Chapter 19.2, Problem 18R

To determine

To write: the balance equation for the given reaction.

Explanation of Solution

Introduction:

The chemical reaction is a process in which the materials are converted to one or more separate compounds, the reactants. The substances are either compounds or chemical elements. In Balanced equations, coefficient in reactant and product are same in number.

Sulfur trioxide reacts with water molecules results sulfuric acid. The reaction is,

  ${\text{SO}}_{\text{3}}\left(\text{g}\right){\text{+H}}_{\text{2}}\text{O}\left(\text{l}\right)\to {\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}$

This reaction is already balanced. Therefore, the balance reaction will be,

  ${\text{SO}}_{\text{3}}\left(\text{g}\right){\text{+H}}_{\text{2}}\text{O}\left(\text{l}\right)\to {\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}$

Conclusion:

Hence, the required balance equation is, ${\text{SO}}_{\text{3}}\left(\text{g}\right){\text{+H}}_{\text{2}}\text{O}\left(\text{l}\right)\to {\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}$ .
