Chapter 15, Problem 30PE

(a)

Interpretation Introduction

Interpretation:

The indicated equation has to be balanced and then converted to net ionic equation.

  $\text{Mg}\left(s\right)+\text{Cu}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}\left(aq\right)\to \text{Cu}\left(s\right)+\text{Mg}{\left({\text{NO}}_{\text{3}}\right)}_2\left(aq\right)$

Concept Introduction:

The ionic equation can be written based on the rules as follows:

• Strong electrolytes dissociate completely into ionic forms.
• Weak electrolytes remain in molecular form.
• Nonelectrolytes remain in molecular form.
• Insoluble precipitates and gases remain in molecular forms.
• The net ionic equation includes only ions that have reacted and thus any spectator ions are usually omitted.

(b)

Interpretation Introduction

Interpretation:

The indicated equation has to be balanced and then converted to net ionic equation.

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

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

The indicated equation has to be balanced and then converted to net ionic equation.

  ${\text{K}}_{\text{2}}{\text{SO}}_{\text{3}}\left(aq\right)+{\text{HClO}}_4\left(aq\right)\to {\text{KClO}}_{\text{4}}\left(aq\right)+{\text{H}}_{\text{2}}\text{O}\left(l\right)+{\text{SO}}_{\text{2}}\left(g\right)$
