Chapter 5, Problem 5.91E

What is the net ionic equation of the following transformations?

$\text{Ca}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}\left(\text{aq}\right)+2\text{KCl}\left(\text{aq}\right)\to {\text{CaCl}}_{\text{2}}\left(\text{s}\right)+2{\text{KNO}}_{\text{3}}\left(\text{aq}\right)$

a. $2{\text{NO}}_3{}^{-}\left(\text{aq}\right)+2{\text{K}}^{+}\left(\text{aq}\right)\to 2{\text{KNO}}_{\text{3}}\left(\text{aq}\right)$

b. ${\text{Ca}}^{2+}\left(\text{aq}\right)+2{\text{Cl}}^{-}\left(\text{aq}\right)\to {\text{CaCl}}_{\text{2}}\left(\text{s}\right)$

c. $\begin{array}{l}{\text{Ca}}^{2+}\left(\text{aq}\right)+2{\text{NO}}_3{}^{-}\left(\text{aq}\right)+2{\text{K}}^{+}\left(\text{aq}\right)+2{\text{Cl}}^{-}\left(\text{aq}\right)\to \\ {\text{CaCl}}_{\text{2}}\left(\text{s}\right)+2{\text{K}}^{+}\left(\text{aq}\right)+2{\text{NO}}_3{}^{-}\left(\text{aq}\right)\end{array}$

d. $\begin{array}{l}{\text{Ca}}^{2+}\left(\text{aq}\right)+2{\text{NO}}_3{}^{-}\left(\text{aq}\right)+2{\text{K}}^{+}\left(\text{aq}\right)+2{\text{Cl}}^{-}\left(\text{aq}\right)\to \\ {\text{Ca}}^{2+}\left(\text{aq}\right)+2{\text{Cl}}^{-}\left(\text{aq}\right)+2{\text{K}}^{+}\left(\text{aq}\right)+2{\text{NO}}_3{}^{-}\left(\text{aq}\right)\end{array}$
