One Last Key Point:

•The equation:

Hd + R + M + P + Co + Ct + 2 Hp + Cs + B ==> HdRMPCoCtHp₂CsB

is a recipe that tells HOW MANY.

It makes sense to say something like:
"1 Hot dog, plus 1 serving of relish, plus 1 serving of mustard, plus 1 pickle, plus 1 serving of chopped onion, plus 1 serving of chopped tomato, plus 2 hot peppers, plus 1 serving of celery salt, plus 1 bun makes 1 Chicago Hot Dog."



•The above equation DOES NOT tell HOW HEAVY.

It does not make sense to say:
"1 gram of hot dogs, plus 1 gram of relish, plus 1 gram of mustard, plus 1 gram of pickles, plus 1 gram of chopped onions, plus 1 gram of chopped tomatoes, plus 2 grams of hot peppers, plus 1 gram of celery salt, plus 1 gram of buns makes 1 gram of Chicago Hot Dogs."


Equations in chemistry only tell HOW MANY and not HOW HEAVY.
