Solid copper can be produced by passing gaseous ammonia over solid copper (II) oxide at high temperatures. The other products of the reaction are nitrogen gas and water vapor. The balanced equation for this reaction is: 2NH3(g)+3CuO(s)->N2(g)+3Cu(s)+3H2O(g) What is the theoretical yield of solid copper that should form when 18.1 g of NH3 is reacted with 90.4 g of CuO? If only 45.3 g of copper is actually collected, what is the percent yield?
