HCHO + 4AgNo3 + 4NH3 + H2O → 4Ag + 4NH4No3 + CO2
Instructions
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: HCHO + AgNo3 + NH3 + H2O = Ag + NH4No3 + CO2 1. Label Each Compound With a Variable aHCHO + bAgNo3 + cNH3 + dH2O = fAg + gNH4No3 + hCO2 2. Create a System of Equations, One Per Element H: 2a + 0b + 3c + 2d = 0f + 4g + 0h C: 1a + 0b + 0c + 0d = 0f + 0g + 1h O: 1a + 0b + 0c + 1d = 0f + 0g + 2h Ag: 0a + 1b + 0c + 0d = 1f + 0g + 0h No: 0a + 3b + 0c + 0d = 0f + 3g + 0h N: 0a + 0b + 1c + 0d = 0f + 1g + 0h 3. Solve For All Variables a = 1 b = 4 c = 4 d = 1 f = 4 g = 4 h = 1 4. Substitute and Verify Result HCHO + 4AgNo3 + 4NH3 + H2O = 4Ag + 4NH4No3 + CO2 L R H: 16 16 ✔️ C: 1 1 ✔️ O: 2 2 ✔️ Ag: 4 4 ✔️ No: 12 12 ✔️ N: 4 4 ✔️
