Chapter 4, Problem 4.64QP

(a)

Interpretation Introduction

Interpretation:

The given equation ${\text{Fe}}_{\text{2}}{\text{O}}_{\text{3(s)}}{\text{ + CO}}_{\text{(g)}}\stackrel{}{\to }{\text{ Fe}}_{\text{3}}{\text{O}}_{\text{4(s)}}{\text{ + CO}}_{\text{2(g)}}$ has to be balanced.

Concept Introduction:

Balancing the equation:

• There is a Law for conversion of mass in a chemical reaction i.e., the mass of total amount of the product should be equal to the total mass of the reactants.
• First write the skeletal reaction from the given information.
• Then count the number of atoms of each element in reactants as well as products.
• Place suitable coefficients in front of reactants as well as products until the number of atoms on each side (reactants and products) becomes equal.

(b)

Interpretation Introduction

Interpretation:

The given equation ${\text{C}}_{\text{6}}{\text{H}}_{\text{6(l)}}{\text{ + O}}_{\text{2(g)}}\stackrel{}{\to }{\text{ CO}}_{\text{2(g)}}{\text{ + H}}_{\text{2}}{\text{O}}_{\text{(g)}}$ has to be balanced.
