Reaction equation
Reactants → Products. Stoichiometric coefficients balance atoms and charges.
Conservation of mass
Sum of reactant masses = sum of product masses (Lavoisier's law).
ICE table (advance table)
Table with initial, change, and final states. Advance x goes from 0 to xmax (limiting reagent depleted).
Limiting reagent
Reagent depleted first at x = xmax. To identify: compare n(A)/a and n(B)/b.
