Chapter 8.3, Problem 6RQ

Interpretation Introduction

Interpretation :

The reaction of hydrogen gas and oxygen gas must be classified in three different ways.

Concept Introduction :

Hydrogen reacts with oxygen gas to produce water.

Answer to Problem 6RQ

The reaction of hydrogen gas and oxygen gas can be classified in the following three ways:

• Combination reaction
• Combustion reaction
• Oxidation-reduction reaction

Explanation of Solution

  ${\text{H}}_{\text{2}}\text{(g)+}\frac{\text{1}}{\text{2}}{\text{O}}_{\text{2}}\text{(g)}\to {\text{H}}_{\text{2}}\text{O(g)}$

In this reaction, hydrogen is combined with oxygen to produce water. Thus, it is a combination reaction.

Hydrogen is combusted in the presence of oxygen. Thus, it is a combustion reaction.

Hydrogen is oxidized and oxygen is reduced. Thus, it is an oxidation-reduction reaction.
