    That was a difficult question... I only got it in the last minute or so, before that i was just staring at it blankly. It was essentially a reacting masses question, except, you kinda had to do it backwards...

    Step1: find number of moles (urea)
    n=m/Mr
    =6000/60
    =100

    Step2: use ratio 1:2 (2 ammonia molecules for every one urea molecule)
    100x2=200

    Step3: find mass of ammonia
    m=nMr
    =200x17
    =3400g

    Phew.

    Found it ok , but for the paper chemical thing , I wrote the people in support of it may need large amounts of paper : . Would that be right ?

    Ahh no don't say that :p:
    Lol, hopefully not, but most found it easy so there is a high chance.

    I would say it was easier, was pretty relaxed. All the Chemistry past papers seemed easy to me, compared with Physics and Biology.

    This paper was easy as it was mostly knowledge, no trick questions.

    I got 3399 i think for the second to last question about Urea whereas you all seem to have got 3400, hope i don't lose all the marks for it =[

    If your working out was fine , you'll probably get the marks

    I got 3400g and then 76.9% for my last two answers as well
    I found this easy, and there wasn't really anything on (in)soluble salts which I'm glad about as I missed all of those lessons so it's not really my best!

    I've thought all of the Chem papers have been easy (today's and past) but I think this might have been the easiest, though whether my mark will reflect that..

    It certainly went a lot better than Biology. Only Physics left now.

    I found it so much easier than past papers that I did. Much of it did not test my knowledge though, and they may increase the grade boundaries, which im pretty disapointed about. I would rather have a slightly harder paper with the same grade boundaries as last year.

    If they raise the grade boundaries, i'm gonna be extremely disapointed. I got the 2nd last question wrong so thats 3 marks down the drain. I MUST GET AN A*... I've tried so hard!!

    The 'heavy water' question, with the hydrogen isotopes was quite difficult too. I can imagine there are some tricky marks for that question... Does hydrogen usually have one proton and no neutrons? and the isotope has one of each? I dont know...

    Confident. I also believe the grade boundaries will be notably higher. As my one of my friends quite aptly put, "But we'd been revising the hard stuff! None of that came up!" Sums it up quite well, I thought. Sometimes it is the easier questions that are the hardest.

    Also, for the the Urea question:
    (2)Ammonia : Urea
    34:60
    (34/60) * 6000 = 3400

    Or you could see that 6000 grams of Urea are made from a ratio that is 34:60. The Urea goes up by x100, therefore the Ammonia would too go up by x100.

    Hey,

    i did that exam today and i too found it extremely easy!! for the last two questions i also got 3400 and 76.9%. The only question i slipped up on was how nanoparticles were conductors (or something along those lines) as i didn't cover it in class! x

    do remember there are the ret**ded corner shop hoodies which spell chemistry like 'kemistree' doing the test, so grade boundaries should stay constant :P

    PHEW! I was worried about the answers for the last two questions but as with many on here, I had 3400g and 76.9%. I was very skeptical about that question :O

    But yeah, I have the same worries that the grade boundaries will be highered because although I don't want to say that it was an easy paper, it certainly was not as hard as the past papers we've been doing.
    Everybody came out of the exam saying that it was "EEEEEEAASY"...
    Was pretty surprised there was no empirical formula stuff...

    Hehehhehhehehehhee :yep: me too. Was disappointed at the same time 'cause I do like empirical formulae too...

    Didn't like the hydrogen-1/hydrogen-2 question And my mind went really blank on the copper kettle question... I think I only obtained a couple of marks at most out of the 4

    Same, the copper question panicked haha, and thank god nothing came up about pH because I missed it in school (well I don't tihnk it came up..)

    For the hydrogen question did you write a 2 on the top and 1 on the bottom? I got sketched out and for some reason thought about writing a 3 on the top haha
