same thing happened to me lol

I identified that it was a gp but couldn't knock the answer out. Will this obtain a mark?

for the calculation of purity, I wrote, the sample is 20% impure. Will this receive full marks?

exactly the point.

Lol, they both favour an increase in ammonia. I would upload if I could, don't have a scanner.

a and b both suddenly increase at time T. A goes slightly above and trends down asymptotically. B goes slightly below and trends up asymptotically.

yes but A and B both satisfy that.

I think I agree with this. It is B for nothing else other than the fact that A wouldn't make sense. B requires the least suspension of disbelief lol.

My reasoning was this: Part of Le Chatelier theory is that the system will attempt to counteract the change, but will never fully counteract it. Thus, I found it more likely that it will undershoot it, and thus approach it asymptotically, rather than overshoot it and come down to it.

I got B, maybe I'm wrong.

Oh sorry

I disagree. Humans have known for a long time that a fundamental difference exists between nitric acid and say citric acid. That is reflective of a primitive understanding of strong and weak acids that was later clarified by Arrhenius.

yeah? what is wrong with that? D is obvious isn't it?

it is extremely implicit in tests for "common ions." Unless you do not deem nitrates as common ions?

Not dodgy reasoning. The last 15 years of strong economic growth in Australia has most notably gone to the high income earners. Low income earners are less likely to have spare money to spend on investments and will thus not be able to take advantage of the large business profits that have...

I can also set the record straight for anyone who may be unsure about question 7. A major component of the NAIRU in Australia is disillusioned job searches, i.e. people who have stopped participating because they feel as though it is helpless. Now we can all accept that the unemployment rate...

yeah it can sometimes happen.

I agree with $200. I just think that BiasedBuffalo's reasoning was wrong.
