What else can I help you with?
Which mineral has the same hardness as a fingernail?
Gypsum has a hardness of 2 on the Mohs scale, which is similar to the hardness of a fingernail.
Can halite be scratched by a fingernail?
Marginally. Halite has a hardness of 2 to 2.5, about the same as a fingernail.
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.
What mineral you can scratch with your fingernail?
The most commonly known mineral that can be scratched with a fingernail is talc.
Can talc be scratched by a fingernail?
Talc i assigned a hardness of 1 according to the Mohs scale of hardness. This implies that talc has the least hardness and therefore is soft and can be scratched by a fingernail.
Which mineral has the same hardness of a fingernail?
The mineral that has a similar hardness to a fingernail is gypsum. Gypsum has a Mohs hardness of 2, which makes it soft enough to be scratched by a fingernail.

Marginally. Halite has a hardness of 2 to 2.5, about the same as a fingernail.
What mineral property are you testing if a fingernail scratches a mineral?
If a fingernail can scratch a mineral, you are testing the mineral's hardness. Hardness is a measure of a mineral's resistance to being scratched by other materials. Minerals are ranked on the Mohs scale of hardness from 1 (softest) to 10 (hardest).
What is used to test the hardness of a a mineral?
The Moh's scale is used to test the hardness of a mineral. It will be tested by a fingernail scratching it.
What is the fingernail test?
The fingernail test is for minerals and if a mineral is soft then you stick your fingernail in the mineral and if it is below 10 on the moh's hardness scale then it can put a dent into the mineral hope that helps!!
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.
Which mineral can be scratched by a fingernail?
The most commonly known mineral that can be scratched by a fingernail is talc.
