Question

Write the equation to represent the combustion of propane.

Answer 1

Step 1: Introduction

The combustion of hydrocarbon is to give Carbon dioxide $\left({\mathrm{CO}}_2\right)$ and Water $\left({\mathrm{H}}_2\mathrm{O}\right)$ and evolve a large amount of heat is called combustion reaction.

A combustion reaction is an exothermic reaction.

Step 2: Combustion reaction of Propane:

The combustion reaction of Propane $\left({\mathrm{C}}_3{\mathrm{H}}_8\right)$ is written as:

$$\begin{gathered} {\mathrm{C}}_3{\mathrm{H}}_8+5{\mathrm{O}}_2\to 3{\mathrm{CO}}_2+4{\mathrm{H}}_2\mathrm{O}+\mathrm{Heat} \\ \left(\mathrm{Propane}\right)\left(\mathrm{Oxygen}\right)(\mathrm{Carbon}(\mathrm{Water}) \\ \mathrm{dioxide}) \end{gathered}$$
