Part of the AQA GCSE Combined Science curriculum.
AQA GCSE Combined Science 5.3 Quantitative Chemistry is a step-by-step online learn guide for GCSE students in Years 10 and 11, mapped to the AQA specification (AQA GCSE Combined Science: Trilogy (8464) – 5.3 Quantitative chemistry). It covers conservation of mass and balanced equations, relative formula mass, mass changes when a gas is involved, chemical measurements and uncertainty, moles and the Avogadro constant, reacting masses and limiting reactants and concentration of solutions, then brings it all together with mixed retrieval and exam practice.
There are 23 short steps of about 15 minutes (roughly 6 hours of learning), each made of bite-size explanations with key words, tables and examples, and every bite-size is followed by an activity you check straight away. Key terms include Conservation of mass, Closed system, Relative atomic mass (Ar), Relative formula mass (Mr), Open system, Metal oxide, Mean, Range, Mole, Avogadro constant, Mole ratio and Reacting mass.
