yes did you?danz90 said:For people doing industrial, did you determine that the system was NOT at equilibrium?

no it wasn't... i think Q was less than Kdanz90 said:For people doing industrial, did you determine that the system was NOT at equilibrium?
That's what I said. Everyone kept telling me the potassium got reduced somehow.JamesTockuss said:The cathode was the chlorine gas turning into chlorine anions.
Yep.danz90 said:For people doing industrial, did you determine that the system was NOT at equilibrium?
i did that too and got 1.6mg zinc.... does any1 no how to get the answer?squeenie said:For AAS, you were supposed to work it out from the graph, right?
I think its the other way around:danz90 said:Awesome, got this too
And the equation was :
Ni(s) + 2Cl-(aq) ----> Ni2+(aq) + Cl2(g)
?
Sweet i got that. And yeah i said it wasnt, because k was out be a d.p or something is that what you got?danz90 said:Awesome, got this too
And the equation was :
Ni(s) + 2Cl-(aq) ----> Ni2+(aq) + Cl2(g)
?
NitrogenOSMANAYD said:yeh i got the exact same results. What a relief.
What did everyone get for the 4th mc question? Was it water or nitrogen that is most abundant in the atmosphere at the ground state?
I agree, there was too many calculations compared to past years.hjp. said:they overdid the calculations this year.
which blows.
meh, its over.
No you have to calculate it. although i think i got 1.7mg but i did some sort of calculation cant remember what it was now.r0kstar said:i did that too and got 1.6mg zinc.... does any1 no how to get the answer?
because the concentration was 1.6mg/Lr0kstar said:i did that too and got 1.6mg zinc.... does any1 no how to get the answer?
I rather liked that question.JamesTockuss said:All very good except for that Ethanol being carbon neutral question - although talked to my teacher afterwards and amongt the waffle I answered it!
But yeh heaaaaps of calculations!
I dont think so - I think the KCl was just the electrolyte? Because Cl2 gas was bubbling it - they wouldnt have it doing that for nothing -_-Aaron.Judd said:That's what I said. Everyone kept telling me the potassium got reduced somehow.
My contribution for: YAY!independantz said:Yep.
Yes, I got Hydogen. That was one of the easiest calculation questions in the paper.squeenie said:It was an alright paper. Not too easy, but not as hard as some of the past papers I've done.
Did anyone else get hydrogen gas for question 20?
I second that. Although i got 0.165mg/tablet, Graph must of been slightly different.danz90 said:because the concentration was 1.6mg/L
And the sample was 100mL, you had to multiply 1.6 by 0.100L to get 0.16mg
hey dude i got that too.... u sure its rite?fishbulb said:Uh no.
Ni(s) + Cl2(g) ----> Ni2+(aq) + 2Cl-(aq)
The previous one has two oxidations, which is impossible
I didn't really mind the industrial chem option. Other options were certainly harder. I screwed the equilibrium constant one in industrial chem so had to go back and fix it up after I realized what a stupid mistake I made in forgettign to find the cocnentration from the given table!!!gcchick said:Friggin awesome exam. The calculations were a bit iffy, and the Industrial Chemistry option was a bit of a bitch. But overall, pretty good. Sayoonara Board of Studies!
yep positive, i do shipwrecksr0kstar said:hey dude i got that too.... u sure its rite?
