PbCrO4 + 2 NaOH = Pb(OH)2 + Na2CrO4
Sn + H2SO4 = SnSO4 + SO2 + H2O =>
Sn + 2 H2SO4 = SnSO4 + SO2 + 2 H2O
PbCrO4 + NaOH = Na2PbO2 + Na2CrO4 + H2O =>
PbCrO4 + 4 NaOH = Na2PbO2 + Na2CrO4 + 2 H2O
PbCrO4 + NaOH = Na2CrO4 + Pb2CrO5 + H2O =>
2 PbCrO4 + 2 NaOH = Na2CrO4 + Pb2CrO5 + H2O
HNO3 + Mn(OH)2 = HOH + (NO3)2Mn =>
2 HNO3 + Mn(OH)2 = 2 HOH + (NO3)2Mn
Ge + O2 = GeO =>
2 Ge + O2 = 2 GeO
NiCO3(s) + Fe(s) = FeCO3 + Ni =>
NiCO3(s) + Fe(s) = FeCO3 + Ni
Sn + H2SO4 = Sn(SO4)2 + H2 =>
Sn + 2 H2SO4 = Sn(SO4)2 + 2 H2
