Superficial is good. You don't want to peer beneath the skin of the dark science. I don't know if chemists are actually demons, or if they are just mortals who have made a pact with Satan.
Actually the two I know are neither. My brother-in-law is a Chemist and a teacher. One of the "Engineers" at work is a chemist. I don't exactly understand the difference. I asked him, "you're a 'Chemical Engineer' right?", and he responded, "no, I'm a Chemist".
I do know our "mole ratio" affects production substantially. The product I start with needs a mole ratio of (I can't remember if it's NaOH or Na2O, one is the dilute of the other) .70 to .80; Below .70 and the units run like crap. Over .80 and we make yellow product.
Regarding my yard. A mole ratio of .25 = destroyed yard. 1 mole, four dogs digging after the mole, trenches all over my yard.
