Any mineral with a Mohs hardness of 3 or above. Diamond, for instance.
What else can I help you with?
Can a fingernail scratch some minerals?
Yes. But only soft ones such as talc (solid form of chalk and baby powder). Generally only minerals below 2 on the hardness scale.
Which object can scratch calcite but not apatite?
On the Mohs mineral hardness scale, calcite is about a 3, and apatite is about a 5. So, whatever is at a hardness of 4 will scratch a 3 but not a 5. That mineral is fluorite.
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.
The mineral which effervesces in the acid you use in lab is?
Minerals with the calcium carbonate compound show effervescence. Calcite is the most common carbonate mineral.
Is calcite gold?
No. Calcite is another name for calcium carbonate. CaCO3
What minerals can scratch a penny?
calcite
Can calcite scratch other minerals if so which one?
No.because calcite is softer then feldspar
What minerals can steel file scratch?
A steel file can scratch minerals with a hardness of 6.5 or lower on the Mohs scale. This includes minerals such as gypsum, calcite, and fluorite.
Which mineral is hard enough to scratch calcite but is not hard enough to scratch amphibole?
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.
Which mineral would a penny scratch?
A penny would scratch minerals with a lower hardness rating such as calcite, gypsum, or talc. Minerals like quartz or topaz would not be scratched by a penny because they are harder than the metal in a penny.
What mineral can scratch talc but is not scratched by calcite?
Diamond can scratch talc but is not scratched by calcite. Diamond is the hardest mineral on the Mohs scale, making it capable of scratching minerals with a lower hardness, like talc.
What minerals can a steel knife scratch?
A steel knife can scratch minerals with a hardness lower than that of steel, such as gypsum, calcite, fluorite, and talc. Minerals like quartz, topaz, and corundum are harder than steel and cannot be easily scratched by a steel knife.
Can a paperclip scratch calcite?
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.
What mineral that can scratch gypsum but cant scratch calcite?
Between 2 and 3 because its hard enough gypsum but it can not scratch calcite because calcite is harder
Which material would scratch the other quartz or calcite?
Quartz, with a hardness of 7, will scratch calcite, with a hardness of 3.
Which mineral will not scratch quartz topaz calcite or corundum?
apatite will not scratch quartz topaz calcite or corundum
Can calcite scratch feldspar?
no
