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.
