alright thanks mate. so i can do it either sem1 or sem2? just making sure because it kinda screws my (preferred) timetable this sem but i dont want to kick myself out of advanced math by not doing a mandatory course lol.

hey just confirming. is SCIF mandatory for commerce/advanced math? like do i absolutely have to do this degree at some point? i know math1151, econ etc are needed for the commerce component. cheers.

i think the question just asked for magnitude of force on AB so you didn't need to put a direction

ok i looked my paper, i agree with all this. now to get off this forum and go and enjoy my life!

however, when the magnet leaves the magnetic field, there will be another change in mag flux, therefore an induced emf, but it will be in opposite direction (because magnetic field lines are being removed). nt: i dont even have the paper with me atm so idk even if that is the question you...

really straightforward exam. what an amazing way to finish HSC! FREEEDOM! :)

as ive said in every other cutoff thread, imo it will be around the same. why? difficulty is entirely subjective. aside from something completely new and random like mod B for advanced (which fucked a lot of people up) whether someone finds a test harder/easier could really just come down to...

yeah i got around 9.9g or sth for galvanic around 0.31 for citric acid concentration (or maybe 3.1? but that seems a bit high, i dont remember really except my answer had 3's and 1's in it) dont remember my answer for the second part of galvanic (concentration of nickel), think i may have...

also i think i got 0.31 (or thereabouts) for the citric acid one. (cant remember actually, but i remember 3's and 1's in there, and 3.1 does seem a bit high) mentioning le chatelier's principle for the 6 marker (or any equilibrium question really) is probably necessary for full marks...

if you didn't know, you can ask for extra booklets. (that said, a few times i did just write under the lines a little because i didn't really want to get a new booklet for like 1 sentence :/) i'm pretty sure from what i've read on the forums that its ok to go over though

^yes if you apply V=n/c with arbitrary numbers you can confirm

was hoping for 95+ but dont think i can get it. anyone have idea what state rank cutoff might be this year? :L

for neutralisation i said energy required in bond breaking is less tahn energy needed in bond formation thus always exo. (i think this was what we learned in prelim for why things are exo/endo) meh idk.

didn't really go as well as i would have liked :( anyone reckon they can guess a state rank cutoff this year? i probs have no chance but... :L

also i agree with all of khorne's answers

question 12 was D (DECREASING order - most reactive one first. the ones with negative reduction potential are stronger - see data sheet) 15 is A (i dont think it has anything to do with strength, its all V=n/c, 2010 hsc q7 had a similar question)

^ i suppose but i guarantee that most HSC candidates would probably not even attempt that. HSC really isnt going to get much harder than that lol

number of moles of HNO3 = conc*volume = 0.03*0.1 = 0.003 similary number of moles Ba(OH)2 = 0.001 now 2HNO3 + Ba(OH)2 ---> Ba(NO3)2 + 2H2O mole ratio of barium hydroxide to nitric acid is 1:2 so for 0.001 moles of barium hydroxide, 0.002 moles of nitric acid will react. so there are...

^ i got the same :L holy shit that is a monster of a question though. haha guess the chance of that popping up in HSC is extremely low though

i have two more exams left and im feeling drained. except you probably can't call it drained in my case, because im just a lazy fucker. LOL
