A blend of glucose, yeast and water was put into a test-tube. A balloon was fitted onto the open end of the test-tube. The apparatus was left at 30^{\circ}C for one hour. The diagram shows the apparatus. Which word equation can be used to explain the change in the balloon after one hour?
- Acarbon dioxide + water → glucose + oxygen
- Bglucose → alcohol + carbon dioxide
- Cglucose → carbon dioxide + water
- Dglucose → lactic acid
