One of the intermediates in the synthesis of glycine from ammonia, carbon dioxide, and methane is aminoacetonitrile, C2H4N2. The balanced chemical equation is as follows: 3CH4 (g) + 5CO2 (g) + 8NH3 (g) → 4C2H4N2 (g) + 10H2O (g)
How much C2H4N2 could be expected from the reaction of 13.5 grams of CO2, 2.21 grams of NH3, and 1.65 grams of CH4?
