Answer: The equation [tex]N_{2}H_{4} + N_{2}O_{4} \rightarrow 3N_{2} + 4H_{2}O[/tex] is not a balanced equation.
Explanation:
A chemical equation which contains same number of atoms on both reactant and product side is called a balanced chemical equation.
For example, [tex]N_{2}H_{4} + N_{2}O_{4} \rightarrow 3N_{2} + 4H_{2}O[/tex]
Here, number of atoms on reactant side are as follows.
Number of atoms on product side are as follows.
Since, the number of atoms present on reactant side are not equal in number as compared to the atoms present on product side. Hence, this equation is not balanced.
Thus, we can conclude that the equation [tex]N_{2}H_{4} + N_{2}O_{4} \rightarrow 3N_{2} + 4H_{2}O[/tex] is not a balanced equation.
