Question Description

hey, so would these formula be balanced and show the right precipitation as per previous question.

a.  Pb(NO3)2(aq) + 2NH4Cl → 2PbCl2(s) + 2 NH4NO3(aq)

Pb2+(aq)  + NO3-(aq) + , 2NH4+(aq) + 2Cl-(aq) → 2PbCl(s) + 2NH4+(aq) + NO3-(aq)

PbCl→ Pb+ + Cl-

b.  AgNO3 + NaCl → NANO3 + AGCL

AgNO3(aq) + NaCl(aq) ---> AgCl(s) + NaNO3(aq)

Ag+ + NO3- + Na+ + Cl- ---> AgCl(s) + Na+ + NO3- 

Ag+ + Cl- ---> AgCl(s

c.  CaCl2 + K2CO3 →

CaCl2 (aq) + K2CO3 (aq) --> 2KCl (aq) + CaCO3 (s)
2K+ (aq) + 2CO3- (aq) + Ca2+ (aq) + 2Cl- (aq) --> CaCO3 (s) + 2K+ (aq) + 2Cl- (aq)
CaCO3 (s)  --> 2CO3- (aq) + Ca2+ (aq)

d.  KOH + Fe(NO3)3 →

3KOH(aq) + Fe(NO3)3(aq)→ Fe(OH)3(s) + 3KNO3(aq) 

3k(aq) + OH(aq) + Fe(aq) + NO(aq)  → FeOH(s) + k(aq) + NO(aq)

FeOH → Fe+ + OH-

if not can you fix them up and tell me whati did wrong ?
