First question: C. I think. lol Yeah i thought a nitrate precipitate wasn't possible.

A body of water turns into a swamp, and then into firm land, due to an excessive amount of nutrients such as nitrates and phosphates.

OH lol i had problems with that question as well. Thanks serge i didn't really understand why, coz i though max as in the maximum volume. But that sounds more logical.

Hmmm well it would be more accurate if you didn't round off. They wouldn't be cruel to take marks off because you are more accurate. I do not round, and I don't see why you should. Sorry I couldn't be of much more help.

1. Write the equation: 3H2 + N2 --> 2NH3 2. Find the number of moles of hydrogen (n = m/M) 3. Find the number of moles of nitrogen (molar ratio is 3:1) 4. Then find the mass of nitrogen (n=m/M --> m=nM) I think that is right :S

Was a bit suprised by the last question 7(b). I didn't know what it was going on about lol. They usually have projectile and binomial i thought for 7.

I thought it was quite hard actually. But those questions 6/7 mannnn they were shit lol. And i couldn't get some questions early in the paper which was pissing me off lol. I'm hoping that i at least get 60/84. I dunno because i do 4 unit am i meant to get higher lol :S..oh well no more maths...

hmm lemmi think: - probability *shivers* - binomial - circle geo - series/ financial maths *screams* ... actually i think the whole paper scares me...its maths lol...thats pretty scary

I am just hoping to pass that exam. I found the first few questions straight forward, but question 6 was an absolute killer, so was 7 and 8. Actually, after question 4 it totally went downhill....

Yes i have also felt quite intimidated by some of the results in here...they are excellent! My mark was a miserable 58/120 errrr! I re-did the paper with the answers next to me and realised it wasn't too bad...lol but then again, the answers were right next to me :P

hmmm i do not like Bush and that war at all :(

thank you very much.

I want to put 4 unit maths into the uai calculator and i don't know what i should put it. Just the 2 unit extension and 1 unit extension. sorry i'm so confused
