Astudent 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

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.

if you look at the answer above mine you will see an answer. it is the correct one
