Thats what i got =]Forbidden. said:For the blue colour due to the ferricyanide ion combining with the iron(II) ion I wrote: Fe(s) --> Fe2+ + 2e-
For the pink colour due to the phenolphthalein reacting with the hydroxide ion I wrote:
0.5O2(g) + H2O + 2e- --> 2OH-

this section was easy,
though i would of liked the 'role of scientist' question to be more than 4marks, as i knew so much about them =/
Fair test ^^
Damnit i spent soo much time studing the SS Xantho and Trottmans AnchorForbidden. said:Haha, I didn't listen to my Chemistry teacher that we should research two Australian maritime wrecks (was it?) and that point wasn't very significant in the exam.
I bet you got that from the Maquarie study guide, hooray for those who use textbooks/study guides rather than proper reliable research .mithril1337 said:Damnit i spent soo much time studing the SS Xantho and Trottmans Anchor
Lol's you got lucky
well you couldnt talk about the implications of their findings without talking about their findings first.mithril1337 said:Ummm
the question on early scientists wasn't focusing on theirachievments but more importantly the implications thereof ?
Just like the role of a chemist question, anyone who didn't research at all would say something like,Unwant3d said:well you couldnt talk about the implications of their findings without talking about their findings first.
Its like saying, yeah i won, but without sayin what i won.
As for the research two australian wrecks thing, yeah completely disregarded that
haha, has it been thoughrly asked?
don't worry i wasted several hours getting my restoration response just right haha.
well they would wouldnt they?Forbidden. said:In this year's exam I think they had more Shiprecks and Corrosion than Conservation.
They can come in different variants.Unwant3d said:well they would wouldnt they?
they asked like a full page on how you would restore 3 different types of metals last year, so they couldnt really ask it again. =/
In the HSC they will slip in variants of a certain topic that they know students (or should I say candidates) have struggled over for years.Unwant3d said:i know what you mean, i was dissappointed that "CFC's, Acid rain Estirification or the Haber Process" didnt get asked as a long response, as they are my best topics =/
How different metals must be developed to prevent corrosion over the years.k4t5UM0t0 said:What sort of things should I have written for the 6 mark question? It was so badly worded, I didn't know whether to write about the history of shipwrecks or not.
yeah i found that a little tricky to begin with but worked around it...k4t5UM0t0 said:What sort of things should I have written for the 6 mark question? It was so badly worded, I didn't know whether to write about the history of shipwrecks or not.
wat question was the haber process, i cant remember lol. abit of a blurForbidden. said:The Haber process made its way into our exam this year with only one question, if I got that wrong (like I did with the dilution equation).
