So you will be crawling through piles of crap? Sounds fun :), can I join?

Self ionization of water? H20+H20 <--> H30+ + OH- Lol the only thing you could write about this is water's amphiprotic nature in terms of B-L definition of acids/bases, and conjugate acid/base pairs etc

^lol

Hi there, nice to meet you :)

Could you also say that it would be safe to use NaHCO^3 in excess?

Your assumption is correct :)

P.S. Do you really do 16 units?

Biochemical Oxygen Demand, I don't think there is any difference, however this is the terminology of the syllabus so it would be wise to use it. BOD is really the implicit measurement of organic matter present in a water system. You can measure it by measuring the initial dissolved oxygen (by...

Pretty much this

So what are you guys going to do if you receive a question based on this dotpoint (in CM&M) in the HSC?: • gather, process and present information on the features of the local town water supply in terms of: - catchment area - possible sources of contamination in this catchment -...

Consider your self unlucky, this is one of the perks in doing Industrial Chem :)

Despite the fact that I don't do Physics (however I do Chem), i'd say the former.

Couple of things: -Haemaglobin boosts the bloods oxygen carrying capacity by 100 times, as oxygen usually has very low solubility in the water of the blood plasma. -Haemaglobin consists of 4 haem groups, and thus is able to carry 4 molecules of oxygen for every haemaglobin molecule --> boosts...

You could have bumped up your old thread....

Realistically Aysce is right, idyllically you should have been in the top 5 for every one of your subjects, and the marks that you would need for a 95 in the HSC now may be too high, that being said imo your at 85/86, if you have smashed the external exams then it may be different.

imo 82/83 :), please do consider that Year 11 does not correlate to Year 12, things change, so remain consistent in your work and keep your head up high, with this attitude I could see you smashing that goal of 75 :)

Here was one from deswa1, it is an equilibrium constant question:

Post up questions for the Industrial Chemistry Option Topic for discussion :)

hhahaah yeah I was like barbernator u srs bro, I almost had a heart attack :)

Come on deswa1 quit the suspense :p
