hi i just need someone to tell me if these equations are correct if not can you please show me how to get the correct answer.Complete and balance the
following double displacement reactions and indicate the formation of any precipitates by considering the
solubility of the salts produceda. 
Ba(NO3)2 + Na2SO4 →   Ba(NO3)2 + Na2SO4 →  BaSO4 + NaNO3 Ba(NO3)2(aq) + Na2SO4(aq) →  BaSo4(s) + 2NaNO3(aq)Ba2+
(aq) + 2NO-3 (aq) + 2Na+ (aq) + SO4-(aq) → BaSO4(s) + 2Na+
(aq) + 2NO3-(aq)BaSO4→  Ba+ + SO4-b. 
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-c.  AgNO3 + NaCl → NANO3 + AGCLAgNO3(aq) +
NaCl(aq) —> AgCl(s) + NaNO3(aq)Ag+ + NO3- + Na+ +
Cl- —> AgCl(s) + Na+ + NO3- Ag+ + Cl- —> AgCl(sd. 
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) e.  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-
