|
The energy from the temperature is being used to break apart the bonds in the particles |
| When there is a change of state, the temperature stays ______ | Constant |
| What is a pure substance? | A substance with a composition that: Cannot be changed Is the same in all parts of the substance (all the molecules NOT PARTICLES are the same) |
| True or False? A pure substance can be separated using physical methods whereas a mixture cannot | False, it's the other way round |
| What does a mixture contain? | Elements and/or compounds that are NOT chemically joined, such as sand |
| What is chromatography used for? | Separating the components of dyes/ink/paint/food colouring etc. |
| Why does chromatography work? | The different components have different solubility, meaning that they are separated due to the solubility |
| What is a solute? | A substance that dissolves into a solvent |
| What is a solvent? | A substance that a solute dissolves in |
| Chromatography Mobile Phase | The solvent |
| Chromatography Stationary Phase | The paper |
| How do you calculate Rf? | Distance Travelled by the Substance -------------------------------------------------- Distance Travelled by the Solvent |
| Rf is always less than | 1 |
| Name labels 1-8 | 1 - Bunsen Burner 2 - Solution 3 - Gas 4 - Thermometer 5 - Condensor 6 - Cooling Water In 7 - Cooling Water Out 8 - Distillate |
| 3 Parts of Purifying Water and what they do | Water goes into: 1. Sedimentation Tank to get rid of large rocks 2. Filtration Tower to get rid of any other molecules, dirt etc 3. Chlorination Tank to get rid of bacteria |
