobile phase are separated because of their different affinities for a stationary phase |
