What is a mineral determined by using a fingernail penny or nail?
A mineral's hardness can be determined using a fingernail, penny, or nail by testing its ability to scratch or be scratched by these objects. The Mohs scale of hardness ranks minerals from 1 (talc) to 10 (diamond), with a fingernail typically rated at 2.5, a penny at about 3.5, and a nail around 5.5. By attempting to scratch the mineral with these items, you can estimate its hardness based on which objects can scratch it and which cannot.
How could you find out the relative hardness of three minerals if you had no tools and couldn't use your fingernail?
You could perform a scratch test by trying to scratch one mineral with another. Whichever mineral leaves a mark or scratch on the other is harder. By comparing the results of scratching each mineral with the others, you can determine their relative hardness.
What is the characteristic of a mineral that is revealed by testing what substances can scratch it and what the mineral can scratch?
it is hardness
When testing for hardness which is softest?
Talc (a common metamorphic mineral).
What is it called when you scratch a mineral across a plate to see its color?
It is called streak testing.
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.
A mineral that can by a steel file The property you are testing is the mineral's?
Hardness
What mineral property if you testing if you scratch a mineral on ceramic tile?
You're testing it's hardness.
What property are you testing when you drip dilute hydrochloric acid on a mineral sample?
You are testing the reaction of the mineral with an acid to determine its composition. Some minerals react with acid by fizzing or bubbling, which indicates the presence of carbonate minerals.
If you squeeze a few drops of acid onto a mineral sample and watch for bubbles what property are you testing?
By squeezing a few drops of acid onto a mineral sample and observing for bubbles, you are testing for the mineral's reactivity with acid, which indicates the presence of carbonate minerals, such as calcite or dolomite. The bubbling occurs due to the release of carbon dioxide gas when the acid reacts with the carbonate. This property is commonly used in mineral identification to determine if a sample contains carbonates.
Does the density of a mineral depend on the size of the mineral sample?
No, to tell how hard a mineral is you either have to test it or determine what mineral it is. Testing uses materials of known hardness such as a fingernail, or copper penny, or scratch plate, if the mineral is scratched by whatever you use to test it is softer. Hardness however is not based on size it will be the same for any sample of the same rock no matter what the size because its based on atomic arrangement and bond type.
How to determine the hardness of a mineral?
The hardness of a mineral can be determined by using the Mohs scale of hardness, which ranks minerals from 1 (softest) to 10 (hardest). This scale is based on the ability of one mineral to scratch another. By testing the mineral's resistance to scratching with common objects of known hardness, such as a fingernail (2.5), a copper penny (3.5), a steel nail (5.5), and a glass plate (5.5), you can determine its hardness level.
What is the most reliable physical property that can be used to identify a mineral?
The most reliable physical property to identify a mineral is its chemical composition. This is because each mineral has a unique combination of elements that make up its structure, which can be determined through chemical testing. Additionally, properties like hardness, cleavage, and specific gravity can also aid in identifying minerals.
