CHEMISTRY Y7 - Particles & Solutions
1 Seperating Mixtures
1.1 Chromatography
1.1.1 Separates different coloured substances - others are more soluble and travel further up the paper
1.2 Distillation
1.2.1 Separates 2 liquids or liquid from a solution - liquid with highest boiling point evaporates then condenses into another beaker
1.3 Filtration
1.3.1 Separates an insoluble solid from a liquid - liquid is the filtrate and the solid is the residue
1.4 Evaporation
1.4.1 Separates a soluble solid from a liquid - liquid evaporates at a certain temperature and the result is the solid
2 Solvents & Solutions
2.1 Solvent
2.1.1 A liquid substance in which a solute dissolves into
2.2 Solute
2.2.1 A solid substance that dissolves into a solvent
2.3 Solution
2.3.1 A mixture formed when a solute has dissolved into a solvent
2.4 Soluble
2.4.1 Describes a substance that will dissolve
2.5 Insoluble
2.5.1 Describes a substance that will not dissolve
2.6 Saturated
2.6.1 A solution in which no more solvent can be dissolved
3 States of Matter
3.1 Solid
3.1.2 > Regular Arrangement > Vibrate in a fixed position > Very close (cannot be compressed) > Strong bonds
3.2 Liquid
3.2.2 > Random Arrangement > Move around (can flow) > Close (cannot be compressed) > Weak bonds
3.3 Gas
3.3.2 > Random Arrangement > Move quickly in all directions > Far apart(can be compressed) > No bonds
3.4 Changes of State
3.4.1 Losing Energy Condensing: Gas to Liquid Stop moving quickly in all directions can only move around eachother Freezing: Liquid to Solid Stop moving around eachother and only vibrate on the spot
3.4.2 Gaining Energy Melting: Solid to Liquid Start moving around eachother Evaporating/ Boiling: Liquid to Gas Start moving quickly in all directions
4 Atoms, Elements, Compounds & Mixtures
4.1 Atoms
4.1.1 Atoms are an example of composite particles and are composed 3 sub-particles: electrons, protons, neutrons. They are like tiny balls
4.2 Elements
4.2.1 Atoms in a particular element are always the same as eachother Atoms in an element which are chemically joined are named molecules Oxygen Molecule: 2 oxygen atoms chemically joined Helium: Made of pure helium atoms
4.3 Compounds
4.3.1 Compounds contains atoms of 2+ more different elements that are chemically joined Water Molecule of compound: 1 oxygen & 2 hydrogen atoms chemically joined
4.4 Mixtures
4.4.1 Mixtures contain 2+ more different elements or compounds that are not chemically joined together Mixture of Elements Mixture of Compounds Mixture of Elements & Compounds
5 Density
5.1 Measure of Compactness
5.2 Density (g/cm3) = mass / volume
5.3 Solid
5.3.1 High Density - tightly packed
5.4 Liquid
5.4.1 Slightly High Density - close together
5.5 Gas
5.5.1 Low Density - far apart
5.6 Floating
5.6.1 When object is less dense than liquid
5.7 Sinking
5.7.1 When object is more dense than liquid
6.1 Cooling Curve
