The limiting reactant in a reaction is [A] the reactant for which there is the most amount in grams [B] the reactant for which there is the least amount in grams [C] the reactant for which there is the fewest number of moles [D] the reactant which has the lowest coefficient in a balanced equation [E] none of these 11.Explanation: . When considering Limiting Reactant problems the most important aspect to consider is the molar ratio of the reactants. Here the balanced formula tells us that for every 2 moles of Ca there must be 1 mole of O 2 to create the product. The amounts given by the problem are the actual amounts we are given and can be compared to the molar ratio to determine the limiting reactant.Limiting And Extra Reactants Pogil Solutions Key Extension.
