2 NaBH4 + H2SO4 = B2H6 + 2 H2 + Na2SO4
WO3 + H2 = W + H2O =>
WO3 + 3 H2 = W + 3 H2O
(NH4)2Cr2O7 = N2 + H2O + Cr2O3 =>
(NH4)2Cr2O7 = N2 + 4 H2O + Cr2O3
Ca(NO3) + Na(PO4) = Ca(PO4) + Na(NO3) =>
Ca(NO3) + Na(PO4) = Ca(PO4) + Na(NO3)
Ca(NO3) + Na(PO4) = Ca(PO4) + Na(NO3) =>
Ca(NO3) + Na(PO4) = Ca(PO4) + Na(NO3)
C6H14 + O2 = H2O + CO2 =>
2 C6H14 + 19 O2 = 14 H2O + 12 CO2
C8H18 + O2 = H2O + CO2 =>
2 C8H18 + 25 O2 = 18 H2O + 16 CO2
Cu + HNO3 = CuN2O6 + H2O + NO =>
3 Cu + 8 HNO3 = 3 CuN2O6 + 4 H2O + 2 NO
SO2 + O = SO3 =>
SO2 + O = SO3
S + CO2 = SO2 + C =>
S + CO2 = SO2 + C
