So how was the exam? I did alright luylz
-
i thought it was pretty easy, but writing the equations for the NiCd fuel cell, screwed me over.
What did people get over the efficiency of the fuel cell over the combustion of hydrogen, near the last question?
Im not that great at chemistry but heres my multiplechoice
CCAC
DCAD
BACA
DCAD
BDDC
anyone else ?
-
cmon u faggot viewers, post something.
= (
-
Alright I think the questions where okay.. I finished with 2 mins to spare. but overall I think it was harder than mid year and way longer to much reading and thinking specially for multi choice.
-
it was ok except for the .9V question on the fuel cell
-
for the .92 v question u hatta figure out q using n(e-) X 96500....and then q = it....E = VIt ....so E = q X 0.92

good to hear! :)
Well done to everyone, Enjoy your FREEDOM [or soon to be for some people]
solutions coming right up.... after a nap.
-
yeah i assumed n[e-] was 2, because of the equation and i did wat u did,
-
MAO U SEXY BOY.. WOOT WOOT.
-
Isn't i remember getting like 2 x 96500 for Q and that E = V x Q... and transposing.
hard exam.. probs lost heaps in MC... extended response probs lost heaps of little ones... wat was the Ni Cadmium half cell equation... was it just simple redox balancing?? :(
-

I'm the opposite, i thought it was much easier then the midyear

same maybe because i picked up chem this year, and gay ass stoichemetry took awhile to sink in.

did anyone got 25.34 degrees celcius for the final temperature of the 2nd question?
-
pretty easy i think..
i finished it 20mins before.
save some marks from checking...( * last ques didnt see the word 'half'..--so stupid)
And i guessed one question ..."
the recharging equation for NioH2.( cannot be bothered to figure out)
-

nope =(
-
did anyone got 25.34 degrees celcius for the final temperature of the 2nd question?
25.34 is impossible..( u heat up water just by 0.34 degrees?)
* i got 25.3+ 44.45( cannot remember the exactly value, but it was something like that!) = 69.8? ( around there)
-
What is everyone's ans for the reasoning of a lower amount of methanol?
well..i guessd it..( saying it was due to the poison of the catalytic electrode)...
hummm...brain stucked..cant think of any good reason
-
i said something about non standard conditions
-
I thought it was much easier than the midyear, so hopefully i'll get an A
-
It was ok. Was pretty angry that we had to write an equation for our chosen chemical (H2SO4) since my teacher told me not to learn those equations. I tried to write the Lead acid battery equation, but I'm not sure if I wrote the right states. I think I got quite a few MC wrong and the Ni/Cd and 0.9V questions.. Did anyone get a blank paper to scan/put up solutions?
-

You forgot to convert kJ to J, 69.8° is correct
-
i think it was alright, pretty easy. just yeah a lot of reading it was long as. is someone going to post the questions and answers?
-
Has any1 written up the answers for chem exam 2? :)
-

I'm pretty sure thats what i got, from memory. :)

haha mine are so different. i just guessed but. eh, exactly how good would you rate yourself in chem on a scale of 1 to 10? :P
-

I am writing some up :P
-

I got the same, you had to convert the kj to j, find the increase then add it to the initial temperature!!
I thought it was very easy considering I did minimal study, but hey I might've just gotten everything wrong :P I was happy walking out though :) Should get around a B/B+...A if I'm lucky :)
For the concentration question in short answer using KA (i've forgotten the chemical, ethanol or something) did you guys end up with 0.35M? :)
-
bucket ..huhu
yeah.Same here
-
my multi choice was
c b a d d a a a b a c a a d d d c a d c
but i didnt get a chance to check over any of that so who knows if its right
-
i put down just 44.5 it asked for how much it increased by. not total did it?
-

WAT THE FUCK SO DIFFERENT FROM MINE, OH DEAR :(
-

Nah total
-
it was ok except for the .9V question on the fuel cell
ne = It/F
ne x V = V i T / F
E / F = Ne V
E = Ne V F
i cant believe i subbed 1 for number of moles of electrons.. o well ... 1 mark.
-
I wrote methanol evaporates so theres less of it after electrolysis.
-
Very fair exam :D

wat was the exam out of?

nope =(
yes:)

it's wrong. can't be done.

Yes. I did. I think its wrong clearly though. :(
-
What are consequential marks? Can someone give me a definition?
If I didn't know the answer to part a of a question, but needed it to calculate part b, and if I said
"If x = 49328492"
then used that to calculate the answer using the correct method, would I get marks?
-
pretty easy i think..
i finished it 20mins before.
save some marks from checking...( * last ques didnt see the word 'half'..--so stupid)
And i guessed one question ..."
the recharging equation for NioH2.( cannot be bothered to figure out)
OMG IT DID SAY HALF DIDNT IT
FUK
-
2 of my friends full marked it and my gf lost 2 marks :( argh.
-
cmon u faggot viewers, post something.
= (
i agree, that's with every thread!
-
garh... i thought i aced it but i think i lsot atleast 8 marks probably 10.. atleast
thar goes a+
-
hey what would 89% on sacs, a mid-high A+ for midyear, and a high A to low A+ (depending on where the cut off mark is) make in terms of a study score
thanks

that's what happens when you are competing with people like mao and dcc

That's almost exactly identical to my results...
-
what abouttt 98% on sacs 72/78 in midyear like 76/78 in this one??
-
43+
-
what abouttt 98% on sacs 72/78 in midyear like 76/78 in this one??
ohoh that's like me =)
i thought it was a fairly easy exam too. forgot to memorise the sulfuric acid equation thing (its use or whatever) so at least one mark off, meh

lauzy358 who's your uni chem teacher?
-

i got that for my midyear and wanted a similar score for end of year but had a shocking day probs get 65/79
what would a low A and mid A+ get with 94% sacs

umm dwyer? i'm @ monash. he teaches at some school, i always forget the name...
-
omg, that guy is the best!!! i went to one of his lectures and he was so comprehensive and enthusiastic about every bit of chemistry he taught! i think he also released his own study guide...
-
ahaha yeh, i can see that =P
he was pretty alright, we used to take breaks in between lectures and watch about 10 minute's worth of funnies =]
i still got pretty sleepy in the lecture theatre though lolol
-
Just to clarify - is the multiple choice mark going to be doubled like it was in the midyear? That threw me off some in June and I'd rather be prepared for it if it were to happen again. Thanks!

Everything is doubled.

everything is doubled? whats that mean

I was listening to one of his enhancement lectures on muso and it seems like a really fun class.
-

If max exam mark is like 40, then it'd be doubled to 80.
So if you got 30/40 in total, you'd get 60/80.
Ratio's the same, doesn't change anything.

gee lauzy i wonder who you are...cos i got to the funnies filled uni chem class too! =P i THINK i know u=D haha...have fun on monday with me!
