    What were the answers to the Multiple Choice Questions:

    1. About how many peaks 1,2 dichloroethane had - I wrote 3 but not sure.
    2. How many moles of Sodium Sulfate reacted - I wrote 1.00 mol but I'm pretty sure I'm wrong due to the wrong method I think I used.

    Also the question that asked to draw the structure of ClO7 - how many marks was that?

    Damn that was quite a hard exam!
    it was for one mark
    what was the section for the 1 mol in the MCQ a b c or d
    also what did you choose for the spectra

    I found the exam ok aswell. But there are many small things I'm unsure about in my answers.
    I wrote down the first 16 MCQ answers on my calculator before time ran out, this is what I got: BCACDDDDADBBDABB, didn't have time to write down the last 4.
    If you wrote down your MC aswell share them so I can compare

    It was D I think but not 100% sure, what did you write? And I wrote there were 3 peaks but again I'm not too sure.

    i wrote 3 too
    what was the answer for % uncertainty?
    and what was the compound represented by the mass spectra?
    Also, how was the reaction of iodobutane and the other compound( it included the ammnoia)

    I think it was 0.05/0.5 if I remember correctly (something with a 5 anyway). I think it was a ketone I wrote but not sure. And you mean the reaction with ammonia to produce an amine?

    I wrote it to be:

    2NH3 + 1-Iodobutane => Butylamine + NH4I

    So do you remember what you wrote for Sodium Sulfate moles? (It was part D I think of the MC)

    What did you write for the product of water with Cl2O7 .
    And in the mcq which gave a peak at m/e value 31
    It's HClO4.

    i wrote 1 i think its D
    and yes i did the same equation as you did
    but i wrote an aldehyde for the spectra not sure either.....

    I'm really not too sure to be honest, I tried to rush with the MC just because I knew the other questions I would take more time in. And what about the Stage 3 of the reaction with Barium Nitrate - what did you write for that solid? I wrote BaO but I've no idea. The last question was also a bit confusing - I wrote it's larger for Iodine and smaller for Titre, what about you?

    Molecular ion peak is 3.
    IR spectra produced belonged to propanone.
    Mass of Iodine 114.2g.
    Percentage Uncertainty: 1%
    Sodium Sulfate moles : 0.33 (not sure of the answer).
    Structure of Cl2O7 : Google it. Its on wikipedia.

    Paper was not that bad. What was the White solid produced at step 3? I wrote BaO.

    Actually I just realised it was 1% for the percentage uncertainty I wrote.

    i wrote the same BaO for stage 3
    for the last question, i i did no change for titre and a smaller change for iodine
    i used the first paragraph in the question were it said something about the unsaturation and iodine

    I got the same answers as you. For 0.33 I just guessed and crossed 0.33 because I ran out of time. But everything else we have the same

    yay!! i got the same for the molecular ion,mass of iodine,%uncertainty. cant remember the sodium sulfate one!
