Edexcel Chemistry

Anyone know what is likely to come up in Paper 2 for CHEM IGCSE's?

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.
