What is the hardness of an unknown mineral that scratches glass but will not scratch quartz?
The unknown mineral would have a hardness greater than 5.5 (the hardness of glass) but less than 7 (the hardness of quartz). Based on the Mohs Hardness Scale, the unknown mineral would likely have a hardness between 6 and 7.
What kind of mineral can scratch quartz but not diamond?
According to the Mohs scale of hardness, Diamond has a hardness of 10 and Quartz has a hardness of 7. Any mineral with a hardness greater than 7 can scratch quartz and diamond can scratch any mineral with a hardness less than 10. Corundum (hardness of 9) and Topaz (hardness of 8) are two examples of minerals that can scratch quartz but not diamond.
Describe what would happen if you rubbed a mineral with a mohs hardness value of 7 against a mineral with a value of 5?
The mineral with a Mohs hardness value of 7 (such as quartz) would scratch the mineral with a value of 5 (such as apatite). This is because a mineral can scratch any other mineral with a lower Mohs hardness value.
What is the hardness of pegmatite?
The hardness of pegmatite can vary depending on its mineral composition, but it typically falls between 6 to 7 on the Mohs scale of mineral hardness. This means that pegmatite is harder than steel but softer than quartz.
What will if you rub a mineral with the hardness of 3 with a mineral with a hardness of 9?
The mineral with hardness 3 will get scratched.
If an unknown has hardness between 5 and 9 what could you do to the mineral to find out mor about its hardness?
To determine the hardness of a mineral with a hardness between 5 and 9, you can perform a scratch test using reference minerals from the Mohs scale. Start by testing it against minerals with known hardness values, such as quartz (hardness 7) and topaz (hardness 8). If the unknown scratches quartz but is scratched by topaz, its hardness is between 7 and 8. This method will help narrow down the mineral's hardness more precisely.
What is the hardness of a steel nail on the Mohs scale?
The hardness of a steel nail is about 4.5 (About the same hardness of the mineral Fluorite.)
An unknown mineral scratches glass but will scratch quartz What measure om the mohs scale shows its hardness?
The unknown mineral is not a mineral, or the pieces being scratched or doing the scratching are not freshly fractured or cleaved surfaces.
What is the hardness of flint?
Flint is a type of Quartz, and Quartz is a 7 on the Mohs Hardness Scale
What mineral has the greatest hardness?
The mineral with the greatest hardness is the diamond.
If a mineral is a 6 on the mohs scale what can it be scracted by?
A mineral with a hardness of 6 on the Mohs scale can be scratched by anything harder than a 6, such as minerals with a hardness of 7 or higher. It will not be scratched by minerals with a hardness of 5 or lower.
