- 15what is an elementan element is a substance that is made up of one atom it cannot be broken down into anything simplier
- 16what is a compounda compound is a substance made up of two or more atoms chemically bonded together
- 17what is a mixturea mixture contains two or more types of substance together but not chemically bonded
- 18what is a pure substancea pure substance contains a single element or compound and are not mixed with any other substance
- 19what is an impure substancean impure substance contains a mixture of different substances
- 20what does the term insoluble meana solid that will not dissolve in a liquid
- 21what does the term solute meana solid that can dissolve in a liquid
- 22what does the term solvent meanthe liquid that the solid dissolves in
- 23what does the term solution meanthe solute and the solvent
- 24what is filtrationfiltration is used to separate an insoluble solid from a liquid
- 25what is the filtratethe solution that passes through the filter paper
- 26what is the residuethe insoluble solid that remains in the filter paper
- 27what is evaporationevaporation is used to separate a dissolved solid from a solvent
- 28what is crystillisationcrystallisation also is used to seperate a dissolved solid from a solvent
- 29what is simple distillationdistillation is used to separate the solvent from the solution and it is also used to separate two miscible liquids
- 30what does the term miscible liquids meanliquids that mix together
- 31what does the term immiscible meanliquids that do not mix together
- 32what is paper chromatographypaper chromatography seperates the different soluble substances in a mixture
- 33what happens when chromatography paper is dipped into the solventthe solvent travels up the paper
