Answer

Brief Explanations:

A chemical change results in the formation of a new substance. In option B, hematite particles rearrange to form a new substance, which is a chemical change. Options A, C, D, and E describe physical changes like separation, mixing, change in vibration due to heat, and change in location respectively, without forming new substances.

Answer:

B. The hematite particles rearrange to form a new substance.
