Fermentation of grapes is considered as a chemical reaction as it is a

a. chemical change
b. sugar in grapes converts into alcohol
c. irreversible change
d. all of the above​

Answer 1

Answer:

all of the above

Explanation:

as the sugars changes into alcohol which is a chemical process and is irreversible as we can't get grapes back from the alcohol ( grape wine)

Answer 2

Fermentation of grapes is considered as a chemical reaction as it is a chemical change, sugar in grapes converts into alcohol and an irreversible change.

• Yeasts are used for the production of beverages that contain alcohol.
• They produce ethanol from the sugars present in the grapes by the process of alcoholic fermentation.
• This process is a chemical process and is hence, irreversible.
• Irreversible changes occur only in one direction since the formation of a new substance takes place.
• So, all the above options are correct.
