# Find the balance reaction and set up and use Before-Change-After (BCA) tables. Concept Introduction: For the given unbalanced equations, the number of moles of each reactant is given. The equation needs to be balanced and the number of moles of the reactants needs to be compared to find the limiting reactant. The moles of the excess reactant that remains after the limiting reactant is completely consumed can then be determined from which the mass of the excess reactant can be calculated. Finally by comparing the moles of the limiting reactant with the number of moles of each product, the number of moles of the product formed after complete reaction can be determined and then the mass of each product can be calculated.
