1) 4P + 5O2 =2P2O5
P2O5 + 3H2O= 2H3PO4
3ZnCL2+2H3PO4=Zn3(PO4)2 + 6HCL
Zn3(PO4)2 + 6Na = 2Na3PO4 + 3Zn
2Zn+O2=2ZnO
ZnO + H2SO4 =ZnSO4 + H2O
ZnSO4+ BaCL2=BaSO4 + ZnCL2
2)2Mg+O2=2MgO
3MgO+ 2H3PO4=Mg3(PO4)2 + 3H2O
Mg3(PO4)2 + 6NaOH= 3Mg(OH)2+ 2Na3PO4
Mg(OH)2+2HNO3=Mg(NO3)2+ 2H2O
Mg(NO3)2 + 2Li= 2LiNO3 + Mg
Mg + 2HCL=MgCL2 + H2
MgCl2 + 2AgNO3= 2AgCl + Mg(NO3)2
