Chapter 8, Problem 8PE

(a)

Interpretation Introduction

Interpretation:

The balanced and completed equation for the combustion reaction of butane has to be given.

Concept Introduction:

Combustion reactions:  Reactions in which a substance reacts with oxygen to form oxides are called as combustion reaction.  In a combustion reaction, the reactants are mostly hydrocarbons and oxygen, the products obtained are carbon dioxide and water.  Combustion reactions are used in the generation of energy from fossil fuels.

Example:  Combustion of methane yields carbon dioxide and water as products.

  ${\text{CH}}_{\text{4}}\left(\text{g}\right){\text{+2O}}_{\text{2}}\left(\text{g}\right)\stackrel{}{\to }{\text{CO}}_{\text{2}}\left(\text{g}\right){\text{+2H}}_{\text{2}}\text{O}\left(\text{g}\right)$

Combustion reactions can be identified by the presence of oxygen in the reactants in a chemical reaction.
