Chapter 11, Problem 11.60E

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 11.60E

The balanced equation to represent the complete combustion of the given compound is shown below as,

${\text{2C}}_4{\text{H}}_{10}+13{\text{O}}_2\to 8{\text{CO}}_{\text{2}}+10{\text{H}}_{\text{2}}\text{O}$

Explanation of Solution

The given molecule is butane. The chemical formula of butane is ${\text{C}}_{\text{4}}{\text{H}}_{\text{10}}$.

A general complete combustion reaction of alkanes is shown below as,

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

Where,

• $n$ represents the number of carbon atoms in the alkane.

The number of carbon atoms in butane is four.

Therefore, the balanced equation to represent the complete combustion of the given compound is shown below as,

${\text{C}}_4{\text{H}}_{10}+\frac{13}{2}{\text{O}}_2\to 4{\text{CO}}_{\text{2}}+5{\text{H}}_{\text{2}}\text{O}$

The reaction is further simplified as,

${\text{2C}}_4{\text{H}}_{10}+13{\text{O}}_2\to 8{\text{CO}}_{\text{2}}+10{\text{H}}_{\text{2}}\text{O}$

Conclusion

The balanced equation to represent the complete combustion of the given compound is shown below as,

${\text{2C}}_4{\text{H}}_{10}+13{\text{O}}_2\to 8{\text{CO}}_{\text{2}}+10{\text{H}}_{\text{2}}\text{O}$
