Yeah strange, I think they will accept either acid or sulphuric acid(Original post by nisha.sri)
Yeh it is that's what it said in my text bookAlthough it said 'an....' so i think it's acid but i'm sure that's right

Yeah, I regret changing so many answers ffs!Like I changed fluorine to iodine, and in the titration I changed my answer so I said the acid was in the pipette
I think I got -1276 for that, and for the catalyst I put acidic
What did you put?
Meh, thank you - I really hope so tbh :/ I'm sure you did great because of how hard you have worked
I got 2 thousand somethingLol yeh that's right i put something very stupid
Those were the two annoying questions including the energy change one what did you do for that one ? -

I just write 'acid' since writing 'sulphuric acid' wouldn't have made gramatical sense.

What did everyone put for the Haber process question where you had to say why air shouldn't be allowed into the reactor?

I'm so confused.. Our paper didn't have a specific heat capacity question but we had most of the questions mentioned in this thread. 🤔 -

Idk I said that air contains oxygen which is reactive and so it will affect the reaction and ammonia will not be made?

wow i messed up the bond energy
i got 4722 for one side and 5998 for the other -

You probablyprobably did the further additional C3 paper . That's the one I did as well and I don't remember a specific heat capacity question. The papers are usually very similar but some questions are a bit different. -

for the speckfic heat capacity i gkt 55.10
i think i got 4.2*0.8*16.4 -

Yeh oh no !! I'm sure it won't mind
I got 2 thousand somethingLol yeh that's right i put something very stupid
Those were the two annoying questions including the energy change one what did you do for that one ?What did you put for the catalyst?
It was only 1 mark so it doesn't matter
For the energy changes one I just added up every single bond energy using the values in the table for one side and then did the same for the other side. Then, because breaking bonds is exothermic and making bonds is endothermic, I did the value on the right side of the equation - the value on the left -

I'm sure you'll still get 2/3 method marksWhat did you put for the catalyst?

that's exactly what i did also for one side did you get 5 thousand something?!
