| Enter a chemical equation to balance: |
Instructions on balancing chemical equations:
- Enter an equation of a chemical reaction and press the 'Balance!' button. The answer will appear below
- Always use the upper case for the first character in the element name and the lower case for the second character.
Examples: Fe, Au, Co, Br, C, O, N, F. Compare: Co - cobalt and CO - carbon monoxide - To enter an electron into a chemical equation use {-} or e
- To enter an ion specify charge after the compound in curly brackets: {+3} or {3+} or {3}.
Example: Fe{3+}+I{-}=Fe{2+}+I2 - Substitute immutable groups in chemical compounds to avoid ambiguity.
For instance equation 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.
- Fe + Cl2 = FeCl3
- KMnO4 + HCl = KCl + MnCl2 + H2O + Cl2
- K4Fe(CN)6 + H2SO4 + H2O = K2SO4 + FeSO4 + (NH4)2SO4 + CO
- C6H5COOH + O2 = CO2 + H2O
- K4Fe(CN)6 + KMnO4 + H2SO4 = KHSO4 + Fe2(SO4)3 + MnSO4 + HNO3 + CO2 + H2O
- Cr2O7{-2} + H{+} + {-} = Cr{+3} + H2O
- S{-2} + I2 = I{-} + S
- PhCH3 + KMnO4 + H2SO4 = PhCOOH + K2SO4 + MnSO4 + H2O
- CuSO4*5H2O = CuSO4 + H2O

Hint: copy & paste one of examples of chemical equations to see how balancing works. |
