Chapter 8.1, Problem 3PP

(a)

Interpretation Introduction

Interpretation: Determine whether the following equation is balanced or not balanced:

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

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.

(b)

Interpretation Introduction

Interpretation: Determine whether the following equation is balanced or not balanced:

  $\text{Al}\left(\text{s}\right){\text{ + Cl}}_{\text{2}}\left(\text{g}\right)\to {\text{AlCl}}_{\text{3}}\left(\text{s}\right)$

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: Determine whether the following equation is balanced or not balanced:

  $\text{2NaOH}\left(\text{aq}\right){\text{ + H}}_{\text{2}}{\text{SO}}_{\text{4}}\left(\text{aq}\right)\to {\text{2H}}_{\text{2}}\text{O}\left(\text{l}\right){\text{ + Na}}_{\text{2}}{\text{SO}}_{\text{4}}\left(\text{aq}\right)$

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

Interpretation: Determine whether the following equation is balanced or not balanced:

  ${\text{C}}_{\text{3}}{\text{H}}_{\text{8}}\left(\text{g}\right){\text{ + 5O}}_{\text{2}}\left(\text{g}\right)\to {\text{3CO}}_{\text{2}}\left(\text{g}\right){\text{ + 4H}}_{\text{2}}\text{O}\left(\text{g}\right)$

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.
