ohe, that is just great,,,,,, i fucking missed out the flame as well........ I am losing my faith for chemistry.

does it matter, like do you have to round it to a really accurate decimal, i mean as long as you show the working out...

i had something like 0.03mol per litre u guys?

yea, its like my trial when they asked what buffer is and i put the definition of a buffer solution. also for they asked for what corrosion, that got me cos i didnt exactly know how to phrase it

i know an amphiprotice substance is something that reacts with acid and base. but i put that for amphiprotic, are they the same ? also, is this equation correct cos that is what i wrote H2Po4- +H3O+ -> H3Po4 +h20 H2Po4 + Oh- -> HPO4-2 + h2o

you are, but i am just not what citric acid is for, i mean which part of the F_(*king syllabus was that in?

what did you guys write for acetic and citric acid? i put acitic acid is used in vinegar for food flavouring and citric in orange juice. man i am doomed aint I?

how so? if I had 100 in this test, my internal marks is gona get dragged up to 100, but the if second highest got 75. his or her marks will moved to 75, i dont see how my marks will affect others unless they achieve a mark above me.

is it okay if you put barium nitrate instead barium ion? for reagent. this test was tricky, hope its not the same for physics, cos i am counting on these 2 subjects

i dont think anybody will be beating me in my class and i got a shit mark and coming first with shit mark, so i am pretty much doomed.

I agree, its against those people who memorise notes from website. so aligning of marks got nothing to with UAI calculation? from that flowchart

I cant believe this, i told myself before the exam(REEEEEEEEEEEAD the bloody question) . worked the answer but didnt add it to the original temp, idiotttttttttttttttttttttttttttttt

final answer was A I put D cos i didnt realise the limiting reagen. i am doomed

far out, i knew i screwed this question cos i said it wasnt a really reliable test as soil particles can get in the way of the experiment(cant believe i said that), and i also said the average absorbance wasnt reliable cos 0.64 was far out, therefore the average absorbance is also incorrect...

thats exactly what i did, -----now which way do i put the battery in, think of the signs-----

from that chart of aligning, that means the higher your mark, less... its diminishing return..... wouldnt that be unfair for people who studied hard for this?

its tricky alright, god you dont know how pissed i am at this test.I thought i nailed the theory part and out it came so many pracs, i reckon people who did half as much chemistry as me would make up some believable bullshit throughout the exam and still beat me, lucky i rank first so i got some...

i am not good at this so, if anybody can tell me if i am wrong for q24 (b) first we work out the concentration of acetic acid. 4/100ml is 40/(litere) 40 g per 1 litre of vinegar. since molar mass of ethanoic acid is (60g) 40/60=2/3 mol per litre naoh+ch3cooh=Nach3coo+h2o ratio...

no where as much as english, you can study twice as much as the next person, and they can still beat you in the test......

for my, product. i mainly talked about how business should reach for youth market, bring out gadgety phones with mms and wap and shits like that to attract more youth. price- i put , u know market skimming and competitive pricing. promotion- i talked about advertising throu youth...
