Which properties can you use to identify an unknown mineral?
its weight
What are seven physical properties used to identify unkown materials?
To identify a property, the first step you have to do is to decide which property you want to experiment with. Then, you test on a sample which is unknown. Finally, you compare and contrast the data with the known properties. :)Peace. :)
What physical properties other than specific heat could you use to help you identify unknown samples of metals?

Unknown compounds can usually be identified based solely on their physical properties?
is it ture or falae that unknown compounds can ususally be identified based soley on their physical properties/
Why is it important to identify unknown minerals?
you can sell minerals but you can also use them for useful thing like surgery and tools
What physical properties are used to caculate the density of an object?
Mass and Volume are physical properties that can bed measured. By themselves, neither can bed used to identify unknown objects or substances. However, if you have measured the mass and the volume of an object, you can calculate its density.
What are the properties used to identify an unknown substance intensive or extensive?
Intensive property
How can an unknown mineral be identified?
The mineral's physical properties can be tested.
How can you identify unknown minerals?
you need to determine; hardness, color, transparency, and how they break. Those 4 combined will identify most minerals. There are other tests, but they get more complicated.
How can physical properties of matter can help identify unknown substances?
You often use the properties of a substance to identify it. For example, when you reach into your pocket, you can tell the difference between a ticket stub and a folded piece of tissue because one is stiff and smooth and the other is soft.
Name several properties of matter that help you identify an unknown substance?
Every thing
If you had an unknown substance and were asked to identify it would you use the intensive or extensive properties of the substance?
Intensive
What are 3 quantitative physical properties that could be used to help identify an unknown metal?
how much something weighs (density) a quantitative observation is also a measurement consist of a number and a unit
Is it true that Unknown compounds can usually be identified based solely on their physical properties?
it is not true that some compounds can usually be indetified based solely on their physical properties.
What type of properties are used to identify unknown substances?
Texture = feels, Flexibility = bend, Color = Looks...
What are the 5 main properties used to determine unknown minerals?
Minerals may be identified by their color, streak color, hardness, luster, and cleavage/fracture.
How can matter be identified by its physical and chemical properties?
This is not just a college course, but a study lasting more than a lifetime if you're wanting a complete listing. So I'll just note that in general, you can identify a compound by comparing the physical and chemical properties of your unknown sample to those of known materials and leave it at that.
How can you identify an unknown mineral sample?

What is meant by a property of a substance?
Since characteristic properties for a given substance never change, they can be used to identify unknown matter.
What are the different characteristics that can be used to identify an unknown mineral?
You can test its hardness on other minerals to find it hardness. It can help classify it better.
What is a way in which chemical properties are used?
Chemical properties can be used for building chemical classifications. They can also be useful to identify an unknown substance or to separate or purify it from other substances.
