Iron pyrite is sometimes known as "fool's gold." If you had a yellow mineral, what would be one test you could use to see if it were real gold or iron pyrite? Explain how this test would differentiate between the two minerals? The test I would use is…

This test would differentiate between the two minerals because…

The most distinct difference between gold and pyrite is in their hardness. Gold is one of the most malleable and ductile metals on earth. The mineral can take any shape when flattened and is easily scratched with a pocket knife.

Explanation: so you could say " the test i would use is testing the hardness because pyrite is a lot harder than gold which can be easily bent where pyrite is harder than glass or most metals so i could tell by the hardness"

i believe the answer would be b. hope it : )
