Reaction stoichiometry Limiting reagent Compound Coefficient Molar Mass Moles Weight FeCl3 1 162.204 KOH 3 56.10564 KCl 3 74.5513 Fe(OH)3 1 106.86702

Units: molar mass – g/mol, weight – g.Please tell about this free chemistry software to your friends!Direct link to this balanced equation: 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 e To 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 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. The limiting reagent row will be highlighted in pink.Examples of complete chemical equations to balance: Examples of the chemical equations reagents (a complete equation will be suggested): Give us feedback about your experience with chemical equation balancer.
