    how was chemistry paper 51

    Well, it's quite lengthy. But I think if you understand the stuff very well, then you will inshallah get at least 70 and if you got A in the rest of the papers, even the threshold mark, then Inshallah you will get A*. Actually, I calculated it and it was right. You can check it out too.

    How was Chemistry P5?

    Which variant you people are?

    how was chemistry paper 51

    By the way, even if someone think that he messed up , still P4 can boost the marks, since it is the backbone of A level chemistry.

    how was chemistry paper 51

    Well, q1 took more time than what I have planned. So I had to kinda rush in q2, did some silly mistakes. Overall, it wasn't that bad. It's just q1 was kind of shock when you see it, but if you read it carefully, it's actually a combination of some experiments in the past papers.

    Post Your AS LEVEL PHYSICS PAPER 2 DOUBTS

    listen, First u calculate S2M (Pythagoras) √(80²+100²)= 128 cm then path difference is 28.0 cm (128-100) Calculate lambda at 1.0 KHz which is (330/[1.0 x 10³]) = 0.330 m = 33 cm then claculate lambda at 4.0 KHz which is (330/[4.0 x 10³]) = 0.0825 m = 8.25 cm so lambda (wavelength) has decreased...

    chemistry practical 32 discussion

    for me, because the part was talking about thiosulfate ions, and how they reduce, so i thought about Fe3+ get reduced to Fe2+ by thiosulfate ions., donno whether rigtht or wrong. but it makes sense because the examiners said it in the same part, so obviously i have to use the fact that...

    Anyway, this is as far as i can approach...:confused:

    Chemistry 21

    it is right, but it is not the answer of question as far as i know, the answer is no effect on equilibrium yield of methanol
  15. V

    Chemistry 21

    temp is fine, normal answer, less methanol, catlyst no effect
  16. V

    Chemistry 21

    u r right, BUT & again the question asked the equilibrium yield of methanol, at when the equilibrium is re-established again after higher pressure, will the amount of methanol will be higher (after equilibrium is re-established)? of course not! because the temp. didn't change so Kp is same...

    Chemistry 21

    but at the end, the question asks equilibrium yield, which is at Kp, so it does not change!
  18. V

    Chemistry 21

    what u are saying is totally correct, the question asked about equilibrium yield they even made it bold in the exam ( never asked why?), Kp happens at equilibrium & and u know that change of pressure will give higher yield but the system is NOT at equilibrium. At equilibrium the yield is same if...

    I am really worried! Please help?

    dude, if ur marks are like that u will easily get B, because ur total is 165 & a B in Nov 2011 was out of 160 so Perfect ;)!!!!
