which are of solvent?
(C) If all the bigger molecules in A are

Answer 1

Answer:

A change in color is also another characteristic of a chemical reaction taking place. For example, if one were to observe the rusting of metal over time, one would realized that the metal has changed color and turned orange. This change in color is evidence of a chemical reaction.

BUT HERE

Mixing some colors with water is a physical change.

It is a solution—a homogeneous mixture. Explanation: The water and colors are mixed together, the liquid looks the same throughout.
