To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above.
- Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.
- Ionic charges are not yet supported and will be ignored.
- Replace immutable groups in compounds to avoid ambiguity. For example, 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.
- You can use parenthesis () or brackets [].

[external_link offset=2]Balance The Equation: NaOH + CO2 = Na2CO3 + H2O 1. Label Each Compound With a Variable aNaOH + bCO2 = cNa2CO3 + dH2O 2. Create a System of Equations, One Per Element Na: 1a + 0b = 2c + 0d O: 1a + 2b = 3c + 1d H: 1a + 0b = 0c + 2d C: 0a + 1b = 1c + 0d 3. Solve For All Variables a = 2 b = 1 c = 1 d = 1 4. Substitute and Verify Result 2NaOH + CO2 = Na2CO3 + H2O L R Na: 2 2 ✔️ O: 4 4 ✔️ H: 2 2 ✔️ C: 1 1 ✔️
