Answer 1

1- Reaction of Silver Nitrate (AgNO3) and Hydrochloric acid (HCl) is

AgNO3 (aq) + HCl (aq) ------------> HNO3 (aq) + AgCl (s)

Ionic equation : Here all the aqueous compounds dissociate into their constituent ions-

i.e Ag+(aq) + NO3- (aq) + H+(aq) + Cl- (aq) ------------> NO3- (aq) + H+(aq) + AgCl (s)

Net ionic equation: By eliminating the common ions from both sides of ionic equation, we get Net ionic equation

i.e  Ag+(aq) + Cl- (aq) ------------> AgCl (s)

2- Reaction of Sodium Chloride (NaCl) and Potasium Bromide (KBr) is

NaCl (aq) + KBr (aq) ------------> NaBr (aq) + KCl (aq)

Ionic equation : Here all the aqueous compounds dissociate into their constituent ions-

i.e Na+(aq) + Cl- (aq) + K+(aq) + Br- (aq) ------------> Na+ (aq) +Br-(aq) + K+(aq) + Cl- (aq)

Net ionic equation: By eliminating the common ions from both sides of ionic equation, we get Net ionic equation

i.e No reaction

3- Reaction of Sosium Carbonate (Na2CO3) and Barium chloride (BaCl2) is

Na2CO3 (aq) + BaCl2 (aq) ------------> 2NaCl (aq) + BaCO3 (s)

Ionic equation : Here all the aqueous compounds dissociate into their constituent ions-

i.e 2Na+(aq) + CO3-2 (aq) + Ba+2(aq) + 2Cl- (aq) ------------> 2Na+(aq) + 2Cl- (aq) + BaCO3 (s)

Net ionic equation: By eliminating the common ions from both sides of ionic equation, we get Net ionic equation

i.e  Ba+2(aq) + CO3-2 (aq) ------------> BaCO3 (s)
