Part of the Edexcel GCSE Combined Science curriculum.
Edexcel GCSE Combined Science Topic 4 Extracting Metals and Equilibria is a step-by-step online learn guide for GCSE students in Years 10 and 11, mapped to the Edexcel specification (Pearson Edexcel GCSE (9–1) Combined Science (1SC0) – Topic 4 Extracting metals and equilibria). It covers the reactivity series, displacement reactions and redox, ores and extraction with carbon, electrolysis and biological extraction, recycling and life-cycle assessment, reversible reactions and the Haber process and changing the position of equilibrium, 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 Reactivity series, Cation, Displacement, Oxidation (electrons), Ore, Oxidation (oxygen), Electrolysis, Cryolite, Recycling, Finite resource, Reversible reaction and Dynamic equilibrium.
