LIST OF CHEMISTRY LABELLED DIAGRAMS REQUIRED FOR HIGHER SCHOOL CERTIFICATE

Pupils are expected to draw and label these repeatedly, until they can memorise them:

  1. The behaviour of beams of protons, neutrons and electrons in an electric field.
  2. The shape of an s orbital.
  3. The shapes of px, py and pz orbitals.
  4. The dative covalent bond that leads to the formation of the aluminium chloride dimer.
  5. The shapes and bond angles in the carbon dioxide, water, boron trifluoride, ammonia, methane, phosphorus pentafluoride and sulfur hexafluoride molecules.
  6. The Born-Haber cycle for sodium chloride.
  7. Reaction-pathway diagrams for exothermic reactions.
  8. Reaction-pathway diagrams for endothermic reactions.
  9. Diagram to show the partition of a solute between two solvents.
  10. Boltzmann distribution for reactant particles, including the effect of raising the temperature of the reaction mixture.
  11. Energy profile diagram to compare an uncatalysed reaction to a catalysed one.
  12. Boltzmann distribution curve to compare an uncatalysed reaction to a catalysed one.
  13. Concentration-time graph for zero-order reactions.
  14. Concentration-time graph for first-order reactions, showing the meaning of the term half-life.
  15. The lock and key model to describe the action of an enzyme.
