Consider the balanced equation below. 4NH3 + 3O2 --> 2N2 + 6H2O What is the mole ratio of NH3 to N2?

The balanced equation given is:
4NH3 + 3O2 .....> 2N2 + 6H2O

From this equation, we can note that 4 moles of NH3 are required to produce 2 moles of N2.

Therefore, the mole ratio of NH3 to N2 is 4:2 which can be simplified into 2:1

Answer : The mole ratio of [tex]NH_3:N_2[/tex] is, 2 : 1

Explanation :

As we are given the balanced chemical reaction. Now we have to determine the mole ratio of [tex]NH_3\text{ to }N_2[/tex]

The given balanced chemical reaction is,

[tex]4NH_3+3O_2\rightarrow 2N_2+6H_2O[/tex]

By the stoichiometry we can say that, 4 moles of ammonia [tex](NH_3)[/tex] react with 3 moles of oxygen gas [tex](O_2)[/tex] to give 2 moles of nitrogen gas [tex](N_2)[/tex] and 6 moles of water [tex](H_2O)[/tex].

From this we conclude that,

The mole ratio of [tex]NH_3:N_2[/tex] is, 4 : 2 or, 2 : 1

Therefore, the mole ratio of [tex]NH_3:N_2[/tex] is, 2 : 1
