    Thanks so much for reminding! I looooooove chemistry. :love:
    No problem! I love chemistry too I've only actually discovered this in the past few months so have been working my way through some of the 2012 ones. It's crazy how on the honours board people have managed to do it in like 20 minutes!!! :eek:

    Yeah me too! I had been planning on doing Chemistry at uni for like the whole of last year and no teacher at school had mentioned it to me. Came across it like 2 months ago and had a go at the June one. Was kinda tough!

    You'll have to keep me up to date on how you're doing! We'll see who wins

    I didn't decide on chemistry until like May this year! Whereabouts have you applied to? and yeah, I'm surprised it never got mentioned at all at school! I did the June one a few weeks ago... it was hard but not hard as the may one that I did today! I liked the "how much graphene would be needed to cover the surface of the Earth" question... thought it was pretty cool

    And yes! I'll probs be on this thread while I attempt it!

    So are you in year 12?

    Oxford, Warwick (got an offer from them today!), Durham, UCL and Imperial what you applying to?

    I couldn't get past arranging the elements into the 50 year discovery thing! Arghh

    Nah, year 13. I applied to cambridge, durham, imperial, UCL and bristol. And haha, that question was annoying! It took me ages to sort them out! :lol:

    I ripped up cards and tried doing it like that. Still no luck!

    Oooh what course?! Shoulda applied Oxford! ;p

    Oh great. I love these challenges! Days of staying up until midnight back last spring still resonate fondly with myself ^^"

    Guess I'll be doing that on Wednesday night then~

    If you try and figure out which two have to be in the middle it makes it a bit easier. I applied for natural sciences at cambridge, and I'll hopefully specialise in chemistry. I applied there because I really like certain topics in biology too, so I'd be able to do them in the first few years too. Was hard choosing between cambridge and oxford though!

    Ooh good luck! I'm sure you'll have no problem

    You could do your PhD at Oxford!!

    So they choose to start it on the night after Hallowe'en. At least they're only taking the top 5 scores! D: I'll have to start next month.. :/

    AHHH, stuck on the gold question, I got the surface area of the earth in m^2 as 5.1*10^14, the mass per m^2 of graphene is 7.4x10^-7, so it follows that the mass required to cover the earth is 5.1x10^14*7.4x10^37?
    And the asnwer is incorrect o.O

    Why 10^37? :confused:

    Plus, for the surface area of the Earth I used the figure 510,072,000km2

    Maybe your rounding will have caused an issue. I can't remember what figure I used for the mass of graphene per m2 though.

    PS: You do realise this is the June 2012 challenge, not the November one, right?

    Woops, I meant 10^-7, and it still gives me the wrong answer >.>, yeah just realised that this isn't the November one :P

    Look up a picture of the krebs cycle on google images, find the right molecule in it and count the number of atoms of each element in in to give you the molecular formula.

    Thanks, just realised that I didn't remember the question and have been NAMING IT instead of writing the molecular formula... oops.. now feeling stupid considering I'd found the molecule and was getting really confused........................ /awkward THANKS
