Zn + KOH → K2ZnO2 +H2
FeO2 + CO → Fe + CO2
PbO + NH3 → Pb + H2O + N2
Pb3O4 → PbO+ O2
PbS + O2 → PbO + SO2
S +H2SO4 + SO2 + H2O
S + HNO3 → H2SO4 + NO2 + H2O
MnO2 + HCl → MnCI2 + H20 + CI2
C + H2SO4 → CO2 + H2O+SO2
KOH + Cl2 → KCI + KCIO + H2O
NO2 +H2O → HNO2 + HNO3
Pb3O4 + HCl → PbCl2 + H2O + CI2
H2O + Cl2 → HCI +02
NaHCO3 → Na2CO3 + H20 + CO2
HNO3 +H2S → NO2 +H20 + S
P + HNO3 → NO2 +H20 + H3PO4
Zn + HNO3 → Zn(NO3)2 + H2O + NO2

Answer:C. Zn+2KOH=K2ZnO2+H2
d. Fe2O3 +3CO → 2Fe + 3CO2
(e) 3PbO + 2NH3→3 Pb +3 H2O + N2
(f) 2Pb3O4-->6PbO + O2
(g/) 2PbS+3O2--->2PbO + 2SO2
(h)2 S+H2SO4--->2 SO2+ H2O
(i) S + 4HNO3 → H2SO4+ 4NO2 + H2O
(j) MnO2 +4 HCl → MnCl2 + 2H2O + CI2
(k) C + 2H2SO4---->CO2+2H20 +2SO2
(l) 2KOH + Cl2 → KCl + KCIO + H2O
