Which mineral will not scratch quartz topaz calcite or corundum?
apatite will not scratch quartz topaz calcite or corundum
What unknown mineral is found to scratch apatite and to be scratched by corundum?
The unknown mineral would be topaz. Topaz lies between apatite and corundum on the Mohs scale, making it capable of scratching apatite and being scratched by corundum.
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.
Which mineral can be scratched by a steel nail?
Calcite is a mineral that can be easily scratched by a steel nail due to its relatively low hardness compared to steel.
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.
If a mineral scratches calcite but is scratched by apatite what is the minerals hardness?
Somewhere between 3 and 5 on the Mohs scale of relative mineral hardness...
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.
What mineral can be scratched with a steel knife or window glass?
apatite with a steel knife feldspar with window glass
An unknown mineral scratches apatite and is scratched by corundum. What can you conclude about this mineral and hardness?
The unknown mineral has a hardness greater than that of apatite (which has a hardness of 5 on the Mohs scale) since it can scratch it. However, it has a hardness less than corundum (which has a hardness of 9) since it can be scratched by it. Therefore, we can conclude that the hardness of the unknown mineral is between 5 and 9 on the Mohs scale.
Can apatite be scratched by quartz?
Quartz is harder than apatite, quartz being a 7 on the Mohs mineral hardness scale and apatite being a 5.
Which mineral will not scratch quartz topaz calcite or corundum?
apatite will not scratch quartz topaz calcite or corundum
What unknown mineral is found to scratch apatite and to be scratched by corundum?
The unknown mineral would be topaz. Topaz lies between apatite and corundum on the Mohs scale, making it capable of scratching apatite and being scratched by 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.
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.
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.
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.
Which mineral can be scratched by a steel nail?
Calcite is a mineral that can be easily scratched by a steel nail due to its relatively low hardness compared to steel.
