The most likely reason for the observation by the student is the combined substances chemically reacted; the correct option is C.

What are chemical reactions?

Chemical reactions are reactions that involve changes in the chemical properties of the substance as well as changes in the chemical composition and structure of the substances involved.

There are several types of chemical reactions and they include:

  • precipitation reactions
  • combustion reaction
  • redox reactions
  • neutralization reactions
  • catalytic reactions

In a precipitation reaction, an insoluble substance is obtained when two solutions are mixed together. The insoluble substance obtained is called a precipitate.

Precipitation reactions are also known as a double replacement or double displacement reactions.

The given reaction by a student who observed a decrease in temperature when two substances were combined and a milky substance formed and sank to the bottom of the flask is an example of a precipitation reaction.
