UNOFFICIAL MARKSCHEME ocr chemistry gateway today

for the conservation of mass question you just had to prove that the product had the same relative atomic mass as the subtance being decomposed right??? 168 and 168, therefore conservation of mass?

and for the addition polymerisation question DID YOU HAVE TO include the n??? ive heard that was just an add on or is it required???

first is pie
second is line

Yayyyy i battlled between bar and pie for first one i just guessed tbh

I put pie then bar chart & so did all my friends !?

I got E for the first question and F and C for the second one. And then C18 H8 for the third one I thinkk

Around 60 I think

i got C5H10 (alkene) because i assumed it was either the alkene or alkane (C5H12) so that they would add up to C10H22 because wasnt that the original? idk how other people did it

What do you think the main topics for Unit 2 will be?

I did predictions for this paper on my other thread it was pretty accurate

Ill do one for unit 2 soon

Im revisimg physics now

Oh cool same, I'm just going over P3!

How's everyone feeling for Physics?

Ok.. But ask me that after the exam and I may have a completely different answer I kind of want it to be a little hard so the grade boundaries are low but not too hard so I can't answer anything

I said that too!

Haha, not gonna lie it's the same for me But I think we can do this! Hopefully they'll go easy on us. I wish we could have low grade boundaries and an easier paper (yes I know that defeats the point, I'm jk) XD

I normally focus on the six markers first, then I move on to the other questions, when revising.
