Answer

Brief Explanations:

In step 1, a new substance (yellow particles) is formed when two color - less liquids are mixed, which indicates a chemical change. In step 2, separating the liquid by decantation is a physical process as it only changes the physical state of separation of substances without changing their chemical composition.

Answer:

A. a chemical change in step 1 and a physical change in step 2
