- 01
Periodic Table and Atomic Structure
Development of the periodic table and atomic models, atomic structure, radioactivity, electronic configuration of atoms, and oxidation and reduction concepts.
- 02
Chemical Bonding
How atoms combine through ionic and covalent bonding, electronegativity, intermolecular forces, and the prediction of molecular shapes.
- 03
Stoichiometry, Formulas and Equations
States of matter and the gas laws, the mole concept, determining chemical formulas, and quantitative calculations from balanced chemical equations.
- 04
Volumetric Analysis
Expressing concentration of solutions, the theory of acids and bases, and carrying out titrations to determine unknown concentrations quantitatively.
- 05
Fuels and Heats of Reaction
Sources and structure of hydrocarbons including aliphatic and aromatic compounds, oil refining, exothermic and endothermic reactions, and heats of reaction.
- 06
Rates of Reaction
The factors that affect how fast chemical reactions proceed, including concentration, temperature, surface area and catalysts, and reaction-rate theory.
- 07
Organic Chemistry
Structure and bonding of carbon compounds, families of organic compounds, characteristic reactions and mechanisms, and key organic chemical reactions including polymerisation.
- 08
Chemical Equilibrium
Reversible reactions and dynamic equilibrium, the equilibrium constant, and how systems respond to changes in conditions (Le Chatelier's principle).
