4 FeS2 + 11 O2 = 2 Fe2O3 + 8 SO2
HBr + NH3 = NH4 + Br =>
HBr + NH3 = NH4 + Br
C5H10Br2 + Zn = C5H10Br2Zn =>
C5H10Br2 + Zn = C5H10Br2Zn
C2H6 + O2 = CO2 + HO = O =>
C2H6 + 5 O2 = 2 CO2 + 6 HO
Cu2O + H2 = Cu + H2O =>
Cu2O + H2 = 2 Cu + H2O
Na2CO3 + HNO3 = NaNO3 + CO2 + H2O =>
Na2CO3 + 2 HNO3 = 2 NaNO3 + CO2 + H2O
Na2[Cr(OH)4] + H2SO4 = Cr(OH)2 + Na2SO4 + H2O =>
Na2[Cr(OH)4] + H2SO4 = Cr(OH)2 + Na2SO4 + 2 H2O
K2S + Cu(NO3)2 = KNO3 + CuS =>
K2S + Cu(NO3)2 = 2 KNO3 + CuS
