For the bromine one I kept the same molecular formulae for the carbons and hydrogenated and added Br2

I got strong and weak as well, But I was unsure.
I got unreactive as well.
I wrote 53 seconds.

Dunno if they're right or wrong.



Yep 0.02.

C something H something Br something lol









What did you guys rearrange the formula to?

I done Delta T = Eh/(c*m)


I did some calculations before I rearranged it.

I multiplied c and M together
Then rearranged it so DeltaT = EH/cm

so basically the same as you but I did my multiplying first

Grade boundarie for a C last year was 48% and last years paper was Definetley easier than our one, so no doubt the grade boundaries will get lowered slightly

Yep

People found paper 2 more harder I think
There was a good few questions throughout paper 1 and 2 that I have never seen before, don't know why they do it
What did people get for the acid and base one? Was so confused

I don't want to start any arguments or anything but I feel that the SQA have been on a total rampage this year. Personally, I feel that all the papers they made for this year have been of higher difficulty to the previous one.

I agree.
It was towards the end and it was like identify the acid and identify the base and had a few tables

I think I got a weak acid and a strong base?

I might be totally making things up but for the Gold question with the passage you had to read.. The first part of the question wasn't even proper english grammar, The sentence physically did not make sense, but I understood what they meant nevertheless.
