Chemical Equation Balancer Cu2S*FeS2 + HNO3 = Cu(NO3)2 + Fe(NO3)3 + H2SO4 + N2O + H2O

Balanced Chemical Equation

8Cu2S·FeS2 + 106HNO3 = 16Cu(NO3)2 + 8Fe(NO3)3 + 24H2SO4 + 25N2O + 29H2O


To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above.

  • Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.
  • Ionic charges are not yet supported and will be ignored.
  • Replace immutable groups in compounds to avoid ambiguity. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will.
  • Compound states [like (s) (aq) or (g)] are not required.
  • You can use parenthesis () or brackets [].
