WebConclusion: I learned how to tell which one was the limiting reactant. In this case, the limiting reactant was K2CO3 because it was lower than the other reactant. The limiting reactant is the one that runs out first and by doing so it limits the amount of product that can form. We had to find the percent yield of CaCO3.
