If a mineral can be scratched by a fingernail but not by a pocket knife what does that tell us about the mineral?
It would have a Mohs hardness somewhere between 2.5 and 5.5.
Describe how to find the hardness of unknown mineral?
Minerals are tested for hardness by performing a scratch test. The unknown mineral is scratched with another object that the hardness is known. For example, a unknown mineral may be scratched with a piece of metal to compare the resistance.
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 harness of a mineral if it scratches a penny but will not scratch glass?
Google "Mohs hardness scale". This is a relative hardness scale which compares one mineral's hardness to another. (It is between 3.5 and 5.5 on the Mohs hardness scale)
What is the relationship between bond strength and mineral hardness?
Bond strength is related to mineral hardness. Minerals with strong chemical bonds tend to have high hardness, while minerals with weaker bonds have lower hardness. This is because the strength of the bonds affects how easily the mineral can be scratched or deformed.
What is the most diagnostic physical property of a mineral?
The most diagnostic physical property of a mineral is its hardness, which is measured on the Mohs scale. Hardness indicates how resistant a mineral is to scratching and can help distinguish between different minerals. For example, talc is the softest mineral on the scale (1), while diamond is the hardest (10). Other important properties include color, luster, and streak, but hardness is often the most reliable for identification.

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 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 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...
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 the hardness of a mineral if it scratches a penny but will not scratch glass?
Between 3.5 and 5.5 on the Mohs scale of mineral hardness.
What is the hardnessof a mineral that scratches the gypsum but can't scratch fluorite?
Between 2 and 4. Calcite, which has a hardness of 3, is one example.
Is a Gray mineral harder than a white mineral?
No, there is no correlation between color and hardness in minerals.
