What is pink color nonmetalic and galssy luster softer than topaz quuartz scratches apatite harder than fluorite has clevage and is scratched by a steel file?
What is pink color nonmetalic and galssy luster softer than topaz quuartz scratches apatite harder than fluorite has clevage and is scratched by a steel file?
Can apatite scratch topaz?
No, apatite cannot scratch topaz. On the Mohs scale of mineral hardness, apatite has a hardness of 5, while topaz has a hardness of 8. This means that topaz is significantly harder than apatite and can easily scratch it.
What is the density of mineral apatite?
Its density is: 3.19
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.
What is a mineral scratch test?
In 1822 scientist Friedrich Mohs developed a scale to measure the hardness of minerals. A mineral will scratch other minerals softer than itself and will be scratched by minerals that are harder.
What is softer than quarts but harder than apatite?
Topaz is softer than quartz but harder than apatite on the Mohs scale of mineral hardness. It has a hardness of 8 on the scale, whereas quartz has a hardness of 7 and apatite has a hardness of 5.
What two minerals are harder than calcite but softer than quartz?
Fluorite and apatite are two minerals that are harder than calcite but softer than quartz on the Mohs scale of mineral hardness. They have hardness values of 4 (fluorite) and 5 (apatite) respectively, compared to 3 for calcite and 7 for quartz.
What is the mineral that can scratch fluorite but not quartz?
There are many, anything that has a hardness greater than 4 and less than 7, like Plagioclase. Just listing the ones on the Mohs scale, there's apatite and orthoclase.
On mohs' hardness scale what mineral is harder than quartz but harder than appetite?
If you mean isn't harder than quartz but harder than apatite ( you spelled it wrong), that would be Orthoclase Feldspar. Else the minerals that are harder than both apatite and quartz are topaz, corundum, and diamond (diamond being the hardest, well the hardest non synthetic mineral).
What two minerals are softer than apatite?
Talc and Gypsym
Is apatite a mineral?
Yes Apatite is a mineral.
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 has a hardness nearest to that of glass?
Glass has a hardness of 5.5 Minerals with hardness nearest to that of glass include apatite, which is slightly softer than glass with a hardness of 5.0, and orthoclase, which is slightly harder than glass with a hardness of 6.0.
What is pink color nonmetalic and galssy luster softer than topaz quuartz scratches apatite harder than fluorite has clevage and is scratched by a steel file?
What is pink color nonmetalic and galssy luster softer than topaz quuartz scratches apatite harder than fluorite has clevage and is scratched by a steel file?
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.
Are there any minerals softer than talc?
There are no other minerals that are softer than talc. On Moh's hardness scale, diamonds are the hardest mineral, and talc is the softest mineral in the world.
Which mineral on the mohs scale will scratch apatite?
Minerals that will scratch apatite must be more than a 5 on the Moh's hardness scale. So feldspar, quartz, topaz, corundum, and diamond will scratch apatite.
