Units
All 6 units of Chemistry 30. Each one has a concepts page to learn from, practice questions marked as you go, and quizzes built at random.
Unit 1
Thermochemical changes
Energy released and absorbed by reactions: enthalpy, calorimetry, potential energy diagrams and Hess's law.
Unit 2
Oxidation and reduction
Electron transfer: oxidation numbers, half-reactions, balancing, and predicting whether a reaction happens at all.
Unit 3
Voltaic and electrolytic cells
Turning chemistry into electricity and back: anodes and cathodes, cell notation, cell voltage and electroplating.
Unit 4
Chemical changes of organic compounds
Carbon compounds: the families, IUPAC naming, the reactions they undergo, and polymers.
Unit 5
Chemical equilibrium
Reactions that go both ways: dynamic equilibrium, the equilibrium constant, ICE tables and Le Chatelier's principle.
