Interpretation Introduction

Interpretation

Characterization of the combustion reaction has to be chosen from the given option.

Concept Introduction

Combustion reaction:

It is a type of chemical reaction between oxygen and a substance that results in the evolution of heat and light or it is a reaction between a combustible product and an oxidizer (oxygen).  Combustion is an exothermic process because it liberates heat.  It usually occurs with hydrocarbons.  Hydrocarbons on reaction with oxygen gives carbondioxide and water. 

Example:

  ${\text{CH}}_{\text{4}}{\text{+2O}}_{\text{2}}\to {\text{CO}}_{\text{2}}{\text{+2O}}_{\text{2}}$

Methane on reaction with two molecules of oxygen gives carbondioxide and water.
