    Conquering Chemistry-eutrophication

    xeriphic is technically right. The death of the waterway is a cause of eutrophication

    Ionisation of Acids

    Is it necessary to put the water in the equation?
  3. Paroissien

    Ionisation of Acids

    CH3COOH + H2O <---> CH3COO- + H3O+ H2SO4 + 2H2O ---> SO42- + 2H3O+ Acceptable?

    HELP!! can anyone explain the galvanic cell??

    Wow, a twitch! There is probably a down-side I can't see though
  5. Paroissien

    Propagation

    You don't actually have to name the stages. Just describe the overall process

    Battery Questions

    Bah! What do HSC markers know about the HSC!

    What biopolymer are you doing?

    Lactic acid is the monomer, not the enzyme. Lactic acid monomers link in condensation polymerisation (water eliminated) forming polyLACTIC ACID

    What biopolymer are you doing?

    All those properties are probably correct, and judging by the properties it could easily be used for food packaging. The bacteria is alcaligenes eutrophus though. I strongly urge you to call it that

    What biopolymer are you doing?

    I figured one current research would be enough, but thanks because it probably won't be And no speersy
  10. Paroissien

    hmm

    Glucose: C6H12O6

    production of materials

    Hahah, just go with it, you'll be fine. It is confirmed by text books
  12. Paroissien

    What biopolymer are you doing?

    Well that's the main point for all biopolymers

    The importance of structure

    Tables just seem wrong in an exam to me, but if thats what floats your boat, then don't let me stop you

    Battery Questions

    Any need to put the states of species in battery equations ie. (s) (aq)

    HELP!! can anyone explain the galvanic cell??

    I'd prefer a nutter who knew who stuff, to a stable person who knows less about chemistry than I do
  16. Paroissien

    HELP!! can anyone explain the galvanic cell??

    I don't bother with a mnemonic for that one. But I do like RED CAT and AN OX
  17. Paroissien

    production of materials

    lol. That's what I figured so I divorced myself from that equation
  18. Paroissien

    Battery Questions

    You are given plenty of time to do the exam, so there is no excuse to being less than perfectly legible
  19. Paroissien

    production of materials

    Yeah: Cathode: 2MnO2 + 2NH4+ + 2e- ----> Mn2O2 + NH3 + 2H2O
  20. Paroissien

    The importance of structure

    Whatever you do, don't actually put the dots in
