but how does that make glycine superimposable :/


It has L and D enantomers so it can form mirror images of each other due to chiral carbons which are non superimposable

would it be possible to do retakes next year for F334 and F335?


yes Id assume so, but I cant afford to, second time Im doing it now already

same I got ABB for AS however need AAB with no resits so solely depending on A2 grades to bang. And I simply could not fathom doing a levels again this year has been ever so dry. Having said that, hoping I score
I havent done any past papers.
WOOHOO.
I'm ****ed.

But I deserve it.

I'm just currently watching videos and slowly creating more brain cells in the process ( Hopefully it's enough). Are you ready?

^^ How do you mean?

That was pretty hard :/

That was fairly easy.
Anyone get 97.something% for the Fe(ii)
chlorine gas for the toxic one?

That was terrible :/
But I got 97% and chlorine gas :biggrin:
97.1 for calculation question!
I put chlorine gas for the roasting one!
Lots of questions I just don't know whether I've got right!
I put V2O5 + 5Ca > V2 + 5CaO
I also put that the observations went from green solution to brown? Which I think is wrong apparently..
I know I did the Tri and bi question wrong because I read it wrong and also the ionic equation for the Fe2+ gah.
So many silly mistakes I think!!

Dayum guys, I found that a hard paper!

I got 97.1% too

I got VO^2+ as the ion that reacts with NaI
