c. The limiting reactant has the lowest ratio of moles available/coefficient in the balanced equation.

a. False. The limiting reactant does not necessarily have the lowest coefficient. The limiting reactant is the reactant with the smallest number of moles relative to the reactant's coefficient compared to other reactants. b. False. The limiting reactant does not necessarily have the lowest number of moles. The limiting reactant is the reactant with the smallest number of moles relative to the reactant's coefficient compared to other reactants. For example, if the reaction only requires a small number of moles of a reactant, then the reactant is not necessarily limiting. c. True. The limiting reactant is the reactant with the smallest number of moles relative to the reactant's coefficient compared to other reactants. d. False. The limiting reactant would have the greatest ratio coefficient in the balanced equation/moles available.
