Isn't the molecular formula for Propene in question 3.3, 'C2H6' (i.e. General Formula for Alkenes: CnH2n)? It has been written instead as C3H8, so the equation balancing may actually be incorrect?
Hi, what would you approximate to be the grade boundaries for this paper? Or relative to your class' results on this test, what did you set the minimum mark for an A? Thanks in advance :)
for question 2.2 my gradient ended up being 2 x 10^-6 so when i divided the rates by each other I got 2.285 and then rounded it up to 2.23 and when I did 1.5^2 I got 2.25. I then rounded them both to 2s.f. and went on to say something like 'when conc. increases by 1.5times rate increases by a factor of 2.3 to 2s.f. 1.5 squared is 2.3 to 2s.f. so the order is 2' would I still get the marks in an exam?
Idk if you see the comments anymore, but just wanted to check: when asked to draw the structure of a molecule, do you have to draw out every bond like a displayed formula?
idk if i’m being rlly stupid but question 8.1 (48:47) why is it 2-deoxyribose?, is it because of where it’s attached?, can you just put deoxyribose? cause i do biology as well so i would’ve just put that😅😅
It's given in the data sheet and since all you have to do is copy it, they want you to copy it exactly 😅 you know how exacting chemistry is when it comes to names lol
@@TruthPrevailsAlways-1 Nah the point of x4 is to get the 1.25 not having any decimals, could do by 8 but sometimes they want empirical which is simplest form.
