Ammonia is produced on an industrial scale by the reaction of nitrogen gas with hydrogen gas (the Haber process). Ammonia is used as a fertilizer, as a refrigerant gas, for purification of water supplies, and as a household cleaner. Exposure to the corrosive gas can result in necrosis of tissues in the nose, throat, and respiratory tract. The Haber process proceeds according to this balanced equation:
N2(g) + 3H2(g) → 2NH3(g)
How many grams of N2 are necessary to produce 6.46 g of NH3?
