    Chemistry:

    Paper 1 : What is a catalyst? (2)
    My answer: A substance that lowers the activation energy in a reaction by providing an alternative reaction pathway. It isn't itself used up in the reaction.
    Answer: It speeds up the reaction without being used.

    Paper 2 : What is catalyst (2)
    My answer: A substance that speeds up a reaction and isn't used in the reaction
    Answer:A substance that lowers the activation energy in a reaction by providing an alternative reaction pathway. It isn't itself used up in the reaction.

    Something similar happened to me with a definition, except the other way round: :/

    1st Paper: Define the standard enthalpy change of combustion.
    Me: The enthalpy change when one mole of a substance undergoes complete combustion at standard conditions.
    Markscheme: The enthalpy change when one mole of a substance undergoes complete combustion at standard conditions of 298K and 1atm pressure.

    2nd Paper: Define the standard enthalpy change of combustion.
    Me: The enthalpy change when one mole of a substance undergoes complete combustion at standard conditions of 298K and 1atm pressure.
    Markscheme: The enthalpy change when one mole of a substance undergoes complete combustion at standard conditions.

    Me: :shakecane:

    It must be so annoying when you're doing practicals and have to write down your observations.

    Got this from the "Official WJEC Chemistry unit 2 revision guide":

    "Polarization of an anion is when a polarisable anion is polarised"

    :rofl::rofl::rofl::rofl:

    My board is so stupid.
    :lol: We're just having a rant about Chemistry now. :teehee:

    We will be modelling in LA.

    Soz. :/

    Muahahah. And I have finished all my oboe grades - unless I do diploma. :rolleyes:
    Obviously.

    It's fine - you don't have to if you don't want to. :cute:

    Are you going to do diploma?

    :sexface:

    Okay.

    I don't know - I probably don't have time.

    I can't believe in the film of the hunger games, they left out the sleeping bag. It plays such a vital role! :shock:

    We do everything in pairs so no. If there is an EMPA I get an assistant. I'm lucky really, it's never caused any problems

    :hugs:

    That is a good point! :lol:

    :lol: Never mind the characters, it's the sleeping bag that should get a starring role. :teehee:

    On another note, my parents really liked my school report. They didn't even pick holes in it this time for the first time ever.
