cmplete and balance the following. for each write molecular and net ionic. (think about which products are soluble in water).
A)Ferrous chloride(aq) reacts with lithium chloride(aq)
B) aqueous barium chloride reacts with silver nitrate(aq)
C) K2S(aq)+PbCl2(aq)----->?
a)
Ferrous = Fe+2
chloride = cl-
FeCl2(aq) + LiCl(aq) --> LiCl(aq) + FeCl2(aq)
no reaction , all remains in solution
b)
BaCl2(aq) + AgNO3(aq) --> AgCl(s) + Ba(NO3)2(aq)
balance
BaCl2(aq) + 2AgNO3(aq) --> 2AgCl(s) + Ba(NO3)2(aq)
net ionic:
2Cl-(aq) + 2Ag+(aq) --> 2AgCl(s)
c)
PbS is not soluble so:
K2S(aq)+PbCl2(aq) --> PbS(s) + KCl(aq)
balance
K2S(aq)+PbCl2(aq) --> PbS(s) + 2KCl(aq)
split ionic:
2K+(aq) + S-2(aq)+Pb+2(aq) + 2Cl-(aq) --> PbS(s) + 2K+(aq) + 2Cl-(aq)
get rid of ionic species
S-2(aq)+Pb+2(aq) --> PbS(s)
