Which of the following is a NOT mechanism by which the biofuels are made? a. by reacting animal fat or vegetable oil with waterb
. by fermenting sugar components of starchy cropsc. by reacting animal fat or vegetable oil with alcohold. by treating animal fat or vegetable oil with hydrogen
A. by reacting animal fat or vegetable oil with water.
D. by treating animal fat or vegetable oil with hydrogen
Explanation:
Water is insoluble in animal fat or vegetable oil so it makes a layer on the surface of oil. When animal fat or vegetable oil react with hydrogen, it produces solid oil called ghee not biofuels. Biofuel is produced when animal fat or vegetable oil react with alcohol.
I believe the correct answer would be B. Semipermeable means that it allows certain substances to pass through, and certain other ones to not pass through. So given all of your options, I would say that B makes the most sense. Hope this helped!
