3 MnO2 + 4 Al = 2 Al2O3 + 3 Mn
OH + HNO3 = H3O + NO3 =>
OH + 2 HNO3 = H3O + 2 NO3
U + H = H2U =>
U + 2 H = H2U
C3H7Br + Br2 = C3H6Br2 + HBr =>
C3H7Br + Br2 = C3H6Br2 + HBr
MnO2 + Al = Al2O3 + Mn =>
3 MnO2 + 4 Al = 2 Al2O3 + 3 Mn
(NH4)2CU(SO4)2 + KI = (NH4)2CU(I)4 + K2SO4 =>
(NH4)2CU(SO4)2 + 4 KI = (NH4)2CU(I)4 + 2 K2SO4
HNO2 + Fe = Fe(HNO2)3 =>
3 HNO2 + Fe = Fe(HNO2)3
