Should be all good for tomoz. Hopefully they dont pull out some of those questions where u need padantic wording.
2 discussion questions for each option, that will suck but its good if u know it!

OK, if we are to believe that this is the case (dot-points not asked as of yet will be asked tomorrow) have questions ever been asked multiple times in previous HSC's? E.g. was a question that was asked in 2001 asked again in 2003?
I think if this isn't the case, then we can safely say that we'll get the remainder of the dot-points. Unfortunately, I do believe that this is the case...and such, we could be asked anything...just as always.
If anything, doing a bit of added research of this unanswered points has proved to be pretty effective...these are some points I haven't covered as much as some others.

No, I'm making it up to doom your HSC.nosadness said:
The resulting mixture after fermentation is only 15% ethanol (or 14 - 15 as Lace said.) Hence the need for distillation afterwards.
EDIT: By 'stuff' I'll assume you mean the reactants (that is, the remaining glucose and stuff that's left over from fermentation. Taking this definition of 'stuff,' I'm basing this on common sense, but I would say no. The yeast would be effectively dead at this stage and the loss of carbon dioxide and ethanol produced would mean only a very, very, very small amount of glucose would be remaining. It would be much more effective to just start over if you're going to make more ethanol, since extracting anything useful from the resulting solution aside from ethanol would be long-winded and unneccessary.

if its any higher, the yeast will die.taxman said:No, I'm making it up to doom your HSC.
