Chapter 4.4, Problem 1RC

Interpretation Introduction

Interpretation:

The reaction that is not a redox reaction has to be identified.

Concept introduction:

 Redox reaction:

• The oxidation number of a molecule is varied by involving in reaction is called redox reaction. The oxidation and reduction of chemical compounds takes place while they are involving in the reaction.

 Type of redox reaction:

 Combination redox reaction:

• The combination of reactants in the redox reaction is occurring while during the reaction.

 Decomposition redox reaction:

• The decomposition of reactants in the redox reaction is occurring while during the reaction.

Displacement redox reaction:

• The displacement of reactants in the redox reaction is occurring while during the reaction.
• The displacement reaction can be classified into hydrogen displacement, metal displacement and halogen displacement.

 A combustion reaction:

• A combustion reaction is when oxygen combines with another substance to produce water and carbon dioxide, and is an exothermic reaction.

Disproportion reaction:

• Disproportion reaction is the special type of reaction where an element in one oxidation state is simultaneously oxidised and reduced.
