Question

1. Balance the chemical reaction for the production of hydrogen cyanide: __ NH3(g) + __ O2(g) + __ CH4(g) → __ HCN(g) + __ H2O(g)
(Hint: none of the coefficients are larger than 6)

2.Using the balanced equation in question 1, if 25.1 g of ammonia are reacted, how many grams of hydrogen cyanide will be produced

Answer 1

2 NH₃ + 3 O₂ + 2 CH₄ ⇒ 2 HCN + 6 H₂O
2mol                     :           2mol
34g                       :           54g
25,1g                    :           x

x = (25,1g * 54g) / 34g ≈ 39,9g
