Ok thanks, because my teacher penalised me once for missing the negative so i was confused

I thought delta h is always negative

Is it?

You reckon its possible for the paper to leak considering how the exam booklets are personalised? Ik it happened for bio

I also recall 1.9 for Pb, mustve messed up Cu

Hmm, yeah probs. Hopefully dont lose too many marks then

na dont think so, i got like -600 smth

What values did you get? Because i got ineffective for both

Same

Hopefully I can band 6 then haha

Oxidation and addition of sodium carbonate powder. Whichever bubbles contains aldehyde as it wouldve oxidised to a carboxyllic acid releasing co2

I don’t think they’ll mark with that much detail for a 3 marker so dw. What are your predictions on band 6 cut offs?

Did you say for MgCl2 it tends toward a crystal lattice structure but the release of heat during the exothermic process, it distorts and tends toward randomness through freely moving ions in a solution?

Ah that’s good. I hope so! I mean I got the calibration curves and everything for both Cu and Pb, hopefully I only lose 2 marks for that, not anymore. Man I hate silly mistakes 😩

Same. Did you say that MgF2 doesn’t dissolve?

Wait did you get effective for cu? I got 1.26 something for Cu...

Actually no, they provided us with data on delta H, delta S and T delta S, and Gibbs free energy. THEY already calculated everything for us, it was very weird

I am really happy with how it went! The two 7 markers were pretty much analytical and not theory based. One was where you had to plot the absorbance vs concentration for AAS and the other was a reaction pathway which was very fun. Not really many theory questions, a lot of calculations; not even...

Thanks mate, yeah gl everyone!

I meant that they’d give us the information about the processes and ask us to analyse them
