Couldn't find a forum for revised higher chemistry so here it is.

How did everyone find that exam then?

My mind went blank the first time I looked through the paper, but actually it was ok. There were quite alot of calculations, and I hope i did most of them right! Anyway, how did you find it??

Aw exact same here. A sense of dread engulfed me when I couldn't even answer the first q because I was so nervous. After thinking about it I think I did not too bad. Think I could've done a bit better on the 'using your own knowledge' qs but apart from that, fingers crossed!

I put distillation.

For one of my calculations I got £18

Another one for atom economy I got 87% I think.

For the liquid air I got 5somethibgsomtingsomethibg(big number) tonnes

They're the only ones I can remember!

Yay, I got the same! I think the liquid air one was 5.7x10^7tonnes.

I thought it was brutal.

19 on the multiple choice was wrong, the question didn't match the answers I worked out the volume for them all and 3 of them matched the volume of Sulphure dioxide. Crazy!

Yeah I got a b and c to = 2 the same as the question so I went for d=4 as it was the only different one

I got b, because a and c are diatomic
