1) How many grams of N2(g) can be made from 9.05 g of NH; reacting with 45.2 g CuO? 2 NH:(g) + 3 CuO(s) → N:(g) + 3 Cu(s) + 3 H,0() Based on your calculations how much N, will be made? Is this the theoretical yield or the actual yield? How do you know? If the reaction has a percentage yield of 80.6%, how much N2 will be made? Is this the theoretical yield or the actual yield? How do you know?
