What mineral can scratch fluorite, galena, and pyroxene?

Question:

Which mineral will scratch fluorite, galena, and pyroxene?

Answer:

Quartz is a mineral that can scratch fluorite, galena, and pyroxene.

Explanation:

The mineral that can scratch fluorite, galena, and pyroxene is quartz. Quartz is a mineral that has a hardness of 7 on the Mohs scale. The Mohs scale is a scale that ranks minerals based on their hardness, with 1 being the softest and 10 being the hardest. Fluorite has a hardness of 4, galena has a hardness of 2.5, and pyroxene has a hardness of 5-6. Since quartz is harder than all three of these minerals, it can scratch them.

For example, if you were to try to scratch fluorite with quartz, the quartz would leave a mark on the fluorite, but the fluorite would not be able to scratch the quartz.
