    re: HSC Chemistry Marathon Archive I'm actually really sorry! I misinterpreted :( Being so used to you hating on me I assumed it was negative/ you trying to tick me off. Please accept the PDF through PM as an apology. *need your e-mail...

    re: HSC Chemistry Marathon Archive I'm sorry, are you blind? Read what I wrote again m8. "Alter usual: Concentration 1 Molar Pressure 1 atmosphere Temperature 25°C = change EMF values." Therefore, if you cannot deduce from what I wrote: ALTER the conditions under which the standard...

    re: HSC Chemistry Marathon Archive See my post man, I got it right! :D Deswa said okay. Oh SLC hhhhaha. change temp/atmospheric pressure?Measured against standard hydrogen electrode blah blah... Alter usual: Concentration 1 Molar Pressure 1 atmosphere Temperature 25°C = change EMF values.

    re: HSC Chemistry Marathon Archive Ah I see :) Was freaking out because I wrote that on my test and we haven't gotten it back soooo *Sigh of relief*

    re: HSC Chemistry Marathon Archive My teacher said this as an explicit point (HSC marker) so i unno. (on that point we had to remove any signs of corrosion or oxidation on the metal's surface if it was something reactive like Fe or something...:( ) ... unless u are assuming the metals were...

    re: HSC Chemistry Marathon Archive - Oxidation/corrosion on the surface of the electrodes--> decreasing the EMF - Incorrectly calibrated laboratory equipment (voltmeter in this case)--> above/below theoretical values.

    re: HSC Chemistry Marathon Archive Edit: Adding to the above. Trend one: Bp rises with increasing molecular mass. The MM is increasing due to increasing Carbon chain length. In turn, the BP rises because of ^ dispersion forces- temporarily induced polarity within the non-poplar molecules...

    re: HSC Chemistry Marathon Archive ah that oxidation resistance thing i think. Au coated Fe nanoparticles are used in the biotechnology sect. Dunno how you would do it.

    re: HSC Chemistry Marathon Archive I found this one today. Thought it was pretty good as it draws on prelim content as well as HSC. Explain the trends in boiling points shown in the graph (4 marks) This is my rough answer from what I can think of now, but I would draw an example of each...

    The Problem with Rote Learning

    Rote learning, as Rivalry has said, would put rote learners at a disadvantage. At HSC level the education system is trying to cater for the learning abilities of all students. Rote learners are challenged in the science exams though, especially biology irrc. Bio is a rote-learned subject don't...

    Halp. Subjects.

    Did we? Lol. Did we decide on hist ext? I have no 2u subject to drop. :( bio chem adv, modern and art, keepers. it's the 1units :L Bro, did you do 3 majors?...

    Halp. Subjects.

    Yeah, as much as I loveee history it's probably going to get the boot. Definitely not. Visual arts is a lot more work than anything, think along the lines of chemistry. Makes little sense in terms of scaling but I guess it depends on the school and the medium opted to work in. I am doing 3...
