Chapter 7, Problem 69E

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

a. $\text{Ba}{\left({\text{NO}}_3\right)}_2\left(aq\right)+{\left({\text{NH}}_{\text{4}}\right)}_{\text{2}}{\text{SO}}_{\text{4}}\left(aq\right)\to {\text{BaSO}}_{\text{4}}\left(s\right)+{\text{2 NH}}_{\text{4}}{\text{NO}}_{\text{3}}\left(aq\right)$

b. $\text{BaS}\left(aq\right)+\text{2 HCl}\left(aq\right)\to {\text{BaCl}}_{\text{2}}\left(s\right)+{\text{K}}_{\text{2}}\text{S}\left(aq\right)$

c. $\text{2 KI}\left(aq\right)+\text{Pb}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}\left(aq\right)\to {\text{PbI}}_{\left(s\right)}{\text{+2 KNO}}_{\text{3}}\left(aq\right)$

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