Question

Yeast, warm water and substance Z were put into a test tube. The apparatus was then set up as shown. After a while, the lime water began to go cloudy. What is substance Z?

Answer 1

Step-by-step explanation:

Substance Z is likely an organic compound that is capable of undergoing fermentation. Fermentation is the process by which yeast breaks down carbohydrates and produces ethanol and carbon dioxide. The carbon dioxide produced during the fermentation process causes the lime water to go cloudy.
