habers process is done for commercial output of ammonia and there also comes a time for equilibruim in this reaction but the values r to get d highest yield of ammonia possible for commercial output.

Okay, I have a question.
May/June 2004, Paper 3, Question 4, (b)(ii)
Why the difference between the height of the precipitate between Iron (II) and Iron (III) salts?
jellybeans:
Questions! :D
i) how do you draw the structure of the polymer formed from but-2-ene?
ii) How do you deduce the formula of the alkene which has a relative molecular mass of 168?
is it something to do with the empirical formula of... idk CnH2n hence 3n = 168 ... blahblah
lol help please! THANKS.
