Na 2+H2=NH3
Fe11+HCL=........+H2
Zn(OH)2+HNO3=...................+H2O
Fe(OH)3=Fe2O3+H2O
PbO2_PbO+O2
AlCl3+H2SO4_Al2(SO4)3+HCL

Answer 1

N2 + 3 H2 =  2 NH3

Fe + 2 HCl = FeCl2 +H2

Zn(OH)2 + 2 HNo3 = Zn(No3)2 + 2 H2O

2 Fe(OH)3 =  Fe2O3 + 3 H2O

2 PbO2 = 2 PbO + O2

2 AlCl3 + 3 H2SO4 = Al2(SO4)3 + 6 HCl
