    This is probably a stupid question but....

    When you write out oxidation of alcohol equations and you have the oxidising agent as [O], does that O get included in balancing?
    I choose to balance it, but it's not necessary according to my chemistry teacher.

    Yeah, pretty much. Let's just hope they decide to toughen it up significantly and make it different, although realistically it'll just be another dumbed down piss take. :rolleyes:
    Why would you want a toughened paper?

    yep whenever ur short of oxygens on the left hand side add them to the [O], never change the number of moles of the other reactants.
    Cool thanks, I've always thought it makes sense to

    Why would you want a toughened paper?
    Because I'm not an idiot and would rather spend an hour and 45 minutes doing interesting questions rather than just recalling knowledge and doing the same questions that I've done hundreds of times already in class.

    Yes, I haven't really done anything for it yet. I did the energy as it linked in with revision for this but I need to do all the transition metals and buffers etc.
