No, a paperclip is not hard enough to scratch calcite. Calcite is a mineral with a hardness of 3 on the Mohs scale, while a paperclip is softer and would not be able to scratch calcite.
apatite will not scratch quartz topaz calcite or corundum
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.
No.because calcite is softer then feldspar
Using the Mohs Mineral Hardness scale, calcite has a hardness of 3. Hence anything with a hardness of 3 or above can scratch calcite (i.e...quartz and fluorite).
Yes
Between 2 and 3 because its hard enough gypsum but it can not scratch calcite because calcite is harder
calcite
Quartz, with a hardness of 7, will scratch calcite, with a hardness of 3.
apatite will not scratch quartz topaz calcite or corundum
no
calcite is a 3 on the Mohs scale of Hardness and can scratch anything that's under it. just that simple
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.
Yes.Apatite - Ca5(PO4)3OH - has a Mohs hardness of 5.Calcite - CaCO3 - has a Mohs hardness of 5.
True
No.because calcite is softer then feldspar
Quartz is hard enough to scratch calcite, as it has a higher hardness rating on the Mohs scale. However, quartz is not hard enough to scratch amphibole minerals, which are generally harder than 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.
