any of these could all come up as they weren't in paper 1

1. Atomic structure (protons, neutrons, electrons etc.)

2. Dot-and-cross diagrams and bonding

3. Structure (as it relates to bonding) – difference in properties of simple and giant covalent structures

4. Redox – definition in terms of electron gain/loss not covered, perhaps one to expect with electrolysis?

5. Periodic table – group 7 not covered much

6. Iron and rusting

7. Organic – very little on alkenes, alcohols can only come up on Paper 2, molecular structures of these and particularly polymer structures

8. Pollution – nothing on acid rain, e.g. SO2* and NO2

9. Qualitative analysis – there was one short question that covered tests for K+, NH4+, Cl-, CO32- and SO42-. Some scope for another question?

10. Moles – nothing so far on gas volumes or calculations involving the faraday. Question on titrations was unusual so a more orthodox question is not unlikely.

11. Industrial electrolysis

12. Energetics – energy level diagrams and calculation of enthalpy changes from bond energies

13. Equilibria – nothing examined on Paper 1, so worth revisiting basic ideas and learning the industrial processes for making ammonia and sulfuric acid.
