Question

Complete and balance the following reaction:

${\text{CH}}_4\text{(g)}+{\text{O}}_2\text{(g)}\to$

• A. ${\text{CH}}_4\text{(g)}+2{\text{O}}_2\text{(g)}\to {\text{CH}}_3\text{O(g)}$
• B. ${\text{CH}}_4\text{(g)}+2{\text{O}}_2\text{(g)}\to {\text{CO}}_2\text{(g)}+2{\text{H}}_2\text{(l)}$
• C. ${\text{CH}}_4\text{(g)}+{\text{O}}_2\text{(g)}\to {\text{CO}}_2\text{(g)}+{\text{H}}_2\text{O (l)}$
• D. ${\text{CH}}_4\text{(g)}+2{\text{O}}_2\text{(g)}\to {\text{CO}}_2\text{(g)}+2{\text{H}}_2\text{O (l)}$

Answer 1

The correct option is D

${\text{CH}}_4\text{(g)}+2{\text{O}}_2\text{(g)}\to {\text{CO}}_2\text{(g)}+2{\text{H}}_2\text{O (l)}$

The given reaction is an example of a combustion reaction in which methane will combine with an oxygen molecule to form carbon dioxide and water. The reaction takes place as follows:

${\text{CH}}_4\text{(g)}+2{\text{O}}_2\text{(g)}\to {\text{CO}}_2\text{(g)}+2{\text{H}}_2\text{O (l)}$
