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.
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 the difference between a minerals hardness and streak?
A minerals hardness is the ability to scratch or be scratched by other minerals and streak is the colored powder of a mineral that comes off when being scratched.
What is the most reliable clue in identifying a mineral?
hardness, luster, cleavage and fracture, color (not quite useful) and streak
What is the streak luster hardness and crystal system of petroleum?
Petroleum is not a mineral and does not possess these characteristics.

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.
If a mineral doesn't make a streak is it not a mineral?
Minerals with a hardness greater than around 7 on the Mohs hardness scale will not leave a streak on a standard unglazed porcelain streak plate. They will instead scratch and powder the streak plate.
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.
How do you test a mineral for hardness?
Well. You can do many things like use the Mohs Hardness Scale or determine the hardness by the streak.
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 test do geologists use to determine the hardness of a mineral?
the streak test
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.
If a mineral has no streak is it metallic?
When identifying minerals, having no streak is a property of hardness. A streak plate has a hardness of ~7(Moh's Scale). Thus any mineral having a hardness greater than 7 will have no streak.Metallic is the description of luster. Or the general appearance of a mineral surface in reflected light.If you were refering to the mineral having metal elements in it, streak is actually very useful for identifying them. Many minerals that are composed of non-metals have a white streak which can appear to be no streak, however there are also many minerals with no streak which are composed of non-metallic minerals (Diamond).
Why can't a streak test be done on a mineral whose hardness is greater than 7?
Because the mineral is harder than the ceramic streak plate.
What is it called when you perform a scratch test on a mineral?
It is called a streak and its purpose is to find the hardness of the mineral.
