1.

HCN(aq) + NiCl2(aq) Ni(CN)2(s) + HCl(aq)

The balanced equation is

2HCN(aq) + NiCl2(aq)   Ni(CN)2(s) + 2HCl(aq)

Ionic equation with all ions

2H+(aq) + 2CN-(aq) + Ni2+(aq) + 2Cl-(aq)   Ni(CN)2(s) + 2H+(aq) +  2Cl-(aq)

Net ionic equation with spectator ions out

2CN-(aq) + Ni2+(aq)    Ni(CN)2(s)

2.

CH3COOH(aq) +  Ba(OH)2(aq)    Ba(CH3COO)2(aq) + H2O(l)

The balanced equation is

2CH3COOH(aq) +  Ba(OH)2(aq)    Ba(CH3COO)2(aq) + H2O(l)

Ionic equation with all ions

2CH3COO-(aq) + 2H+(aq) + Ba2+(aq) + 2OH-(aq) Ba2+(aq) + 2CH3COO- (aq) + 2H2O(l)

Net ionic equation with spectator ions out

2H+(aq) +  2OH-(aq)    2H2O(l)

3.

(NH4)3PO4(aq) + CoBr2(aq)   Co3(PO4)2(s) + NH4Br(aq)

The balanced equation is

2(NH4)3PO4(aq) + 3CoBr2​(aq)   Co3(PO4)2(s) + 6NH4Br(aq)

Ionic equation with all ions

6NH4+(aq) + 2PO43-(aq) + 3Co2+(aq) + 6Br-​(aq)    Co3(PO4)2(s) + 6NH4+(aq)  +  6Br-​(aq)

Net ionic equation with spectator ions out

2PO43-(aq) + 3Co2+(aq)     Co3(PO4)2(s)
