Na➡NaOH➡Na2SO4➡NaCl➡NaNO3
Zn➡ZnO➡ZnCl2➡Zn(OH)2➡ZnSO4➡Zn(OH)2

Answer 1

2Na+2H2O=2NaOH+H2
2NaOH+SO3=Na2SO4+H2O
Na2SO4+BaCl2=BaSO4↓+2NaCl
NaCl+AgNO3=NaNO3+AgCl↓


2Zn+O2 = 2ZnO
ZnO+2HCl = ZnCl2+H2O
ZnCl2+2KOH = Zn(OH)2↓+2KCl
Zn(OH)2+H2SO4 = ZnSO4+2H2O
ZnSO4+2NaOH = Na2SO4+Zn(OH)2↓

Answer 2

2Na+2H2O-->2NaOH+H2
2NaOH+H2SO4-->Na2SO4+2H2O
Na2SO4+BaCl2 -->BaSO4+2NaCL
NaCL+AgNO3-->NaNO3+AgCL

2Zn+O2-->2ZnO
ZnO+2HCL-->ZnCL2+H2O
ZnCL2+2NaOH-->Zn(OH)2+2NaCL
Zn(OH)2+H2SO4-->ZnSO4+2H2O
ZnSO4+2KOH-->K2SO4+Zn(OH)2
