Interpretation Introduction

(a)

Interpretation:

Balance the following chemical equations:

  ${\text{Fe}}_{\text{2}}{\text{O}}_{\text{3}}\left(\text{s}\right)\text{ + CO}\left(\text{g}\right)\to \text{Fe}\left(\text{s}\right){\text{ + CO}}_{\text{2}}\left(\text{g}\right)$

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:

Balance the following chemical equations:

  ${\text{Li}}_{\text{3}}\text{N}\left(\text{s}\right)\to \text{Li}\left(\text{s}\right){\text{ + N}}_{\text{2}}\left(\text{g}\right)$

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
