Answer 1

Li + O2 = Li2O
Li2O + H2O = LiOH
LiOH + Na2S = Li2S + NaOH
Li2S + Na3PO4 = Li3PO4 + Na2S

Zn + O2 = ZnO
ZnO + N2O5 = Zn(NO3)2
Zn(NO3)2 + Na2SO4 = ZnSO4 + NaNO3
ZnSO4 + NaOH = Zn(OH)2 + Na2SO4
Zn(OH)2 + NaCl = ZnCl2 + NaOH

N2 + O2 = N2O5
N2O5 + HCl = HNO3 + Cl2
HNO3 + CaCl = Ca(NO3)2 + HCl
Ca(NO3)2 + Na2CO3 = CaCO3 + NaNO3
CaCO3 + HCl = H2CO3+ CaCl

P + O2 = P2O5
P2O5 + HNO3 = H3PO4 + N2O5
H3PO4 + LiCl = Li3PO4 + HCl
Li3PO4 + HNO3 = LiNO3 + H3PO4
LiNO3 + HCl = HNO3 + LiCl

Zn(OH)2 --> ZnO + O2
ZnO + HCl = ZnCl2+ H2O
ZnCl2 + Na3PO4 = Zn3(PO4)2 + NaCl
Zn3(PO4)2 + NaNO3 = Zn(NO3)2 + Na3PO4
Zn(NO3)2 + NaOH = Zn(OH)2 + NaNO3
Zn(OH)2 + Na2SO4 = ZnSO4 + NaOH
