Interpretation Introduction

(a)

Interpretation:

To state the balanced chemical equation for the given reaction.

Concept introduction:

A balanced chemical reaction equation is the one in which the number of atoms of all the elements are equal on both the sides of the chemical equation.

Interpretation Introduction

(b)

Interpretation:

To state the balanced chemical equation for the given reaction.

Concept introduction:

A balanced chemical reaction equation is the one in which the number of atoms of all the elements are equal on both the sides of the chemical equation. An oxidizing agent is the one which has the tendency to oxidize others and itself gets reduced in a chemical reaction.

Interpretation Introduction

(c)

Interpretation:

To state the balanced chemical equation for the given reaction.

Concept introduction:

A balanced chemical reaction equation is the one in which the number of atoms of all the elements are equal on both the sides of the chemical equation. Reduction of a chemical species is said to occur when the oxidation state of the species undergoing reduction decreases due to gain of electrons. An oxidizing agent is the one which has the tendency to oxidize others and itself gets reduced in a chemical reaction.
