What minerals scratch calcite?
Any mineral with a Mohs hardness of 3 or above. Diamond, for instance.
What minerals can be scratched with a knife?
Minerals that have a hardness less than that of a knife blade (5.5 on the Mohs scale) can be scratched with a knife. These minerals include gypsum, calcite, and talc.
What are the ten minerals of themohs scale?
The basic Moh's hardness scale consists of: 1. Talc (softest) 2. Gypsum 3. Calcite 4. Fluorite 5. Apatite 6. Feldspar 7. Quartz 8. Topaz 9. Corundum 10. Diamond (hardest)
How is mica and calcite be alike and how can they be different?
Mica and calcite are both minerals commonly found in Earth's crust. They both have distinct cleavage patterns, with mica typically having perfect basal cleavage and calcite having rhombohedral cleavage. However, they differ in chemical composition, as mica is a silicate mineral while calcite is a carbonate mineral. Additionally, mica displays a pearly luster and tends to be softer than calcite, which has a vitreous luster and can scratch glass.
What is the color of the mineral apatite?
the colors of apatite are green, yellow, blue, redish-brown and purple
Can Apatite can scratch calcite?
True
Which mineral on Mohs Hardness Scale will scratch calcite but will not scratch apatite?
Fluorite, which has a hardness of 4 on the Mohs Hardness Scale, can scratch calcite (hardness 3) but will not scratch apatite (hardness 5). Thus, fluorite fits the criteria of being able to scratch calcite while not being able to scratch apatite.
Is this statement true or false that apatite can scratch calcite?
Yes.Apatite - Ca5(PO4)3OH - has a Mohs hardness of 5.Calcite - CaCO3 - has a Mohs hardness of 5.
Which mineral will not scratch quartz topaz calcite or corundum?
apatite will not scratch quartz topaz calcite or corundum
Is apatite can scratch calcite true or false and because?
True, apatite can scratch calcite. This is because apatite has a higher hardness on the Mohs scale, rated at 5, while calcite is rated at 3. The hardness scale measures a mineral's ability to scratch another, so a mineral with a higher rating can scratch one with a lower rating.
Which mineral would scratch calcite but not apatite?
Fluorite would be able to scratch calcite but not apatite, as fluorite has a higher hardness than calcite but a lower hardness than apatite on the Mohs scale.
What mineral scratches calcite but it scratched by apatite?
The mineral that scratches calcite but is scratched by apatite is fluorite. Fluorite has a hardness of 4 on the Mohs scale, which allows it to scratch calcite (hardness 3), while apatite has a hardness of 5 and can scratch fluorite. Thus, the relationship between these minerals aligns with their respective positions on the Mohs hardness scale.
Can appetite scratch calcite?
No, appetite (also known as apatite) is not hard enough to scratch calcite. Calcite is a mineral that is harder than appetite on the Mohs scale of mineral hardness.
What minerals scratch calcite?
Any mineral with a Mohs hardness of 3 or above. Diamond, for instance.
Which object can scratch apatite but not feldspar?
Diamond can scratch apatite but not feldspar. This is due to the difference in hardness between the two minerals, with diamond being the hardest natural substance on the Mohs scale at 10, while apatite is around 5 and feldspar is around 6-6.5.
Can fluorite scratch apatite?
Yes, fluorite can scratch apatite. Fluorite is harder than apatite on the Mohs scale, which means it has the ability to scratch apatite.
Which minerals can scratch apatite?
Minerals that can scratch apatite include fluorite, quartz, topaz, and corundum. These minerals have a higher hardness level than apatite on the Mohs scale, which allows them to scratch apatite.
