(a)

Interpretation Introduction

Interpretation: Balance the following chemical equations:

  $\text{Zn}\left(\text{s}\right){\text{ + HNO}}_{\text{3}}\left(\text{aq}\right)\to {\text{H}}_{\text{2}}\left(\text{g}\right)\text{ + Zn}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}\left(\text{aq}\right)$

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.

(b)

Interpretation Introduction

Interpretation: Balance the following chemical equations:

  $\text{Al}\left(\text{s}\right){\text{ + H}}_{\text{2}}{\text{SO}}_{\text{4}}\left(\text{aq}\right)\to {\text{H}}_{\text{2}}\left(\text{g}\right){\text{ + Al}}_{\text{2}}{\left({\text{SO}}_{\text{4}}\right)}_{\text{3}}\left(\text{aq}\right)$

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.

(c)

Interpretation Introduction

Interpretation: Balance the following chemical equations:

  ${\text{K}}_{\text{2}}{\text{SO}}_{\text{4}}\left(\text{aq}\right){\text{ + BaCl}}_{\text{2}}\left(\text{aq}\right)\to {\text{BaSO}}_{\text{4}}\left(\text{s}\right)\text{ + KCl}\left(\text{aq}\right)$

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.

(d)

Interpretation Introduction
