Question

For each of the following balanced reactions, suppose exactly 5.00 moles of each reactant are taken. Determine which reactant is limiting, and also determine what mass of the excess reagent will remain after the limiting reactant is consumed.

1. CaC2(s) + 2H2O(l) ® Ca(OH)2(s) + C2H2(g)
2. 3AgNO3(aq) + Al(s) ® 3Ag(s) + Al(NO3)3(aq)
