Chapter 7, Problem 25A

Interpretation Introduction

Interpretation:

The unbalanced chemical equation corresponding to the synthesis of ammonium nitrate from ammonia and nitric acid needs to be presented.

Concept Introduction:

• A chemical reaction is expressed as a chemical equation having reactants and products on left and right side of the reaction arrow respectively.

  $\text{Reactants }\to \text{ Products}$

• It also gives the physical state (solid (s), liquid (l), gas (g) and the amount of reactants and products involved in the reaction.

Answer to Problem 25A

  ${\text{NH}}_3{\text{(g) + HNO}}_3\text{(g) }\to {\text{ NH}}_4{\text{NO}}_3\text{(s) }$

Explanation of Solution

The given process involves the reaction between gaseous ammonia and nitric acid to produce solid ammonium nitrate. The reactants and products are:

Reactants:

  $\begin{array}{l}{\text{Ammonia, gas - NH}}_3(\text{g})\\ {\text{Nitric acid, gas - HNO}}_3\text{ (g)}\end{array}$

Products:

  ${\text{Ammonium nitrate, solid - NH}}_4{\text{NO}}_3\text{(s)}$

Unbalanced equation:

  ${\text{NH}}_3{\text{(g) + HNO}}_3\text{(g) }\to {\text{ NH}}_4{\text{NO}}_3\text{(s) }$

Conclusion

Therefore, the unbalanced reaction will have gaseous ammonia and nitric acid as the reactants with ammonium nitrate as the product.
