Answer #1

molecular equation :

CrBr2 (aq) + 2 NH4NO3 (aq) ------------------------> 2NH4Br (aq) + Cu(NO3)2 (aq)

complete ionic :

Cr+2 (aq) + 2 Br-(aq) + 2 NH4+ (aq) + 2 NO3- (aq) ----------------> 2 NH4+ (aq) + 2Br-(aq) + Cu+2 (aq) + 2NO3-(aq)

net ionic equation :

Cr+2 (aq) + 2 Br-(aq) + 2 NH4+ (aq) + 2 NO3- (aq) ------------> 2 NH4+ (aq) + 2Br-(aq) + Cu+2 (aq) + 2NO3-(aq)

explanation :

no precipitate is formed in this reaction so total ionic equation is net ionic equation .
