[schwang_thang]

arghhhh i got 14 wrong
i was pretti sure the answer was (c), then at the last minute i changed it 2 (b)

whyyyyyyyyyyy!!!???

 

[spice girl]

woops, sorry, 7 should be B

a typo...

 

[mannnnndy]

I got the same 2. Hey what was with q13? Cause it seemed to me that none of them were right. Anyone else get that or am I the only one?

 

[Ozz^E]

Woo hoo...we all got 15!!

 

[big_arvo]

isnt 12 (c) coz it says on the grapph EMISSION REMAINING.. hence.. the more thats remaining, the less dats given off in the combustion...

 

[Bug]

12.
The graph is of % of Oxides remaning, the question is asking which is most effective at removing the oxides. If 10% remaing then 90% have been removed, this is more effiective then the one that removed 40% and left 60% behind.
Hence it's D.

13.
C - The NH3 is/was used to create explosives (industry), it could be used for farming as a source of nitrogen.

14/15, I'm happy.

Got Q3 wrong but that Q was hard (band 6 I would say ...)

 

[Nusrat]

Multiple choice sux big time.........1in4 chance......not even 1 in 2

 

[luigi]

1 A 2 B 3 C 4 A 5 B 6 C 7 B 8 A 9 D 10 D 11 B 12 D 13 C (?) 14 A 15 A


are my answers..

 

[luigi]

hmm i put 5b and 14 a.... DAMMIT

13 / 15 ... estimated 14 / 15 .. oh well

 

[-=«MÄLÅÇhïtÊ»=-]

dang
my memory told me that q8 was water water water. Coz i did sumfin similar to that ques b4. But den i realised after the exam that that ques was only refering to the conical flask.

and q12 seemed toooo easy to be D. I put down D, but i kept reading the ques over and over

 

[superhubert]

yep, 14/15, me happy clam
but err, why isn't 14 B? thats what i put.
All the big mark questions were the exact ones that i studied for, ie SO2 and NOx one, shipwrecks one, water treatment etc.
what was i so worried 'bout?
happy clam
hmmmm, me thinks the scaling on chem and phy will go down next year....
music aural turned out to be my hardest exam...
thats the one i thought would be easiest.
but who gives a #$%^? i'm a finished. i can put all this "knowledge in my 'pile of perpetual ignorage', get pissed, and forget 'bout it all for another 6 weeks or so when the UAI's come out....
FREEDOM WILLY, FREEDOM......

 

[-=«MÄLÅÇhïtÊ»=-]

why isn't 14 B?

coz temperature increase = speeding up reaction

 

[superhubert]

UM, IF THAT WERE TRUE, THEN WOULDN'T THE 400 LINE BE ABOVE THE OTHER?. (whoops, caps on) yield is different to rate of reaction.....i was told that hi temp decreased yield....

 

[Ronnie]

an increase in temperature speeds up the rate of reaction and decreases yield

hence it reached equilibrium faster at a point lower than 200 C

14 is C
