    It's very synoptic. That's probably why

    Any chance of someone having a list of all the reactions with conditions we need to learn from memory for the exam?

    For elements of life (na)
    For developing fuels you are expected to do the following only: 'describe and design simple experiments to measure the energy transferred when reactions occur in solution or when flammable liquids burn; explain the limitations of such practical procedures'
    So reaction conditions are basically. Metal calorimeter with a known volume of water. Drought shields, clamped above a spirit burner which is lit. Stir and take temperature then put out spirit burner after a certain amount of time. Make sure to have weighed the mass of the spirit burner before and after the experiment. Use e =mc delta t to work out energy used using the mass of water (1G = 1CM3), specific heat capacity of water (given to you) change in temperature by measuring temperature before/after of water. Then, if you want kjmol-1 scale up by taking the energy transferred, the mass (known via weighing the spirit burner before and after) and the mr to work out moles (n = m/mr). e.g. 50000 joules of energy transferred via burning 0.24g of ethane (30) . 0.24/30 =8x10-3 moles. 50000 x 8x10-3 = 40 joules. 0.04 kjmol-1

    For polymer revolution (which is the main one):


    Addition polymerisation of alkenes: 200degrees c 1500 atmospheres trace of o2 catalyst

    Hydrogenation of alkenes: nickelcatalyst, 5 atm, 150degrees c (i, for some reason remember it as spikey 5)

    Hydration: phosphoric catalyst adsorbed to silica, 300degrees c, 60 atmospheres..

    for the electrophilic addition of bromine/ bromine water: room temperature pressure

    Hydrogen bromide: rtp strong hbr

    which is all i can think of atmmm

    To those saying this unit is short - it pretty much is. Partly because of synopsis and partly because the summer is usually when we'd be doing F336.

    How are you all feeling about this one? It's my last ever unit to learn and I've nearly finished it thank god.

    Hi guys, I was wondering if anyone could please list all of the assumptions we need to know for all of the acid/base calculations? Thank-you!

    Spleen I did a paper and managed to get a strong C; it was my first F335 past paper and under timed condition.... Hopefully it is going well, hopefully.

    I haven't done any timed practice papers yet but I intend to, soon D: eek.
    Does anybody know what the grade boundaries usually like?
    I sure am nervous about this paper. Ick.

    Can anyone explain how to do the neutralisation calculations between acids and bases please. E.g Question 4d part (v) on the Jan 2013 F335 paper. I can't find anything re. how to do it in chem ideas or anywhere else.
