WHY is there MORE THAN 40 people voting C AND D ???? IT'S DEFINATELY NOT C OR D... YOU DON'T OMIT THE VALUE...

Well... considering most ppl can't even get pass 50% for HSC trial Chemistry... (biased judgement based on my low class average) it's pretty hard to get 65% lol....

I vote B cos i reasoned with myself that the question asked for the average (and i remember somewhere in Year 10 science... that you're not suppose to take out any result in the calculation even if it's 1000 times different from the rest of the result) and the more decimal places the more...

Wasn't there 1 on fermentation ? :S Anyway all the sections in the core that i hope wasn't in the test was in the test... Core: didn't want titration, presence of cations Industrial: didn't want solvay and saponifcation and wish came true

I agree. But the exam is still hard... cuz too much to remember.

Well if that's the case... one more mark gone... off my already 20 marks gone.... ... OMG... i hope i get at least 7 for MC... ****

I dunno... when i was doing that question i visualise my textbook and i recall that the lower the temperature the better the yield..... (im not going to touch that conquering chemistry textbook ever again...! it was more like Chemistry conquering me.)

Your working out confuses me... i dunno how a minus sign got in there... and H20 is 17 amu, NOT 18...

(quote)Would someone be able to explain the working behind question 6, sorry.(/quote) Well... i think the glucose monomer for cellulose has 5 O atoms, 10 H and 6 C.. so simply you just add them all up 16x5 + 10x1 + 6x12 (which is the weight for 1 monomer) and multiply it by 5 (since there are...

i am sad because it's sooo hard.... especially the titration thing no clues... I thought chemistry was suppose to be easier than physics... and physics was easy (cuz there wasn't any stupid experiments question)... can't believe this chem exam is sooo hard.... :( :(

Thanks... but i think a website would be more efficient. Um... did you woke up on the wrong side of the bed today? I do apologize if my questions conjured an image of the typical stressed-out person that IRRITATED your malfunctioned cerebellum so much, that you feel the need to post a false...

Hi everyone.. ok my first question is.. where can i get PHYSICS PRACTICAL EXPERIMENT RESULTS on the net because 80% of the experiments that involved magnets don't work (because the school can't afford new ones) and others I can't even understand. I know you're supposed to tell the truth but...
