If an unknown mineral has a hardness between 5 and 9 what could you do to the mineral to find out more about its hardness?
To determine the hardness of an unknown mineral with a hardness between 5 and 9, you can perform a scratch test using various reference minerals or materials with known hardness values from the Mohs scale. Start by testing the unknown mineral against a mineral with a hardness of 5, such as apatite, and gradually work your way up to harder minerals, like quartz (7) and topaz (8), until you observe whether the unknown mineral can scratch or be scratched by them. This will help you narrow down its hardness range more precisely. Additionally, using tools like a hardness kit with standardized materials can offer a more accurate assessment.
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.
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 an hypothesis for mineral identification?
A hypothesis for mineral identification could be that specific physical and chemical properties, such as hardness, color, luster, and crystal structure, can be used to accurately classify minerals into distinct categories. For example, "If a mineral exhibits a Mohs hardness of 7, a vitreous luster, and a cubic crystal habit, then it is likely to be identified as quartz." This hypothesis can be tested by examining various minerals and comparing their properties to known standards.
How do you treat hardness in groundwater?
Hardness in groundwater could simply be treated by Heating the water to a considerable temperature. Chlorination and Distillation could also be applied to groundwater hardness treatment.
How could you determine the hardness rating for a mineral not listed on the scale?
Moh's Scale of Hardness # Talk # Gypsum # Calcite # Fluorite # Apatite # Orthocalse Feldspar # Quartz # Topaz # Corundum # Diamond Has only 10 minerals in it. There are literally 100s if minerals to be found in the rocks that are not used in the scale but that can have their hardness related to the scale. e.g. graphite, galena, beryl, zircon etc.
What property might you test by rubbing one mineral directly against another mineral?
You could test for the property of hardness by seeing which mineral scratches the other. The mineral that scratches the other is the harder one.
Is unknown opaque a non-metallic mineral?
You do not provide enough information for us to answer this question.
What can scratch peridot?
A peridot could scratch any mineral with a Mohs hardness of 6.5 or less. Click on the link below for information on the Mohs hardness scale.
What mineral you can scratch with your fingernail?
The most commonly known mineral that can be scratched with a fingernail is talc.
Suppose you have two mineral samples with the same hardness What other mineral properties could you use to decide whether the two samples are the same mineral?
You could use properties such as cleavage, streak color, color, density, luster, and crystal habit to differentiate between the two samples. These properties can help determine if the samples are the same mineral or different minerals, even if they have the same hardness.
What are ways to test a mineral?
You could test for hardness, streak, cleavage, fluorescence, reaction to acid, radioactivity, flame test, etc.
Could corundum scratch topaz?
Yes. Corundum will scratch topaz and every other mineral with a hardness of 9 or lower on the Mohs hardness scale.
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.
A student broke a mineral sample with a type of a hammer on a sharp chisel what property is he investigating?
He is either investigating if it is facture or cleavage. Or he could be trying to test it's hardness. He is either investigating if it is facture or cleavage. Or he could be trying to test it's hardness.
Why is the hardness of a rock sometimes referred to as a scratchability?
Sometimes the concept of hardness is confused with whether or not a mineral will break. It is important to understand that even though a diamond is extremely hard, it can shatter if given a hard enough blow in the right direction along the crystal. Hope this helps!
Mineral X is scratched by a diamond. Mineral X .?
Mineral X could be anything. Diamond is the hardest mineral (10 on Mohs' scale) and can scratch all other minerals including another diamond.
