Chapter 7, Problem 68E

Correct any incorrect equations. If no reaction occurs, write NO REACTION.

a. ${\text{AgNO}}_3\left(aq\right)+\text{NaCl}\left(aq\right)\to \text{NaCl}\left(s\right)+{\text{AgNO}}_{\text{3}}\left(aq\right)$

b. ${\text{K}}_{\text{2}}{\text{SO}}_4\left(aq\right)+\text{Co}{\left({\text{NO}}_{\text{3}}\right)}_2\left(aq\right)\to {\text{CoSO}}_{\text{4}}\left(s\right)+2{\text{ KNO}}_{\text{3}}\left(aq\right)$

c. $\text{Cu}{\left({\text{NO}}_{\text{3}}\right)}_2\left(aq\right)+{\left({\text{NH}}_{\text{4}}\right)}_2\text{S}\left(aq\right)\to \text{CuS}\left(s\right)+{\text{2 NH}}_{\text{4}}{\text{NO}}_{\text{3}}\left(aq\right)$

d. ${\text{Hg}}_{\text{2}}{\left({\text{NO}}_{\text{3}}\right)}_2\left(aq\right)+2\text{ LiCl}\left(aq\right)\to {\text{Hg}}_{\text{2}}{\text{Cl}}_{\text{2}}\left(s\right)+{\text{2 LiNO}}_{\text{3}}\left(aq\right)$
