Equation is already balanced.
To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above.[external_link_head][external_link offset=1]
- 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 .

Balance The Equation: C2H2 + Br2 = C2H2Br2 1. Label Each Compound With a Variable aC2H2 + bBr2 = cC2H2Br2 2. Create a System of Equations, One Per Element C: 2a + 0b = 2c H: 2a + 0b = 2c Br: 0a + 2b = 2c 3. Solve For All Variables a = 1 b = 1 c = 1 4. Substitute and Verify Result C2H2 + Br2 = C2H2Br2 L R C: 2 2 ✔️ H: 2 2 ✔️ Br: 2 2 ✔️
