Year 10 chemistry
Every topic for the year is below, arranged by the term it is taught. Choose a term to show only that term: each topic has a lesson video, worked questions and practice at three levels.
Autumn term
- ChemistryQuantitative chemistryConservation of mass, relative formula mass, the mole and Avogadro’s constant, reacting masses from balanced equations, limiting reactants, percentage yield, atom economy, and concentration in g per dm3 and mol per dm3.100 questionsLesson video
- ChemistryStructure and propertiesStates of matter and state symbols, ionic compounds, simple molecules, giant covalent structures and metals, how structure explains properties, and diamond, graphite, graphene, fullerenes and nanoparticles.100 questionsLesson video
- ChemistryTransition metalsHow transition metals differ from Group 1 metals in melting point, density, strength, hardness and reactivity, with examples from chromium, manganese, iron, cobalt, nickel and copper, and their typical properties of ions with different charges, coloured compounds and use as catalysts.100 questionsLesson video
Spring term
- ChemistryRates of reactionMeasuring rates from graphs, collision theory, the effects of temperature, concentration, pressure, surface area and catalysts, activation energy, and reversible reactions and equilibrium.100 questionsLesson video
- ChemistryElectrolysisElectrolysis of molten ionic compounds and aqueous solutions, predicting the products at each electrode, half equations, extracting aluminium, and the electrolysis of brine.100 questionsLesson video
