Question

Ammonia gas can be prepared by the reaction CaO(s) + 2NH4Cl(s) – 2 NH (g) + H, O( g) + CaCl,(8) In an experiment, 31.8 g of ammonia gas, NH,, is produced when it was predicted that 42.1 g NH, would form. What is the theoretical yield of NH? theoretical yield: 42.1 What is the actual yield of NH,? actual yield: 32.9 What is the percent yield of NH,? percent yield: 0.781

Answer 1

Ca o (s) + 2NHU (8) + 2NH3 + H₂0 g) + lalu, actually produced amount at gas = 31.8g predicted amount of gas = 42.19. ie, Theoritical Yield of NH3 = 4.2019 actual yield of NH3 = 31.8g." we lc now, percent yield - Actual rield. - X100 Theoritical vield ^ %. 231. 89 x 100 42.19 - 0.7553X100 = 75053 % Actual uield of NH3=31.8g percent lield of WHz = 75.53%
