Final answer:
The answer is d) Neither is limiting.
Step-by-step explanation:
The limiting reactant is the reactant that is completely consumed and determines the maximum amount of product that can be formed in a reaction. To determine the limiting reactant, we compare the moles of each reactant to their stoichiometric coefficients.
In this case, we have a higher percentage of K2C2O4·XH2O compared to CaCl2·2H2O. However, without the actual values of the percentages, it is not possible to determine which one is the limiting reactant. Therefore, the answer is d) Neither is limiting.
