Answer #1

1) Molecular :

2Na3PO4 (aq) + 3FeSO4(aq) 3Na2SO4 (aq) + Fe3(PO4)2(s)

Ionic :

6Na+(aq) + 2PO43-(aq) + 3Fe2+(aq) + 3SO42-(aq) 6Na+(aq) + 3SO42-(aq) + Fe 3(PO4)2(s)

Net Ionic : 3Fe2+(aq) + 2PO43-(aq) Fe3(PO4)2(s)

2) Molecular :

3(NH4)2CO3(aq) + 2Cr(NO3)3(aq) Cr2(CO3)3(s) + 6NH4NO3 (aq)

Ionic :

6NH4+(aq) + 3CO32-(aq) + 2Cr3+(aq) + 6NO3-(aq) Cr2(CO3)3(s) + 6NH4+(aq) + 6NO3-(aq)

Net Ionic : 2Cr3+(aq) + 3CO32-(aq) Cr2(CO3)3(s)
