Interpretation Introduction

(a)

Interpretation:

Balance the following chemical equations:

Concept Introduction:

The reactions for those the number of atoms of each element in the product and reactant side are equal, such reactions are said to be a balanced chemical equation.

Interpretation Introduction

(b)

Interpretation:
