Question

Mary Sue is making caramel ice cream. In the first part of the process, she combines a cup of sugar and a cup of water in a saucepan. She cooks the mixture over medium heat until the sugar melts and browns to a light amber color. Then she adds the same amount of water to the mixture along with a cup and a half of cream and milk.
Which part of the preparation indicated a chemical change? Question 15 options:
A mixing the sugar with water
B adding cream and milk to the mixture
C sugar changes from white to a light amber color
D melting the sugar

Answer 1

Answer:

In the whole process of making caramel ice cream by Marrie Sue the chemical reaction occurs when sugar changes from white to light amber color after it melts.

The difference in color indicates that diacetyl, a volatile chemical compound has been released giving the sugar a caramel flavor.

The other reactions in the process of ice cream makers are not the chemical change.
