I'm doing it, haha! Means that I get twice as much out of studying chem.

That's awesome! I am too.
I have a question with equilibrium.
The formula for the equilibrium constant seems so arbitrary (concentrations raised to coefficients). Why does it work?
Do I need to learn physical chemistry to understand this.

The law of mass action expression was empirically determined - there's no theory behind it, it just works

Okay. So it's just something I have to accept then.

Okay. I have been killing myself trying to search for an explanation.
I found a paper of the ACS website that tries to explain it, but you have to pay for it

The rules state
Each student must bring safety equipment and a writing implement and may bring a non-programmable, non-graphing calculator, and one 8.5" by 11" two sided page of notes containing information in any form from any source.
Could this mean that a team of two could use two pages of notes?

Yup. Same change in forensics this year. If it's anything like that, you won't know what to do with the extra space...

It's been like that for some time now. However, I'd have a rule sheet handy with your bag or something in case the supervisor didn't pick up on that!

For Chem Lab, are we expected to study and have knowledge of Organic chemistry (the reactions and stuff)
