Answer

Brief Explanations:

Mineral identification uses multiple properties. Hardness is one, but color can vary due to impurities. So same - hardness minerals may or may not be the same. Carbon is common in living things and not concentrated in most rocks as it is mainly involved in organic compounds and cycles rather than rock - forming processes.

Answer:

First question: they may or may not be the same mineral, because hardness is only one indicator of mineral identification Second question: carbon
