    I found C2 okay! How about you guys? My B2 went really well so If this was my worst one it shouldnt matter; we still have physics

    i think i left out the balancing equations , because i didnt know it was there.
    what was the question? , was it lead bromide?

    You don't actually know who I am.



    Anyway

    Did you do this?

    30+25= 55 cm^3

    End temperature- initial temperature= overall temperature (energy) change in the experiment so 32-18= 14 C.

    Specific heat capacity of water: 4.2 J/g/C

    4.2*5.5*14= 3234 J?

    yeah! , since it said OVERALL temperature

    I did. I think I got one out of five marks for that question, two if the examiner's generous.
    Yeah that was a harsh question, not expecting much from it

    Not sure about the exact question but all you had to is put a 2 infront of the second compund

    be honest, for the ions question will i lose marks for saying iodine instead of iodide?

    I think I did well in C2 (with the partial exception of the 6 marker) but C3 should have relatively low grade boundaries.

    I hope there are enough future McDonald's employees who get Fs, Gs, and Us to pull the boundaries down.

    It reminds me a bit of dynamic equilibrium.

    No, for the testing ions section in C3

    The maximum temperature was 38 degrees, 32 was the bit where you had to work out what it should have been but that wasn't the maximum temperature it reached, so the temperature change was 20 degrees

    I put that the units were J or you could have put kJ

    Nah the 3's always tend to have higher grade boundaries because it's normally only the people who are good at science who choose triple science
