Question

Hydrogen cyanide (boiling temp 26C) is an important chemical for the production of nylon and various transparent plastics. It is produced on an industrial scale by the oxidation of methane in the presence of ammonia. The equation below is an unbalanced form of the chemical reaction to produce hydrogen cyanide.
I have to write a balanced equation and the steps to balance it. I have to assume that the reaction occurs at a temp above 100C

CH4 + NH3 + O2 = HCN + H2O

Answer 1

In order to balance the reaction follow these steps:
1) First balance the Hydrogen atoms
2) Then balance the oxygen atoms

2CH4 + 2NH3 + 3O2 = 2HCN + 6H2O

Since Hydrogen cyanide (boiling temp 26C) and the reaction occurs at a temp above 100C

2CH4(g) + 2NH3(g) + 3O2(g) = 2HCN(g) + 6H2O(g)

The above is a completely balanced reaction.

Answer 2

CH4 + NH3 +3/2 O2--->HCN +3H2O
To obtain that result you see that you must have an equal number of CH4 and NH3 since HCN has one C and one N.
You see then the 2HCN are formed you have 6H left and 6H +O2 give 3H2O
