Chemistry is so much fun!

Molarity, percent yield, limiting reactants, acid-base reactions, redux reaction, ideal gas law, polarity - kill me please. All of this is basic stuff, but I don't really use it in my day-to-day work. It's tough to dredge my memory for all these ancient theories. Especially so late in the year. But it is good for me to exercise those rusty brain cells. Just a guaranteed headache after a long haul at the mill, though.
