A magnet was placed near a pile that contained both iron and sulfur. The magnet was moved gradually closer to the pile. As it neared the pile, the magnet started attracting small pieces of iron from the pile.
What best describes?
A. Solution or iron and sulfer can be separated by magnetism
B. Heterogeneous mixutre or iron and sulfur can be separated by magnetism.
C. Compound of iron and sulfur that can be separated by magnetism
D. Suspension of sulfur in iron that can be separated by magnetism
I think it is B
You are correct, the best description for the scenario you have provided is option B - "Heterogeneous mixture of iron and sulfur that can be separated by magnetism."
To arrive at this conclusion, you can analyze the provided information. The fact that the magnet started attracting small pieces of iron from the pile indicates that the iron and sulfur are not chemically bonded together. Instead, they are mixed together in some form.
The term "heterogeneous mixture" refers to a mixture that is not uniform throughout. In this case, the iron and sulfur are not evenly distributed but exist as separate particles within the pile. The magnetism exhibited by the iron allows it to be attracted to the magnet, while the sulfur remains unaffected.
Furthermore, the ability to separate the mixture using magnetism supports the idea that it is a heterogeneous mixture. By gradually moving the magnet closer to the pile, the iron particles are selectively attracted to the magnet while the sulfur particles are left behind.
Thus, option B is the most appropriate description for the given scenario.
