Yeah and its called a joke, they could choose something less stupid though. I used pyruvic acid and got a ratio of base: acid 14.5:1, anyone get this?

Did anyone get uses for H2 as hydrogen fuel cell vehicles and margarine production? Or does anyone know if they're right?

I put margerine production and ammonia production in the Haber process :smile:

I think fuel cells will be fine though since hydrogen is used in them :smile:

Exam seemed to go quite well but missed out the bit about the polymer and the bit about the recharhing of the cell??? Found that this exam was a bit of rush for time but that was probably cos I spent so long on the buffer question. Stupid magic tang.

The Pka Q, a low pKa means the acid the strong right? so acid in milk is stronger than vineger?? i got so confused here. Is that right?

Yeah, goodbye place.

Are you sure, i got 461 too?

I think it is 461 as some people forgot to cancel out the negatives. Either way, whoever is wrong will still have got marks for working :smile:

I just cried after an exam for the first time in my life. I needed 93 UMS for an A and I may not make that. I got something ridiculous like 2880 for Kc and my percentage of copper was more than 100% after spending 20 minutes doing the ionic equations I had no time to check.

Same ...actually believe it or not...i'm crying here just staring at the computer....93 is pretty low! You'll make it :smile:

If I do something wrong in the beginning of the question but carry on with it do I still ge follow through marks.
I though the rate question was second order but it was first.
