Re: Chem Lab C
I think you would be able to determine this based on what was given. All you need are the beakers, water, and the soda cans..correct?Skink wrote:I don't think so...both are the same except for sugar vs. aspartame. Both solutes should be relatively nonacidic, so I'm guessing the only observable difference between them is the following, though I'm not sure if you could determine this based on what was given...

I'm pretty sure, according to the wonderful chalker, that it is reduction/oxidation and periodicity.manutd94 wrote:So, what is the topic for chem lab looking like for next year (2011-2012 season)?

Re: Chem Lab C
Periodicity. Yay.
I should be better at this now that I've gone through AP Chem. At regionals, we accidentally found the electron potential by doing E(anode)-E(cathode) instead of the other way around. The rest of the test was easy, and that probably brought us down to 11th from a medal.
Oh well. Should be fun next year.

Re: Chem Lab C
I am sooooooo mad about this test. We literally finished the test before we began the second lab portion, because it was so short and easy. We checked our answers afterwards, probably 5 times, but we didn't see one little tiny mistake we made.
What did we end up with? 28th! With like a half point worth of mistake... This test was probably the second easiest test I had in this year.....
What did you guys think about it? Does anybody know how they broke the ties?

Re: Chem Lab C
I'd guess that they graded the tests really harshly. You had to show every single step they were expecting to be written down, or else you would not get the points. I think we lost points on the density lab. It seemed so simple; I think we did not show enough work.
When it comes to the future, there are three kinds of people: those who let it happen, those who make it happen, and those who wonder what happened.

Re: Chem Lab C
Yeah, we got 27th with a very good test. I can't specifically remember any tiebreakers, but I do remember going through the test and finding few, if any mistakes. The problem was that it was not only east but also very short; there must have been no stratification between "good" and "mediocre" whatsoever.Tidus wrote:I am sooooooo mad about this test.

We might also have lost points because of your terrible handwriting. But really, how much work can you show for density? Mass, volume... divide. We even wrote the formula down. But I do think the test was too easy for nationals; they may have encountered the problem of one point being a five-place difference or something similar. Maybe they got a lot of people on adding acid to water or sig figs or some tiny detail.Paradox21 wrote:I'd guess that they graded the tests really harshly.
