Hydrogen cyanide, HCN, is prepared from ammonia, air, and natural gas (CH4) by the following process: Pt 2NH3 (g) + 30, (9) + 2CH, (g) → 2HCN(9) + 6H,O(g) Hydrogen cyanide is used to prepare sodium cyanide, which is used in part to obtain gold from gold-containing rock. If a reaction vessel contains 5.96 g NH3, 14.0 g O2, and 6.67 g CH4, what is the maximum mass in grams of hydrogen cyanide that could be made, assuming the reaction goes to completion as written? Mass = g HCN
