CuCO3*Cu(OH)2 = 2 CuO(s) + H2O + CO2
C4H6O5 + Mg(OH)2 = MgC4H4O5 + H2O =>
C4H6O5 + Mg(OH)2 = MgC4H4O5 + 2 H2O
SiO2 + NaHCO3 = SiHCO3 + NaO2 =>
SiO2 + NaHCO3 = SiHCO3 + NaO2
Na(s) + Br(s) = NaBr(s) =>
Na(s) + Br(s) = NaBr(s)
NaCHO2 + H2O = NaOH + HCHO2 =>
NaCHO2 + H2O = NaOH + HCHO2
Fe2S3 + CuCl2 = FeCl3 + CuS =>
Fe2S3 + 3 CuCl2 = 2 FeCl3 + 3 CuS
ZnSO4 + HCl = ZnCl2 + H2SO4 =>
ZnSO4 + 2 HCl = ZnCl2 + H2SO4
Sn + Hg(NO3)2 = Hg + Sn(NO3) =>
2 Sn + Hg(NO3)2 = Hg + 2 Sn(NO3)
Ru{3+} + BrO{-} + H2O = RuO4 + Br{-} + H{+} =>
2 Ru{3+} + 5 BrO{-} + 3 H2O = 2 RuO4 + 5 Br{-} + 6 H{+}
BaSO4 + Ba = BaO + BaSO3 =>
BaSO4 + Ba = BaO + BaSO3
