Ammonia can be produced from the following reaction: CaO (s) + 2NH4Cl (s) = 2NH3 (g) + H2O (l) + CaCl2 (s) If the expected percent yield were 25%, how many grams of CaO would be needed to react with excess ammonium chloride to produce 1.00g of ammonia? 1.00 g is the (theoretical or actual?) yield of ammonia. What is the theoretical yield of ammonia necessary to produce 1.00 g of ammonia?
