Chapter 24, Problem 47QP

Interpretation Introduction

Interpretation:

The balanced equation for the formation of urea from carbon dioxide and ammonia is to be explained. To maximize the yield of urea the pressure should be kept low or high is to be determined.

Concept introduction:

A chemical reaction consists of the atoms or molecules that combine with each other to give a product.

Reactants are written in left side of chemical reaction and products are written in right side of chemical reaction.

In a balanced chemical reaction, the number of atoms on both sides of the reaction is the same. Thus, the masses of the reactant are equal to the masses of the product.

Urea is also known as carbamide, in which the two ${\text{NH}}_2$ groups are attached to the carbonyl group.

In the urine of a mammal, urea is the main nitrogen containing substance.
