Explanation / Answer

Reactions

1. Co(NO3)2 + BaCl2 ---> CoCl2 + Ba(NO3)2

2. MnBr2 + 2KOH ---> Mn(OH)2 + 2KBr

3. 2CH3COOK + BaS ---> (CH3COO)2Ba + K2S

4. BaS + 2CH3COOK ----> (CH3COO)2Ba + K2S

5. 2CrI3 + 3(NH4)2S ----> Cr2S3 + 6NH4I

6. 3NH4Br + K3PO4 ---> (NH4)3PO4 + 3KBr

7. K3PO4 + 3NaOH ---> 3KOH + Na3PO4

8. FeI3 + Na3PO4 ---> FePO4 + 3NaI

9. 2CH3COOK + Ba(OH)2 ---> (CH3COO)2Ba + 2KOH

10. Ba(OH)2 + 2CH3COONa ----> (CH3COO)2Ba + 2NaOH

11. net ionic : 3CH3COO- + Cr3+ ---> (CH3COO)3Cr

12. net ionic : Fe3+ + 3Br- ----> FeBr3
