Chapter 9, Problem 83A

Interpretation Introduction

(a)

Interpretation:

A chemical equation for the reaction between two compounds needs to be determined.

Concept introduction:

In a chemical reaction, the reactants are written on the left side of the equation and the product is written on the right side. The product and the reactants contain an arrow between them showing the proceeding of the reaction from the reactants to the products.

Answer to Problem 83A

A chemical equation for the reaction between two compounds shown in the figure is,

${\text{NH}}_{\text{3}}\text{+}{\text{H}}_{\text{2}}\text{O}\rightleftharpoons {\text{NH}}_{\text{4}}\text{OH}$

Explanation of Solution

From the figure, one can see that, ammonia and water combine to give product ammonium hydroxide.

${\text{NH}}_{\text{3}}\text{+}{\text{H}}_{\text{2}}\text{O}\rightleftharpoons {\text{NH}}_{\text{4}}\text{OH}$

(b)

Interpretation Introduction

Interpretation:

The reaction given in the figure needs to be classified.

Concept introduction:

In a chemical reaction, the reactants are written on the left side of the equation and the product is written on the right side. The product and the reactants contain an arrow between them showing the proceeding of the reaction from the reactants to the products.

Answer to Problem 83A

The reaction ${\text{NH}}_{\text{3}}\text{+}{\text{H}}_{\text{2}}\text{O}\rightleftharpoons {\text{NH}}_{\text{4}}\text{OH}$ is a synthesis reaction.

Explanation of Solution

In the reaction, ${\text{NH}}_{\text{3}}\text{+}{\text{H}}_{\text{2}}\text{O}\rightleftharpoons {\text{NH}}_{\text{4}}\text{OH}$

Two reactants combined to give one product. Therefore, this is a synthesis reaction.
