What mineral can scratch itself but no other mineral can scratch it?
A diamond is the only material that cannot be scratched by any other than itself.
Is the following question true or false a mineral can scratch any mineral harder than itself?
True. In general, a mineral can scratch any mineral that is softer than itself according to Mohs Scale of Mineral Hardness. This means that a mineral with a higher number on the scale can scratch a mineral with a lower number.
If a mineral can scratch a penny what number is it on Mohs Scale?
Most of the time, no. But there are some minerals, such as kyanite, that have more than one hardness in an individual crystal. But this is an exception to the Mohs scale of mineral hardness, which is based on the premise that a mineral of a lower number cannot scratch a mineral of a higher (harder) number.
Can talc scratch over minerals?
Talc is the softest mineral on the Mohs scale with a hardness of 1, so it can be easily scratched by harder minerals. Talc can scratch over minerals with a lower hardness value, but it cannot scratch minerals that are harder than itself, such as quartz or diamond.
Which mineral cannot scratch any mineral by itself?
Talc is the mineral that cannot scratch any mineral by itself. It has a Mohs hardness of 1, making it the softest mineral on the Mohs scale, which means it can be easily scratched by all other minerals.
Is it true or false mineral can scratch any mineral harder than itself?
false a mineral can not scratch any mineral harder than itself
Can a mineral scratch any mineral harder that itself?
No, it is just the opposite.
What mineral can scratch itself but no other mineral can scratch it?
A diamond is the only material that cannot be scratched by any other than itself.
Is the following question true or false a mineral can scratch any mineral harder than itself?
True. In general, a mineral can scratch any mineral that is softer than itself according to Mohs Scale of Mineral Hardness. This means that a mineral with a higher number on the scale can scratch a mineral with a lower number.
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.
Would a mineral of a hardness of 9 leave a streak Why or why not?
A mineral with a hardness of 9, such as corundum, would not leave a streak on a streak plate because it is harder than the plate itself, which typically has a hardness of about 6. A harder mineral cannot scratch a softer material, so it wouldn't produce a streak. Streak is determined by the powder left behind when a mineral is scraped against a harder surface, and since the mineral is too hard, it cannot do so.
How do you determine how soft a mineral is?
The hardness of a mineral is categorized on the Mohs hardness scale with talc as 1 and diamond as 10. A mineral can only be scratched bya mineral that is as hard or harder than the first mineral. So talc can scratch talc but nothing else. A diamond can scratch every other mienral including itself. Cordundum with a hardness of 9 can't scratch diamonds but can scratch a lot of other minderals.
If a mineral can scratch a penny what number is it on Mohs Scale?
Most of the time, no. But there are some minerals, such as kyanite, that have more than one hardness in an individual crystal. But this is an exception to the Mohs scale of mineral hardness, which is based on the premise that a mineral of a lower number cannot scratch a mineral of a higher (harder) number.
What minerals can gymsum scratch?
Gypsum, which has a Mohs hardness of 2, can scratch minerals that are softer than itself, such as talc (hardness 1) and calcite (hardness 3). Therefore, it can scratch talc but not calcite or any harder mineral. Other minerals that gypsum can scratch include some varieties of gypsum itself, like selenite.
Can talc scratch over minerals?
Talc is the softest mineral on the Mohs scale with a hardness of 1, so it can be easily scratched by harder minerals. Talc can scratch over minerals with a lower hardness value, but it cannot scratch minerals that are harder than itself, such as quartz or diamond.
Which mineral cannot scratch any mineral by itself?
Talc is the mineral that cannot scratch any mineral by itself. It has a Mohs hardness of 1, making it the softest mineral on the Mohs scale, which means it can be easily scratched by all other minerals.
What mineral can scratch all the minerals?
Diamonds are proven to scratch all minerals including itself.
