    Yep, it's perfectly safe to leave them out, imo. But if you're planning on tackling the latter questions they'd be nice to have. :)

    At this stage though youre safer to leave them out and fix your other mistakes in experiments and elsewhere

    It's a simple chapter. I would spend half an hour revising it. The experiments are just a little... ehh.

    "one of the half questions" which means you are still safe leaving it out

    Of course. Depending on what questions you are going to do. I have to answer one of the half questions and we don't do enviromental or industrial so...

    now to perfect my Experiments... I am way way behind aren't I? :/

    Well I have about 4 chapters done, so no, you're not way way behind :P

    CookieMonster, you always make me smile!! :D Let's hope we're in the same Med School!
    P.S someone in my school was pretending to be you!! :P hahaha.

    I did about four too: acids and bases, equilibrium, water and organic experiments :)

    Glad I can be of some assistance :p just remember, when you feel like you've nothing done, think of me and you'll feel so much better :P
    Haha that's a but weird, no? Well I'm flattered anyway :L
    I have some of the atom chapters, acids & bases and the organic reactions. Organic reactions took it out of me! :P

    I'm leaving out electrochemistry as we never did it and it just looks confusing to learn on your own. It probably isn't all that bad but nothing ever sticks as much as when it's drilled into you by your teacher, I find. Didn't do the option either so if electrochemistry comes up (looks likely tbf), q11 will be ruled out for me but sure 8/10 is still an OK choice I suppose. :P

    If you do biology you will be ok with the nitrogen cycle option and greenhouse gases. It's common sense. But I doubt it will come up this year

    To join the conversation about college Pharmacy in TCD is my first choice followed by Veterinary Medicine in Ucd.

    I haven't started Chemistry yet but it's my favourite subject so I'm just hoping it's a nice paper. Let's hope for a nice q3 because I plan on leaving out q2 unless it's ethene or ethyne (unlikely I know)

    Ethene seems to have come up loads...unlikely it will this year. You never know though, could see it in the organic reactions question. Have a look through the paper to see what I mean
    -might see you there then :)

    In Pharmacy? With some luck :)
    Yeah I know which is a shame cause I know it perfectly! I know what you mean, one year it came up in 10 or 11 wasn't it?

    23 pages in and there's still two days until the exam? Chemistry has some passionate students.

    I'm fairly screwed in that I've only revised chapters 2-4 so far but I'm only looking for a pass so I'll just quickly look over everything over the next few days and hope for the best.

    There's loads of people in my class just looking for a pass and I said just know the experiments and fuels and heats of reactions and that's 4/8 questions which if you know them really well is 50%. Then attempt q4 and q5 from memory.

    Thanks for the advice, I need to get into those experiments later today. I'm hoping for a rates and reactions experiment since those things are easy.

    There's still time to look over the whole course. At this stage, the most effective way of studying is to have the marking schemes of all papers in front of you (I have them all in a folder on my phone) and flick through the papers, verbally answer questions and if you're not sure on a few then check the scheme. You'll soon realize how repetitive the course is.

    Oh definitely! I'm not saying that there's not enough time. Just with the people in my class (not sure about anyone here) they just don't understand Chemistry! Even if they had marking schemes they aren't able to know what they're actually writing. One of them got 9% in the mock after spending 3 hours in the exam.
    So if you're in that situation focus on the chapters you understand! :)

    Stop go revise all experiments! first get them nailed then do organic chem, then oxidation-reduction, then acids and bases dont do the history of the atom wastemof time 1 q!

    Was it not ethene that came up last year? Can't see it coming up 2 years in a row

    Ah feck it, I have enough experiments to be studying I'll probably just leave it out. May spend 5 minutes at it to know the basics.

    If it comes up in another section they'll probably only ask you for a diagram or something, so know that. If you know the diagram, you pretty much know the experiment anyway, for ethene at least.

    If they bring up the ethene experiment in the organic question I imagine it'd be something like ethanol and ethene in a reaction scheme asking what reagent and conditions are needed to get from ethanol to ethene. Aluminium sulfate and heat! And that's all, hopefully. :)

    Do we have to learn all the equations from the experiment on equilibrium?

    I've seen them ask you to write them down in mock papers, but never in the real thing... Could be a good idea just to cover yourself, since equilibrium IS a lovely section

    Aluminium sulphate is a flocculating agent and is also used in tertiary sewage treatment for precipitating out phosphates.
    Aluminium oxide is what you were thinking of!

    I know I would love if a whole question came up on it :)
