Enter a chemical equation to balance:

Error: expresion "" is not a valid reaction
"=" symbol must be present in the equation between the reagents and the productsInstructions and examples below may help to solve this problem

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.

Examples of chemical equations to balance:

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.
