Cyrus The Great

:s-smilie:

pbO2 u form cl2 gas aswell as its a more powerful reducing agent

Cyrus The Great

oh my bad it was out of 75

45/75 is 60%, which is a C.

60/75 is the minimum for A.

is it not out of 60? or is that just the AS Papers?

Cyrus The Great

no its 100% out of 75, 60 is for AS

come on questions ppl lol

does anyone remember what there Kc value was?

Yessss Thats Wt I Got Lol

that doubling the partial pressure question was a bit wierd, wt did u put?

something along the lines of doubling the partial pressure of H2 would have greater effect as it was p(h2)3

niceeee, i wrote the same but a bit mumbly, ii hope they accept

what does a catalyst have on the effect of the rate of attainment of the Eqm

jus checked june 2002 mark scheme as same questions about nacl and pcl5 /pcl came up, the mark scheme states the official answer as ph less than 1, im assuming this because of the dissociation of the h+ in the hcl and also it allows any answer from 0-3

Gah, I put 1-hydroxy-2-aminopropanoic acid. As did everyone else I've spoken to at college. Damn.

wats the value for L.E
and how do u do those esters ??
the amide and ester linkage

-2053 kj mol^-1 iirc :s-smilie:
