so whaaat :P
-
Thanks 2 God I did very well :) I am satisfied. I hope paper 1 is the same
-
Done wid paper 22.. DAmn good paper..some questions seems way too tricky like the last question where we had to find black compound X..what was dat i couldn't figure it out. Organic was also gud. Seems thresholds will be high
-
Don't discuss the paper, the mods will kill you. =P
It was too easy. I know I answered the black compound one wrong but otherwise I think I did a perfecto paper.
-
Please don't disclose any details.
Chem :-* :P
-
Guys the paper was easier than most past pprz... but organic part was a bit tricky... i reckon i did fine... although last question puzzled me...
-
hey this chemistry paper 22, which one is this..? CIE, AS level?
-
hey, nice profile pic...is dat dhoni?
-
Isnt is Kurt Cobain??
-
hey, nice profile pic...is dat dhoni?
lol.
pretty sure its Kurt cobain. <3
paper was alriite. i actually did not get the first question. :(
-
Thanks 2 God I did very well :) I am satisfied. I hope paper 1 is the same
but isnt an 80 % an A , 48 out of 60 is 80% so i think that will be the A mark
Or not...?????
-
hey, nice profile pic...is dat dhoni?
lmao no its not dhoni..
yeap kurt cobain..from nirvana
-
the ppr was better than i expectd it to be
i bet all of us expectd it to b very hard
the only thing the threshold will b reeeeelllllliiiii very high
but lets hope for the best :)

is 24hours up yet???
-
YES!
Please discuss
What is the black solid?
-
YES!
Please discuss
What is the black solid?
It is carbon from reaction of H2SO4 and Propan-1-ol.

darn... :-\ i dont think i got that one.
what about the rest of that question... anyone remember?? something about why you remove it from water...???
oh. and why the thing turns black??

Nid404 said that it was CuO and she was quite sure about that!

Okay. =P Do you think it matters now? No one can change our answers now. Just work hard for P1 instead. =D
-
I also wote Copper oxide...

I didn't write that answer either. =/ I wrote that SiC reacts to form carbon, which is obviously not possible but at least I got carbon right. I'm not sure of the exact reaction/reactants/products myself.
-
hmm....i wrote that it was aluminium oxide which due to heat turned black. because they asked what was the substance x. u could easily see that it was a solid so i don't think it could have been H2SO4. and Al2O3 also helps to dehydrate alcohol to alkene. i read that some where. but i wasn't sure about that removing out of water thing......and guys for the last part of the last question the organic product should have been CH3COOH right?
