Acetaminophen (generic name for Tylenol® ) consists of carbon, hydrogen, nitrogen, and oxygen atoms. A student in an organic chemistry laboratory prepares impure acetaminophen and dissolves it in hot water in order to purify it by recrystallization. No crystals form on cooling, and so the student pours out the solution and starts the experiment over. Have the carbon, hydrogen, nitrogen, and oxygen atoms of the acetaminophen been destroyed?
