Question

The equation representing the reaction used for the commercial preparation of hydrogen cyanide is: 2 CH_4 + 3 O_2 + 2 NH_3 rightarrow 2 HCN + 6 H_2O Based on this equation, which of the following statements are incorrect? Rewrite the correct statements to make them correct. Three mol of O_2 are required for 2 mol of ammonia. Twelve mol of hydrogen cyanide are produced for every 16 mol of O_2 that react. The mol ratio between water and methane is 6:2. When 12 mol of hydrogen cyanide are produced, 4 mol of water will be formed. When 10 mol of methane, 10 mol of O_2 and 10 mol of ammonia are mixed and reacted, O_2 is the limiting reactant.

Explanation / Answer
