Explanation:
A chemical reaction equation that contains same number of atoms on both reactant and product side is known as a balanced equation.
For example, [tex]4NH_{3} + 3O_{2} \rightarrow 2N_{2} + 6H_{2}O[/tex]
Here, number of nitrogen atoms on both reactant and product side is 4.
Number of hydrogen atoms on both reactant and product side is 12.
Number of oxygen atoms on both reactant and product side is 6.
Since, there are 4 moles [tex]NH_{3}[/tex] and 2 moles of [tex]N_{2}[/tex].
Therefore, we can conclude that mole ration of [tex]NH_{3}[/tex] to [tex]N_{2}[/tex] is 4:2 which is equal to 2:1.
