1)
Na3PO4 +
KOH →
NaOH +
K3PO4
2)
MgF2+
Li2CO3 →
MgCO3 +
LiF
3)
PA+
O2 →_P203
4)
RbNO3 +
BeF2 →
Be(NO3)2 +
RbF
5)
AgNO3 +
Cu →
- Cu(NO3)2 +
Ag

Answer 1

1) Na3PO4 (aq) + 3 KOH (aq) → 3 NaOH (aq) + K3PO4 (aq)

Displacement Reaction

2)MgF2 (s) + Li2CO3 (s) → MgCO3 (s) + 2 LiF (s)

Displacement Reaction

3) I don't know

4)2 RbNO3 + BeF2 → Be(NO3)2 + 2 RbF

5)2 AgNO3 (aq) + Cu (s) → Cu(NO3)2 (aq) + 2 Ag (s)
