Answer : The balanced chemical equation is,
[tex]2NH_3(g)+3N_2O(g)\rightarrow 4N_2(g)+3H_2O(g)+210kcal[/tex]
Explanation :
Balanced chemical equation : It is defined as the number of atoms of individual elements present on the reactant side must be equal to the number of atoms of individual elements present on product side.
The given unbalanced chemical reaction is,
[tex]NH_3(g)+N_2O(g)\rightarrow N_2(g)+H_2O(g)+105kcal[/tex]
This chemical reaction is an unbalanced reaction because in this reaction, the number of atoms of individual elements are not balanced.
In order to balanced the chemical reaction, the coefficient 2 is put before the [tex]NH_3[/tex], the coefficient 3 is put before the [tex]N_2O\text{ and }H_2O[/tex] and the coefficient 4 is put before the [tex]N_2[/tex].
The energy evolved in this reaction = [tex]105Kcal\times 2=210Kcal[/tex]
Thus, the balanced chemical reaction will be,
[tex]2NH_3(g)+3N_2O(g)\rightarrow 4N_2(g)+3H_2O(g)+210kcal[/tex]
