Answer #1

Molecular : CrCl3 (aq) + Na3PO4 (aq) ------> CrPO4 (s) + 3 NaCl (aq)

Total Ionic: Cr3+ + 3Cl- + 3 Na+ + PO43- ------> CrPO4 + 3Na+ + 3Cl-

Net Ionic: Cr3+ + PO43- ------> CrPO4

2) Molecular : 2 HBr (aq) + Ba(OH)2 (aq) -----> BaBr2 (s) + 2H2O (l)

Total ionic : 2H+ + 2Br- + Ba2+ + 2OH- ---------> BaBr2 + H2O

Ner ionic : 2H+ + 2Br- + Ba2+ + 2OH- ---------> BaBr2 + H2O
