3 Se + 3 H2O = 2 H2Se + H2SeO3
CaCl2 + H2O = CaCl2H2O =>
CaCl2 + H2O = CaCl2H2O
Mn + PbO2 = MnO + Pb =>
2 Mn + PbO2 = 2 MnO + Pb
BaSO4 + C8H18 = BaS + CO2 + H2O =>
25 BaSO4 + 4 C8H18 = 25 BaS + 32 CO2 + 36 H2O
C8H18 + O2 = CO2 + H2O =>
2 C8H18 + 25 O2 = 16 CO2 + 18 H2O
MgS + Li2CrO4 = MgCrO4 + Li2S =>
MgS + Li2CrO4 = MgCrO4 + Li2S
BF3 + Li2SO3 = B2(SO3)3 + LiF =>
2 BF3 + 3 Li2SO3 = B2(SO3)3 + 6 LiF
N2 + H2O + O = NH4NO3 =>
N2 + 2 H2O + O = NH4NO3
CrCl2 + K2Cr2O7 + HCl = CrCl3 + KCrO2 + H2O =>
6 CrCl2 + K2Cr2O7 + 6 HCl = 6 CrCl3 + 2 KCrO2 + 3 H2O
