can any plz tell me whats coming???

chemistry p33 9701 on the 12th of may!!

pleaseee

chemistry
hydrated ammonim salt titrated with KMnO4
usual salt analysis
one thermal question


this is taken from a post in anothr thread ..will post the details if i get them

Would we have to titrate ammonium nitrate with KMn04 or would we need to oxidize potassium iodide in the presence of ammonium nitrate and then titrate the resulting solution with sodium thiosulphate? :|

see question no.1 in june2008-31
a similar question is expected!

 

[junaidaftab]

is there any mention of sodium thiosulphate?

heyzz guyzzz plz sned me any information do send mee in pm plzzzzzzzz or esle mail em at [email protected] plzz m not so good at chemistry helppppp meeeeee.........

 

[hassam]

a level freak...ru sure its like m/j 08 31.....or is it like hydrated salt one like o/n 09 33

FOR PHYSICS ASLEVEL PAPER 33

what we hav been practicing is the electricity one with beads in place of resistors.its very simple..and ya in the oscillation one we will be having a cylinder instead of a pendulam bob..

i doubt anything concerning magnets or diodes on A2 level will come for As practicals, hmm, they might just be giving diode as just another component of the circuit system, in past years there were things like that, but the procedure is still the same, you will just have to either measure current, volt etc. and draw the graph, and by the way it will be helpful to review the graphs for diodes. before going for exam.

YOU WILL NEED
1.retort stand.
2.bob/cylinder
3.stopwatch.
4.thread
5.multimeters
6.batteries
7.clamps.
8.resistors.
9.contacts
