Cameroon GCE O-Level Chemistry study plan

Define the mole and convert confidently between mass, moles, molar volume of gases at s.t.p. and number of particles

Write and balance full and ionic equations for at least fifteen reactions, including combustion, neutralisation and precipitation

Apply the kinetic theory to explain diffusion, Brownian motion, changes of state and the effect of temperature and pressure on gas volume

Calculate empirical and molecular formulae and percentage composition from given masses or percentages

Solve reacting-mass and gas-volume problems using mole ratios without looking at a worked example

Distinguish strong and weak acids and bases, and write equations for their reactions with metals, carbonates, oxides and alkalis

Explain the pH scale, indicators and the difference between strong and concentrated

Perform titration calculations from titre, concentration and mole ratio, including dilution and back-titration style problems

Describe the preparation of soluble and insoluble salts by the correct route, naming the reagents and separation steps

Interpret solubility rules to predict whether a precipitate forms

Deduce electron configurations and relate them to group and period position for elements up to calcium

Define isotopes and calculate relative atomic mass from isotopic abundances

Explain the trends in group and period properties, including reactivity of alkali metals and halogens

Draw dot-and-cross diagrams for ionic and covalent compounds and describe metallic bonding

Relate structure and bonding to melting point, conductivity and solubility for named substances

Classify reactions as exothermic or endothermic and draw energy-level diagrams with activation energy and enthalpy change labelled

Explain how concentration, temperature, surface area, pressure and catalysts affect rate, using collision theory

Describe reversible reactions and predict the effect of changing conditions on equilibrium position

Assign oxidation numbers and identify oxidation and reduction in given equations

Describe electrolysis of named molten and aqueous electrolytes, predicting electrode products

Describe the extraction of iron and of aluminium, including the chemistry of each reduction step

Explain the reactivity series and use it to predict reactions of metals with water, acids and displacement

Describe the properties and reactions of oxygen, hydrogen, chlorine, nitrogen and sulphur compounds

Explain corrosion and the methods of rust prevention, including sacrificial protection

Apply electroplating and electrolytic refining to unfamiliar industrial contexts

Name and draw the first six members of the alkanes, alkenes and alcohols, and write their structural formulae

Describe cracking, polymerisation, fermentation and esterification with equations and conditions

Distinguish saturated from unsaturated compounds using bromine water and describe the test in full

Compare the properties and uses of a named fuel and relate combustion products to environmental effects

Describe the chemistry of carbon dioxide, carbonates and the tests for the gases met in the syllabus

State the tests for cations and anions using sodium hydroxide, ammonia, flame tests, dilute acid and barium chloride

Plan a qualitative analysis scheme for an unknown salt and justify the order of tests

List the safety rules for heating, handling acids and alkalis, and disposing of waste, and apply them to described scenarios

Describe the correct use of burette, pipette, thermometer and balance, and identify common procedural errors

Interpret a results table and suggest improvements to an experimental method

Complete two full timed past-paper style papers and mark them strictly against a mark scheme

Redo every question missed previously across all ten domains and explain the correct method aloud or in writing

Memorise the key definitions and equations that repeatedly appear, and recall them in a five-minute self-test

Practise showing working and units so that method marks are not lost
