(a)

Interpretation Introduction

Interpretation: Balance the following chemical equations:

  $\text{K}\left(\text{s}\right){\text{ + H}}_{\text{2}}\text{O}\left(\text{l}\right)\to {\text{H}}_{\text{2}}\left(\text{g}\right)\text{ + KOH}\left(\text{aq}\right)$

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:

  $\text{Cr}\left(\text{s}\right){\text{ + S}}_{\text{8}}\left(\text{s}\right)\to {\text{Cr}}_{\text{2}}{\text{S}}_{\text{3}}\left(\text{s}\right)$

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:

  ${\text{BCl}}_{\text{3}}\left(\text{s}\right){\text{ + H}}_{\text{2}}\text{O}\left(\text{l}\right)\to {\text{H}}_{\text{3}}{\text{BO}}_{\text{3}}\left(\text{aq}\right)\text{ + HCl}\left(\text{aq}\right)$

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)
