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
