Chemical equation balancer

A chemical equation solver that balances the lot!

 

It can solve ..

  1. Complete neutral species and ionic equations.
  2. Half equations in acid or alkali solutions.
  3. Equations with more than one solution.
  4. Equations with non-stoichiometric chemical formula. eg. K3.99Fe(CN)6 and NaHBr1.997
  5. Complex chemical equations with multiple terms and brackets. eg. (NH4)3[P(Mo3O10)4]

 

Solve the following chemical equations. Just copy and paste then submit.

You may also include standard physical states, (s), (l), (g) & (aq) or leave them out.

  2. CH4(g) + O2(g) = C(s) + CO(g) + CO2(g) + H2O(l)
  3. C8H18(l) + O2(g) → H2O(l)  + CO2(g) + CO(g) + C(s)  The combustion of octane

 

C. Chemical equations involving ionic charges.

You may enclose charges in {} eg. {2+}. This ensures the numeric value is parsed as a charge.

  1. ClO2{+}(aq) + H3O+(aq) = Cl2(g) + H2O(l) + ClO3-(aq) + ClO2(aq)
  2. Bi3+(aq) + HSnO2-(aq) + OH-(aq) = Bi(s) + H2O(l) + SnO32-(aq)
  3. CH3CH2OH(aq) + Cr2O72-(aq) + H+(aq) + CH3COOH(aq) + Cr3+(aq) + H2O(l)
  4. I- + I2 + Mn2+ + MnO4- + H+ + H2O   Note: If reactants and products are mixed then species are correctly re-sorted.
  5. Cl2(g) + Cl-(aq) + Fe2+(aq) + Fe3+(aq)
  6. Mn2+ + BiO3- + H+ -> MnO4- + Bi3+ + H2O
  7. NpO2{2+} + NpO2(OH)H2C2O4{+} = NpO2{+} + CO2 + H+ + O2
  8. H3PO4 + (NH4)6Mo7O24 + H+ → (NH4)3PO4(MoO3)12 + NH4+ + H2O

 

D. Chemical half equations. You may enclose charges in {} eg. {+} to make sure the numeric value is parsed as a charge.
