Which mineral can be scratched by glass but not a penny?
The mineral that can be scratched by glass but not a penny is calcite. Calcite has a hardness of 3 on the Mohs scale, which is lower than the hardness of glass (5.5) but higher than that of a penny (2.5).
What mineral can be scratched by a penny but not a fingernail?
Copper sulfide minerals, such as chalcocite and bornite, can be scratched by a penny but not a fingernail. This is due to the Mohs hardness scale, where these minerals have a hardness greater than a penny (3.5) but less than a fingernail (2.5).
What mineral can only be scratched by one mineral?
Diamond is the hardest mineral and can only be scratched by another diamond.
What property are you testing if you scratch a mineral with a penny a nail and your fingernail?
When you scratch a mineral with a penny, nail, and your fingernail, you are testing the mineral's hardness. The ability to scratch or be scratched by certain materials helps determine the mineral's hardness on the Mohs scale of mineral hardness.
Which mineral would a penny scratch?
A penny would scratch minerals with a lower hardness rating such as calcite, gypsum, or talc. Minerals like quartz or topaz would not be scratched by a penny because they are harder than the metal in a penny.
Which mineral can be scratched by glass but not a penny?

A mineral determined by using fingernailpenny or nail?
A mineral can be tested for hardness using a fingernail, penny, or nail, which are common items that serve as reference points on the Mohs scale of mineral hardness. For instance, a fingernail has a hardness of about 2.5, while a copper penny is around 3.5. If a mineral can be scratched by a fingernail, it is softer than 2.5; if it can be scratched by a penny but not a fingernail, it falls between 2.5 and 3.5. This simple test helps in identifying the mineral's hardness and assists in classification.
Which would be the hardness of a mineral that can be scratched by a penny but not a fingernail?
A mineral that can be scratched by a penny (which has a hardness of about 3.5 on the Mohs scale) but not by a fingernail (which has a hardness of about 2.5 to 3) would have a hardness between 3 and 3.5. This means the mineral's hardness is likely around 3.2 to 3.4, indicating it is softer than the penny but harder than a fingernail. Examples of minerals that fit this description could include calcite or gypsum, depending on their specific characteristics.
What mineral is nonmetallic and black and can be scratched by a penny?
The mineral you are describing is likely talc. Talc is a nonmetallic mineral that is typically black in some varieties and has a very low hardness of 1 on the Mohs scale, allowing it to be easily scratched by a penny, which has a hardness of about 3. Its softness and slippery feel are characteristic of talc, making it commonly used in products like talcum powder.
What mineral can only be scratched by one mineral?
Diamond is the hardest mineral and can only be scratched by another diamond.
What mineral cannot be scratched by another mineral?
A diamond. Actually, a diamond can be scratched my other minerals.

What mineral that you can't scratch with your fingernail but a copper penny will?
The mineral that you can't scratch with your fingernail but can be scratched by a copper penny is calcite. Calcite has a hardness of about 3 on the Mohs scale, while fingernails have a hardness of around 2.5. A copper penny, which has a hardness of approximately 3.5, can easily scratch calcite.
Can granite be scratched by a penny?
