2 ZnS + 3 O2 = 2 ZnO + 2 SO2
FeS + NO2{-} + H{+} = Fe{3+} + SO3{2-} + H2O + NO =>
FeS + 7 NO2{-} + 8 H{+} = Fe{3+} + SO3{2-} + 4 H2O + 7 NO
CuSO4 + NaOH = Cu(OH)2 + Na2SO4 =>
CuSO4 + 2 NaOH = Cu(OH)2 + Na2SO4
Ca3(PPO4)2 + SiO2 + C = CaSiO3 + P4 + CO =>
Ca3(PPO4)2 + 3 SiO2 + 5 C = 3 CaSiO3 + P4 + 5 CO
Ag + FeCl2 = AgCl + Fe =>
2 Ag + FeCl2 = 2 AgCl + Fe
CuO + HCl = CuCl2 + H2O =>
CuO + 2 HCl = CuCl2 + H2O
