National Chemistry Week: Don't forget P-Chem


P-chem or "Physical Chemistry" for you pusses that steered clear, mainly educated me in humility. You can find all sorts of descriptions of what is generally covered in this class, but in summary it is a demonstration that everything that you learned in 100 level chemistry is sweet fantasy.
In P-chem you learn that an ideal gas as described by PV= nRT, is as fanciful as the ideal man in that they both exist only in theory. It's sort of like the life let-down that occurs when you find out that real-life romance is more accurately represented by "Fargo" than "Cinderella".
Instead of a tidy little formula involving solving for a few variables, plug & chug, mind the units, be all done, you have to start working with "real gasses", molecular collisions, and of course, the dreaded "entropy".

The math is trying, particularly when your class (of 8) gets combined with a graduate class of biophysics PhD students, all of whom were Chinese and proceeded to make us look like monkeys pounding on HPs in reverse Polish. In spite of their seeming superiority due to their mathematical skills, those Beijing boobs could not do experimental design to save their lives, so happily partnerships were made with a tad of mutual exchange which some may refer to as CHEATING, but hey, it's all about teamwork, right?

Fortunately, I survived but I'd rather birth a hedgehog than take that class again although I'm sure I'm a better person for it. Also apparently something about entropy caught my fancy, because I am now married to it. Damn.

the only chem I know is to not mix acid and chlorine. makes some sort of nasty cloud or somethin.

sulfuric acid + bleach = bad.
also bleach and ammonia. Its better to avoid cleaning products at all costs.

yeah, I'll just get a little non english speaking maid to do all my cleaning...'cause yeah, they know these things. lol

Easy peedee, just make sure you're not home when the magic happens!

A classmate at hillbilly high got an urge to wreak some havoc and decided to fill a squirt gun with a mixture of bleach and window cleaner, because we all know that is a combo which evolves chlorine gas which is quite toxic.
Anyway, instead of harming others he suffered injury, although not fatal. Apparently the Hand of God slapped away the hand of Darwin.

I've made that mistake...once! lol The hand of Darwin...nice. lmao
