Consider the reaction that occurs when gaseous ammonia reacts with solid copper(ll)oxide: 2NH3(g) + 3Cu(s) –...
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?
Nitrogen gas can be prepared by passing gaseous ammonia over solid CuO at high temperatures. The other products of the reation are solid copper and water vapor. If a sample containing 18.1g of NH3 is reacted with 90.4g of CuO, which is the limiting reactant? How many grams of N2 will be formed? What is the theoretical yield ? If 6.63g are actually producted what is the percent yield in this case? I believe the balanced equation is: 2NH3(g) +...
