Chapter 11, Problem 11.61E

Interpretation Introduction

(a)

Interpretation:

The balanced equation to represent the complete combustion of the given compound is to be stated.

Concept introduction:

Alkane is made of only carbon and hydrogen atoms. These atoms form a bond with each other and with other atoms through the sharing of electrons. They do not completely donate their electrons to other atoms while forming a bond. A general complete combustion reaction of alkanes is shown below as,

${\text{C}}_n{\text{H}}_{2n+2}+\left(\frac{3n+1}{2}\right){\text{O}}_2\to n{\text{CO}}_{\text{2}}+\left(n+1\right){\text{H}}_{\text{2}}\text{O}$

Answer to Problem 11.61E
