A student performs the following experiment. step 1: she pours a colorless solution into a beaker that contains another colorless liquid. yellow particles appear in the liquid. step 2: she lets the yellow particles settle in the beaker and then separates the colorless liquid by decantation. what has most likely occurred in the beaker? a chemical change in step 1 and a physical change in step 2 a physical change in step 1 and a chemical change in step 2 chemical changes in both step 1 and step 2 physical changes in both step 1 and step 2

Base on the steps and the question which ask to choose among the choices that states what is occured in the beaker and base on observation, the answer would be "a physical change in both step 1 and step 2", I hope you are satisfied with my answer and feel free to ask for more

Answer : Option A) Chemical change in step 1 and physical change in step 2.

Explanation : When the student poured the colorless solution into another liquid there was a chemical reaction that took place and produced a precipitate which was yellow in color. Later on, in step 2 when these precipitate particles settled it left a colorless liquid at the top, so, this was a physical change no new substance was produced just a physical process had taken place, and through decantation it was removed.
