(6) each student in ms. hensons science class was given a beaker containing several substances that had been stirred thoroughly. a student must classify the contents of his beaker as either a compound or a mixture. which of the following would indicate that the beaker contains a mixture? a) the original substances had different densities. b) the contents of the beaker reacted to form a new substance. c) the original substances had a greater mass than the contents of the beaker. d) the contents of the beaker can be easily separated into the original substances.
Answer
Brief Explanations:
A mixture is composed of two or more substances that are physically combined and can be separated by physical means. Option D indicates that the contents can be easily separated into the original substances, which is a key characteristic of a mixture. Option A about different densities doesn't necessarily mean it's a mixture. Option B describes a chemical reaction forming a new substance, which is a compound - not a mixture. Option C about mass comparison is not relevant to the definition of a mixture.
Answer:
D. The contents of the beaker can be easily separated into the original substances.
