    HAHA, i wrote about protons and electrons for the 2nd first question so im more fed than u
    I didn't really know what to put so I just wrote about emulsifiers and the hydrophobic... Hopefully I can get a few marks from writing what I did

    For the question about improving apparatus was it ok to say about using a lid for an insulator to prevent heat loss escaping?

    Yep. Wrote basically the same stuff. Emulsifiers, hydrophillic and hydrophobic molecules attach to the water and oil moluecules to harden the substance. We NEEDED to put the catalyst of nickel and heat of 60oC.

    I'd be very surprised if we get points for emulsifying and hydro's.

    Well it's over now so no point in worrying about it, nothing can change but good luck in your other exams

    Is it alright if I wrote that the neon atom was wrong because the first she'll should have 2 electrons, and that its group 0 so should not have one electron in the final she'll it's she'll should be full? I think i wrote somethings else but I can't remember
    Also I wrote that insulating the cup would improve accuracy because there's less energy transfer so temp doesn't go down ? Is this right?

    Would i get a mark if I wrote: protons and neutrons, negative and positive charge, +1 charge and -1 charge for the sub=atmoic? not even 1 mark?

    1 mark for saying that it is protons and neutrons

    Genuinely think i've got about 30/60... what a shocking result. Might even have less than that! If I get a C i will literally cry.

    I said that it did not reach a high enough temperature to thermally decompose therefore no carbon dioxide was being released which is why the limewater did not turn cloudy.
    Exactly what I put 😂😂

    I think i put:2Fe2O3 + 3C ---> 2Fe2 + 3CO2
    Is this not right ??

    No it should be:
    2Fe2O3 + 3C ----> 4Fe + 3CO2

    Unfortunately not.Well, I don't know 100% as this part "2Fe2" should just be 4Fe

    iron is a metal so it won't be 2Fe2 (no covalent bond)it would be 4Fe

    Ah well. It's done now let's just hope the grade boundaries aren't sky high. It will probably be similar to last years

    Which I don't know whether people like that or not.

    I certainly don't... I'd hope a* was more mid 40's... that gives me a shed of hope to get an A at the most...
