    who cares.. just know that in the syllabus, systematic name means IUPAC name. common name means common name.

    "Describe the action of sulfate reducing bacteria around deep wrecks"

    sulfate reducing bacteria - do as their names say... they reduce sulfates at the bottom of the ocean to form sulfides etc and in doing so, encourage the oxidation of iron or the metal of the ship hull. so, basically even though there isn't much/any oxygen at such depths, to be reduced, the...

    Le Clanche cell, help????

    no. the leclanche cell is the dry cell....:p try something else. perhaps one given in the syllabus - vanadium redox, lithium battery, mercury button cell...

    Amphiprotic or Amphoteric

    unless there are acid/base reactions that AREN'T neutralisation reactions, i disagree with what u have said.

    Quick Q - Sulphate reducing bacteria

    what do u mean by 'still'? when did we doubt its importance in this topic of sulfate-reducing bacteria :p i thought the centre of discussoin was about whether to put/not put the oxidation of Fe(OH)2 to Fe2O3.H2O as pointed out in the first post in this thread

    citric acid is 2-hydroxypropane - 1,2,3 - tricarboxylic... it does matter where u put the OH

    umm so whats the precise distinction between conservation and restoration again? *sigh*

    Quick Q - Sulphate reducing bacteria

    ok i think i have an answer for ur question. NO. you dont write that oxidation bit because the whole point of this focus is we're discussing anaerobic conditions, hence there wouldnt be the oxidation of fe(OH)2 to Fe2O3 or whatever. :D

    shipwrecks...rate of corrosion

    lol, due to increase in mass of oxygen... oooooh ummm, one question related to this: to what extent do we need to know the results of pracs in chemistry (and even physics), especially shipwrecks, where there are soooo many experiments... huh, huh? i mean like the different values of masses...

    is that a raw mark?? :eek:

    90+ for chemistry

    huh? whats the relevance of acmilan's raw marks? what was his raw and aligned mark for biology/sciences?

    Australian Maritime Projects

    u know how the dotpoint is compare conservation and restoration techniques applied in ur two blablabla... so how would we compare realli? i am having trouble. e.g. what if ur two project things are completely different, and were conserved and restored using different methods, how would we...

    Quick Q - Sulphate reducing bacteria

    ok, for that sulphate reducing bacteria dotpoint, i think u only need to know: how iron is oxidised what is reduced along with the oxidation of iron the products formed arent that relevant or necessary, in any case. don't worry about it too much.

    reliability and validity

    omg.... are these ur own notes or? u mentioned from BOS? straight from the horse's mouth? they seem pretty valid to me :D thanks!!!

    Need for collaboration

    chemists, like all scientists, need to collaborate, because often processes in real-life chemistry require the knowledge and expertise of more than just a single scientist or a single branch. hence collaboration needed.

    I Know Whats In The Hsc Exam!!

    well the refluxing apparatus doesn't actually speed up the reaction. but it allows the reaction to occur to completion. true

    I Know Whats In The Hsc Exam!!

    yes u are correct. refluxing allows the reaction to occur at a higher temperature than would be possible normally, as the volatile reactants arent lost...and hence can reach activation energy... but the fact remains that most books talk about a double-barrelled reason for using acid in...
