In the new practice depth paper (the one on the google drive link) question 5c where it asks you to identify the molecular formula of alkane X, I identified that the alkane has 7 carbon atoms in it so assumed its formula was C7H16 due to this being the general formula of alkanes. Yet the answer was C7H14, why is this?
We did that paper as a mock and I think my teacher said it is a mistake on the markscheme. By the way, where are these papers?
This is why the grade boundaries for this test have to be low, cause this is one of the only practise papers we can have for the exam and even the markers are getting confused on how to mark it.
Hey guys, just did a massive update to the OP. I think some people are missing some helpful links, resources and tips in the past few pages of the thread so I tried to compile them to make it easier and to make some resources more visible. Let me know if you guys want to add some to the OP or remove your post if you didn't want it in the OP.
I've tagged and added the username of the amazing posters (?) who added them to the thread so you'll know who to thank.
Users have added a lot of links to some such as compilation of past papers and access to that elusive second set of papers. Don't forget to send them thanks or however you guys thank people here in TSR (I think it was give them rep or something)
All the moles ones using masses n=m/Mr solutions n=cv gases n=V/24(000), PV=nRT and the the other adaptation of that formula in book The stuff for avogadros The dilution stuff (I can't remember for the life of me) Kc constant (products stuff)/(reactant stuff) I can't think of anything else right now

as im doing this again if i get a U or E will it be able for me to move to A2
If you get a U, probably not. Some teachers will allow those getting E's to pass through on a case by case basis. Revising is a better use of your time that worrying about your grades though
