C6H12O6 → 2C2H5OH + 2 CO2
a molecule of glucose is converted into 2 molecules of ethanol and 2 of carbon dioxide
This simple experiment shows how gas is released during fermentation. After some time the balloon fills with carbon dioxide. The water must be warm and sugar must be added. This is exactly what happens during bread and beer making.
