The chemical equation that shows the chemical reaction needs to be balanced. A balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products
:Instructions on balancing chemical equations:
Enter an equation of a chemical reaction and click 'Balance'.
The answer will appear belowAlways 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 monoxideTo enter an electron into a chemical equation use {-} or eTo enter an ion specify charge after the compound in curly brackets: {+3} or {3+} or {3}.
Example: Fe{3+} + I{-} = Fe{2+} + I2Substitute immutable groups in chemical compounds to avoid ambiguity.
For instance equation C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced,
but PhC2H5 + O2 = PhOH + CO2 + H2O willCompound states [like (s) (aq) or (g)] are not required.If you do not know what products are enter reagents only and click 'Balance'. In many cases a complete equation will be suggested.Reaction stoichiometry could be computed for a balanced equation. Enter either the number of moles or weight for one of the compounds to compute the rest.Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents.
Examples of complete chemical equations to balance:Fe + Cl2 = FeCl3KMnO4 + HCl = KCl + MnCl2 + H2O + Cl2K4Fe(CN)6 + H2SO4 + H2O = K2SO4 + FeSO4 + (NH4)2SO4 + COC6H5COOH + O2 = CO2 + H2OK4Fe(CN)6 + KMnO4 + H2SO4 = KHSO4 + Fe2(SO4)3 + MnSO4 + HNO3 + CO2 + H2OCr2O7{-2} + H{+} + {-} = Cr{+3} + H2OS{-2} + I2 = I{-} + SPhCH3 + KMnO4 + H2SO4 = PhCOOH + K2SO4 + MnSO4 + H2OCuSO4*5H2O = CuSO4 + H2Ocalcium hydroxide + carbon dioxide = calcium carbonate + watersulfur + ozone = sulfur dioxide
