Chapter 3, Problem 34P

(a)

Interpretation Introduction

Interpretation:Balanced equations for the combustion of methane should be written.

Concept introduction:When a hydrocarbon is burnt in presence of air the products formed include water vapor and carbon dioxide. This phenomenon is termed as combustion.

The general reaction for combustion of hydrocarbon is as follows:

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

Where,

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

(b)

Interpretation Introduction

Interpretation: Balanced equations for the combustion of propane should be written.

Concept introduction:When a hydrocarbon is burnt in presence of air the products formed include water vapor and carbon dioxide. This phenomenon is termed as combustion.

The general reaction for combustion of hydrocarbon is as follows:

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

Where,

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

(c)

Interpretation Introduction
