What could have gone wrong in the separation and purification process to result in the disparity from the observed and expected yields? Select all that apply A) Both the benzoic acid and sand may have been wet before the student recorded the masses, hence the increase in expected masses. B) The student may have filtered the benzoic acid while cold. Hence the sand could have been contaminated with benzoic acid and resulted in a higher mass for sand. C) The sand may have dissolved in the hot water along with the benzoic acid, hence, the recorded mass for benzoic acid was more.

A) Both the benzoic acid and sand may have been wet before the student recorded the masses, hence the increase in expected masses.
B) The student may have filtered the benzoic acid while cold. Hence the sand could have been contaminated with benzoic acid and resulted in a higher mass for sand.
C) The sand may have dissolved in the hot water along with the benzoic acid, hence, the recorded mass for benzoic acid was more.
D)The benzoic acid may have been cooled down too quickly on ice thereby allowing other soluble impurities to crystallize with benzoic acid causing the increase in the expected mass
