7. The equation below shows the reaction between magnesium nitride and water. 3 Mg(OH)2(0) + 2NH3(g) Mg3N?() + 6 H?O) ? a) What mass of magnesium nitride would you need to react with excess water to produce 25 grams of ammonia? [3 marks] b) What mass of water would be reasonable to use for this reaction? (Hint: think 10%) [3 marks] c) If this experiment was actually done using the masses of the two reactants that you calculated in parts a & b, and you only obtained 16.27g of ammonia, what would the percent yield be for your experiment? [1 mark] d) List and briefly describe two reasons why the actual yield of a chemical reaction this one is always less that the theoretical yield. (2 marks)
