Hi guys! these are the topics that are most likely to come up in paper 2 : BTW THIS EXAM IS ON THE 13TH
Ionic crystals - 3 dimensions
Draw diamond + graphite - properties explanatin
electrolysis- (aq solutions), half equations
electrolysis calculations- faradays
Group 1 and 7 reactiveness- outer electrons and nucleus etc
Ethanol- ethene manufacture, fermentation,Dehydration of ethanol, positives and negatives of each method
Energetics- calculate enthalpy(heat) change and calculate bond energies
Contact process
reactions with alkenes and alkanes- addition and substitution
tests for gases and water
Titrations- method, indicators and moles and concentration calculations
Energy transfer diagrams
extracting aluminium(electrolysis) and iron(blast furnace)-uses
Cracking hydrocarbons
Polymers- addition and substitution,uses
The Haber process- reversible reactions , how temperature and pressure affect yield of backwards and fowards reactions
oxygen reactions - e.g. hydrogen peroxide
water of crystallisation
decomposition of carbon dioxide
covalent bonding

Here are all the topics that might come up in in paper 2 guys :smile:
