How to balance it, step by step
- Count the atoms of each element on both sides, as written.
- Start with the biggest formula, C₆H₁₂O₆: put 1 in front of it.
- H: 12 on the left. Put 2 in front of C₂H₅OH (2 × 6 = 12).
- C: 6 on the left, 4 already on the right. Put 2 in front of CO₂ (2 × 1 = 2).
- Check: C 6 = 6, H 12 = 12, O 6 = 6. Balanced.
What happens
It is fermentation: yeast breaks glucose down without oxygen. Yeast breaks glucose down without oxygen into ethanol and carbon dioxide. This is how bread rises and how ethanol is made.
Fermentation of glucose: quick answers
What is the balanced equation for fermentation of glucose?
C₆H₁₂O₆(aq) → 2 C₂H₅OH(aq) + 2 CO₂(g). The coefficients are 1, 2 and 2. Each side then has 6 C, 12 H and 6 O.

How do you balance C₆H₁₂O₆ → C₂H₅OH + CO₂?
Start with the biggest formula, C₆H₁₂O₆: put 1 in front of it. H: 12 on the left. Put 2 in front of C₂H₅OH (2 × 6 = 12). C: 6 on the left, 4 already on the right. Put 2 in front of CO₂ (2 × 1 = 2). Never change a subscript, because that would change the substance.
