recycling plant needs to separate two types of
plastic: ABS, d = 1.15 g/mL and PET, d = 1.35 g/mL. Would a solution of NaCI with a density of
1.05 g/mL be able to separate them? A. No, the two plastics will not be separated because both types would sink when added to
the solution of NaCI. B. No, the two plastics will not be separated because both types would float when added to
the solution of NaCI. C. Yes, the two plastics will be separated because ABS would sink and PET would float when
added to the solution of NaCI. D. Yes, the two plastics will be separated because ABS would float and PET would sink when
added to the solution of NaCI.
