When nh3(g) reacts with n2o(g) to form n2(g) and h2o(g), 105 kcal of energy are evolved for each mole of nh3(g) that reacts. write a balanced equation for the reaction with an energy term in kcal as part of the equation.

Answer : The balanced chemical equation is,

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,

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 , the coefficient 3 is put before the and the coefficient 4 is put before the .

The energy evolved in this reaction =

Thus, the balanced chemical reaction will be,
