    Yeh I understand but why would mass change the rate of reaction in the first place.
    I can't remember the question very well so I can't really remember the context. It wouldn't change the rate of reaction but it would change things in the experiment (I think) so it is a variable you would have to control.

    No worries... Will do - but be prepared to wait a lil while if thats ok! Where would you like me to put them? shall i send them seperatly to you both? or is there any particular plc?
    Send them however you find easiest. Thanks

    Can people explain to me why it was carbon 12 in the fill in gaps. I put isotope. I have never learnt anything in school about carbon 12 and it's not in the textbook so is this really the answer. I was pretty sure about isotope.

    Really?! Would you mind linking me to unofficial markscheme if there is one
    Okay, I cant find the pictures, but I saved them so ill try and upload

    I would love if you were right :P

    I have this too: I get stressed out because I can't remember what I wrote/ what the question was and it really confuses me afterwards!

    That sounds about right. Did you say about why e.g as it's an endothermic reaction which takes in energy? I don't know if you need that but I put it to be on the safe side.

    Well my first reaction to B2 was that it was very hard, so I was worried about how I had done. I think I did decently on B2, obviously can't remember what all the questions were but the main ones I am worried about are bile xD other than that it went quite well, poss lost stupid marks here and there and also those strange applied science questions e.g. why weren't Mendel's ideas accepted I think I only got 1 mark there. We shall see..

    Hoping B3 will bring my mark up, I found it a lot easier and could answer all the questions, again will have made mistakes in places, although I can't remember where, but I know I will have done!

    Chemistry as a whole went a lot better than Biology, I am just more confident in Chem as it's more mathsy and that's my thing. Thought C2 was really easy, silly mistakes here and there but on a whole think it went well. C3 I thought was moderate, some questions were challenging but I hope I answered them well. I know I have made mistakes- stupid ones- like mixing up sodium and lithium, put boiling point decreased instead of increased- that kind of thing but on a whole I was really happy with all the equilibrium questions!

    Only thing is I have a vague memory of some kind of why doesn't iron fit in this group or something to do with the periodic table near the beginning of C3, do you know what the answer was?

    How have you found Biology and Chemistry? Sorry for such a long reply! Trying to self-evaluate ahah
    I think I talked about the 'backward reaction', but I don't think I said it was endothermic.

    Other people have already answered your question on iron.

    I found Biology Unit 2 much easier than Biology Unit 3. I also found Chemistry Unit 2 much easier than Chemistry Unit 3!

    But then my own assessment of how I did isn't the most accurate because:

    1) I tend to overestimate the number of marks I get.
    2) I tend to believe that I did terribly based on a few difficult questions.

    P.S. I regret calling my username 'Palette'.

    lets hope that they accept just "acid"
    They will accept acid because it said what kind of chemical

    Msg for all the ppl who want the C2 paper,

    Ive done a new post, which ill link up to here in a min, the photos are loading ATM so when there all loaded u can all help yourselves
    I took them on my Nikon D3200 so when u all download them and open them, by zooming in you should be able to read them easily.
    Hope there ok, msg me if u want anymore or if they dont work an ill try to help.

    What did people get for the question where you had to balance the equation on c2?
    I put a 2 infront of the second substance - can't remember what that was now 😂

    Because the definition of Ar or relative atomic mass is the mass of an element in comparison to 1/12 of a carbon 12 atom ( C-12 was chosen as it is abundant and stable, but that was back in the 60s so you dont need to know that)
    So with the Ar you’re trying to know the mass of an element so 1/12 of C-12 is
    1amu atomic mass unit .

    Well you did say backward reaction, so hopefully you would get marks.

    That's sort of what you would expect, to find the unit 3s harder!! Chem unit 2 was really nice, loads on bonding which was great.

    I have the same problems tbh, I think the best thing is to forget about it all really... we can't change it anyway! But it's probably best to be pessimistic and be pleasantly surprised than be optimistic and disappointed.

    P.S. Are you artistic xD why did you choose Palette?

    What the hell was the C2 six marker, because i wrote about how endothermic the reaction is, but apparently it was about rate of reaction:confused:
