How is the limiting reagent determined in a reaction mixture?

• A. Use the greater amount of one reactant as limiting.
• B. Compare the mole ratio to the stoichiometric coefficients after converting all reactants to moles; the reagent that yields the least amount of product is limiting.
• C. The substance that dissolves least is limiting.
• D. Determine limiting reagent by the color change of the solution.
