i dont know what diagrams u guys have...but in the one in our textbook the unreacted H2 and N2 are pumped back into the system to be reused again to make more ammonia.... to do that they probabbly use the different boilingpoints to them and ammonia..but yeh i assume that the unreacted H2 and N2...

yeh...we're doing it....and its kinda crappy! we have an assign atm on three different types of indigenous peoples and also contrasting all the stuff to do with them with ATSI peoples.....i find it soooo boring, but what can you do really!! its easy to crap on about in essays which is always good!

we did this prac today...n have to write it up for tomoz! we didnt actually use fertiliser, instead we used MgS04.....which we dissolved in HCL n then added BaCl...the aim was to add enough BaCl so that all the SO4 would be used up. We need to verify a simple test to verify this....im a bit...

horrible! our half yearly was worth 30%! it sucked! n a scary thing is walking ot of the exam thinkin it wasnt too bad..despite the fact that there was too much prelim n many questions i couldnt answer! n everyone thinking it was the hardest thinge ver! hopefully i passed that would b great! n...

in concordance with my other question.....i can find the properties i need for ethanol like its boiling point is 78 degrees and molecular weight of 46 and miscible in h2o and density being less than water...but all i can find for ethanoic acid is the boiling point of 118degrees and a molecular...

thanks thanks heaps! it was very helpful:D

we did a prac making ethyl ethanoate and i need to compare the physical properties of components of the mixture which allow separation by a) distillation and b) the use of a separating funnel....n im kinda confused as to what exactly i'm supposed to be writing...any help would be awesome please:D

im currently studying for my bio half yearly....n was wondering what the differnce was between cell mediated response and humoral response....i know that T-cells control the cell mediated response and B cells control the humoral response but what are they exactly

about ethanol at the moment there is no simple chemical way to decompose cellulose into its glucose constituents to be able to ferment it to ethanol! ethanol can be formed through the hydration of ethene which needs heat and a catalyst and is CH2=CH2 + H2O under dilute H2SO4 gives CH3-CH2-OH or...
