Neutralization Reactions

Answer 1

The reactions that occur are:

1) 2 AgNO3 + K2CO3 = Ag2CO3 + 2 KNO3

2) Cu (NO3) 2 + K2CO3 = CuCO3 + 2 KNO3

3) 2 Al (NO3) 3 + 3 K2CO3 = Al2 (CO3) 3 +

6 KNO3

4) 3 AgNO3 + Na3PO4 = Ag3PO4 + 3 NaNO3

5) 3 Cu (NO3) 2 + 2 Na3PO4 = Cu3 (PO4) 2 + 6 NaNO3

6) 2 Al (NO3) 3 + 3 Na3PO4 = Al2 (PO4) 3 + 6 NaNO3
