Chapter 7, Problem 69P(choose chapter or problem)
Correct any incorrect equations. If no reaction occurs, write NO REACTION.
(a) \(\mathrm{Ba}\left(\mathrm{NO}_{3}\right)_{2}(a q)+\left(\mathrm{NH}_{4}\right)_{2} \mathrm{SO}_{4}(a q) \rightarrow \mathrm{BaSO}_{4}(s)+2 \mathrm{NH}_{4} \mathrm{NO}_{3}(a q)\)
(b) \(\mathrm{BaS}(a q)+2 \mathrm{KCl}(a q) \rightarrow \mathrm{BaCl}_{2}(s)+\mathrm{K}_{2} \mathrm{~S}(a q)\)
(c) \(2 \mathrm{KI}(a q)+\mathrm{Pb}\left(\mathrm{NO}_{3}\right)_{2}(a q) \rightarrow \mathrm{PbI}_{2}(s)+2 \mathrm{KNO}_{3}(a q)\)
(d) \(\mathrm{Pb}\left(\mathrm{NO}_{3}\right)_{2}(a q)+2 \mathrm{LiCl}(a q) \rightarrow 2 \mathrm{LiNO}_{3}(s)+\mathrm{PbCl}_{2}(a q)\)

ANSWER:Solution 69P
Here, we have to correct any incorrect equations and if no reaction occurs, write NO REACTION.
(a) Ba(NO3)2(aq) + (NH4)2SO4(aq) → BaSO4(s) + 2 NH4NO3(aq) :
The above equation is correct. The products formed - BaSO4 is insoluble in water and hence the precipitation equation is correct.
(b) BaS(aq) + 2 KCl(aq) &
