What is the hardness of hematite?
Hematite is a 6.5 on the Mohs scale of mineral hardness.
What are 7 ways to determine the identity of a mineral?
Color: Observe the color of the mineral. Hardness: Use the Mohs scale to determine the mineral's hardness. Cleavage and fracture: Check how the mineral breaks. Luster: Determine if the mineral is metallic or non-metallic. Streak: Identify the color of the mineral's powdered form. Specific gravity: Measure the density of the mineral. Acid reaction: Test if the mineral reacts with acid.
What is the definition for the hardness of a mineral?
Hardness - measure of how easily a mineral is scratched.
What properties of minerals is expressed in numbers?
Some properties of minerals that can be expressed in numbers include hardness (using the Mohs scale), specific gravity (a ratio of the mineral's weight to the weight of an equal volume of water), and refractive index (a measure of how light bends as it passes through the mineral).
What scale compares resistance of the surfaces of minerals to scratching?
The scale that compares the resistance of the surfaces of minerals to scratching is called the Mohs scale of mineral hardness. It ranks minerals on a scale from 1 (softest) to 10 (hardest) based on their ability to scratch or be scratched by other minerals.
What compares weight of mineral with weight of an equal volume of water?
Specific gravity
What compares the weight of a mineral with the weight of an equal amount of water?
Specific gravity compares the weight of a mineral with the weight of an equal amount of water! :D
What is the hardness of hematite?
Hematite is a 6.5 on the Mohs scale of mineral hardness.
What mineral has a hardness of 7 is red no streak color and a specific gravity of 2.65?
It is definitely a form of the mineral quartz, maybe jasper or carnelian.
If a mineral is 10 times heavier than water what is its specific gravity?
The specific gravity of a mineral that is 10 times heavier than water would be 10. Specific gravity is a unitless measure that compares the density of a mineral to the density of water, which is 1 g/cm3.
What compare the weight of a mineral with the weight of an equal amount of water?
Specific gravity compares the weight of a mineral with the weight of an equal amount of water! :D
What does the term property of a mineral mean?
Property would refer to any identifier of the mineral, such as chemistry, hardness, luster, specific gravity, streak, melting point, etc..
What is the harness of a mineral if it scratches a penny but will not scratch glass?
Google "Mohs hardness scale". This is a relative hardness scale which compares one mineral's hardness to another. (It is between 3.5 and 5.5 on the Mohs hardness scale)
What 2 properties of minerals can be expressed in numbers?
Two properties of minerals that can be expressed in numbers are hardness and specific gravity. Hardness is usually determined using the Mohs scale and is expressed as a number between 1 (softest) and 10 (hardest). Specific gravity is the ratio of a mineral's density compared to the density of water and is expressed as a number.
What are 7 ways to determine the identity of a mineral?
Color: Observe the color of the mineral. Hardness: Use the Mohs scale to determine the mineral's hardness. Cleavage and fracture: Check how the mineral breaks. Luster: Determine if the mineral is metallic or non-metallic. Streak: Identify the color of the mineral's powdered form. Specific gravity: Measure the density of the mineral. Acid reaction: Test if the mineral reacts with acid.
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 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.
