Question

Two examples of the Double Displacement Reaction​

Answer 1

Answer:

AD+C _CB+A DOUBLE DISPLACEMENT

AB+CD_CB+AD DOUBLE DISPLACEMENT

BaCL2 +NaSo4___2NaCL+BaSo4

FeS+H2So4___H2S+FeSo4

I think this is hepl tou

Answer 2

i. AgNO³ +Nacl -> AgCl + NaNO³

ii. NH4OH + HCl -> NH4Cl + H²O

i. when silver nitrate dissolve with sodium chloride the highly reactive metal i.e. sodium displaces silver and forms precipitates i.e. AgCl(silver chloride) and sodium nitrate(aq.)

ii. When ammonia solution (base) disolves with hydrochloric acid, ammonia displaces hydrogen and forms ammonia chloride (salt) and water which neutralize the reaction and is called double displacement and neutralisation reaction.
