(a)

Interpretation Introduction

Interpretation:

The possible product and the balanced chemical equation of the following redox reaction are to be written.

$\text{Pentane}\left({\text{C}}_5{\text{H}}_{12}\right)+\text{oxygen}\to$

Concept introduction:

A redox reaction is a type of reaction that involves the change in oxidation number of a molecule, atom or ion changes due to the transfer of an electron from one species to another.

A combustion reaction is that reaction in which reactant is reacted with molecular oxygen to form the product. Heat is released and the energy is produced in the reaction. Molecular oxygen is employed as an oxidizing agent in these reactions.

(e)

Interpretation Introduction

Interpretation:

The balanced net ionic equation for the following reaction is to be written.

$\text{Aqueous potassium iodide}+\text{bromine}\to$

Concept introduction:

There are three types of equations that are utilized to represent an ionic reaction:

1. Molecular equation

2. Total ionic equation

3. Net ionic equation

The molecular equation represents the reactants and products of the ionic reaction in undissociated form. In total ionic reaction, all the dissociated ions that are present in the reaction mixture are represented and in net ionic reaction, the useful ions that participate in the reaction are represented.

Spectator ions are the ions that are not a part of the actual chemical change but are present in the reaction mixture to balance the charge on both sides of the reaction. They are represented in the total ionic reaction. These are the dissolved ions present in the reaction mixture.
