The catalytic conversion of ammonia to nitric oxide is the first step in a three-step process, which ultimately results in nitric acid. Balance the equation for the reaction. NH3(g) + O2(g) → NO(g) + H2O(g)
a. 2, 1, 2, 1
b. 3, 2, 3, 3
c. 4, 3, 2, 6
d. 4, 5, 4, 6​

Respuesta :

The answer is B- 3,2,3,3

The balance equation for the reaction is

4NH₃(g) + 5O₂(g) —> 4NO(g) + 6H₂O(g)  

The coefficients are 4, 5, 4, 6

Option D. 4, 5, 4, 6​ gives the correct answer to the question.

From the question given above, we obtained:

NH₃ + O₂ —> NO + H₂O

The above equation can be balance as illustrated below:

NH₃ + O₂ —> NO + H₂O

There are 2 atoms of H on the right side and 3 atoms on the left side. It can be balance by writing 4 before NH₃ and 6 before H₂O as shown below:

4NH₃ + O₂ —> NO + 6H₂O

There are 4 atoms of N on the left side and 1 atom on the right side. It can be balance by writing 4 before NO as shown below:

4NH₃ + O₂ —> 4NO + 6H₂O

There are 2 atoms of O on the left side and a total of 10 atoms on the right side. It can be balance by writing 5 before O₂ as shown below:

4NH₃(g) + 5O₂(g) —> 4NO(g) + 6H₂O(g)

Now, the equation is balanced.

The coefficients are 4, 5, 4, 6

Thus, Option D. 4, 5, 4, 6​ gives the correct answer to the question.
