Question

Complete and balance the following chemical equation:

${\mathrm{CH}}_4+{\mathrm{O}}_2\to {\mathrm{CO}}_2+\mathrm{\_}+\mathrm{Heat}$

Answer 1

A combustion reaction occurs when fuel is oxidized by reacting with an oxidizing agent and releasing energy is called combustion reaction.

The combustion reaction of Methane $\left({\mathrm{CH}}_4\right)$ in the presence of two moles of Oxygen $\left({\mathrm{O}}_2\right)$ forms Carbon dioxide $\left({\mathrm{CO}}_2\right)$ and two moles of Water $\left({\mathrm{H}}_2\mathrm{O}\right)$ with the generation of heat.

The complete and balanced chemical equation of the combustion reaction of Methane is written as:

$$\begin{gathered} {\mathrm{CH}}_4\left(\mathrm{g}\right)+2{\mathrm{O}}_2\left(\mathrm{g}\right)\to {\mathrm{CO}}_2\left(\mathrm{g}\right)+2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)+\mathrm{Heat} \\ \left(\mathrm{Methane}\right)\left(\mathrm{Oxygen}\right)(\mathrm{Carbon}(\mathrm{Water}) \\ \mathrm{dioxide}) \end{gathered}$$
