The time that Father Murphy taught, they sure were some great years,
the difference between empirical and molecular formulas clear,
It helped a lot because of Father Murphy's disposition,
Converting between the formulae and percent composition.
That's how they showed their respect for Father Murphy,
That's how they showed their honour and their pride,
I never took another course with an emphasis on balance,
the reactants and the products with the numbers on the side.
His course is where I learned all about stoichiometry,
Limiting reagent, percentage yield, needed for chemistry,
There's only one problem I have, that I can really tell,
Stoichiometry is one word that I will never spell.
