1.1 States of matter, changes of state and state symbols
1.1 Elements, compounds, mixtures
Understandings:
Atoms of different elements combine in fixed ratios to form compounds, which have different properties from their component elements. Mixtures contain more than one element and/or compound that are not chemically bonded together and so retain their individual properties. Mixtures are either homogeneous or heterogeneous. Applications and skills: Explanation of observable changes in physical properties and temperature during changes of state. 
1.1 Physical and chemical changes
1.1 Balancing chemical equations
1.2 Relative atomic mass and molecular mass

Obtaining and using experimental values to calculate the molar mass of a gas from the ideal gas equation.
1.3 Deviation from ideal gas behaviour
1.3 Concentration of solutions
Understandings:
The molar concentration of a solution is determined by the amount of solute and the volume of solution. Applications and skills: Solve problems involving molar concentration, amount of solute and volume of solution. Units of concentration to include: g dm3, mol dm3 and parts per million (ppm). 
This video covers how to calculate the concentration of a solution using a thermometric titration.
This video covers how to determine the percentage calcium carbonate in an egg shell using a back titration.
