prospects for paper 2 chemistry pearson edexcelWatch
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.
