What are four characteristics of mineral which can be used to identify it?
Color, streak color, hardness, cleavage, and chemical.
Which mineral properties are most useful for identification?
Hardness and streak color are very important. The color of the mineral helps some, as well.
What is the eight ways to identify a mineral?
By the mineral color, streak color, luster, hardness, the property of the mineral, if it's fracture or cleavage and it's specific gravity. Those are just basic, so there's many other ways to ID a mineral.
Can you identify a mineral by its physical properties?
Color, reflectivity, purity. Just to name a few.
What is the Color of a mineral when crushed to a powder?
Different minerals have different colors, actually.
Would the hardness of a mineral affects its performance in the streak test why or why not?
No. Streak color is distinct of mineral hardness. They are separate properties.
Would the hardness of a mineral affect its performance in the streak test Why or why not?
No. Streak color is distinct of mineral hardness. They are separate properties.
What is the difference between streak and hardness?
A minerals hardness is its relative ability to scratch or be scratched by other minerals. Diamond, for instance, can scratch all other minerals because of its hardness. Streak is the color of the mineral when powdered. This is usually accomplished by the streak test (swiping the mineral across an unglazed porcelain surface) which reveals a mineral's streak color, which may differ from the color of the specimen being tested.
What are the the tests scientists use to identify minerals?
Hardness test based on the Mohs Scale of relative mineral hardness, specific gravity, streak test for mineral color, classification of mineral crystal system, chemical analysis.
What properties does a mineral?
color, luster, fracture/cleavage, streak, hardness, density

Color, streak color, hardness, cleavage, and chemical.
What is difference between hardness and streak?
Streak is the color it makes when two minerals scratch against each other. Hardness is just how hard the mineral is

What is Cobalts mineral streak color?
Yes. Its Mohs hardness is in the range of 5, and minerals (or metals, as is the case here) will streak up to a hardness of about 7. For a quick review of what streak is and how it originated, use the link to the Wikipedia article.
What is more reliable than color as an indicator of a mineral's identity?
Streak, hardness, and crystalline structure.
What is the difference between a scratch test and a streak test?
a streak test is a test wheree you rub a mineral across a streak plate to see the color of its streak, which is a better indentifying factor of the mineral than the external color. A scratch test is when you scratch a mineral to find out its hardness on the Mohs Scale of Hardness. This is also another useful identifying factor
