Instructions on balancing chemical equations:
- Enter an equation of a chemical reaction and click 'Balance'. 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 PhC2H5 + O2 = PhOH + CO2 + H2O will
- Compound 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. The limiting reagent row will be highlighted in pink.
