Every thing
What is meant by a characteristic property of a substance?
Since characteristic properties for a given substance never change, they can be used to identify unknown matter.
Why do you think scientists can use basic properties of matter to help identify an unknown substannce?
Why don't you read section 1-2 in you packet? Therefore the answer is in there
When examining the physical properties of an unknown substance characteristics is unsafe to observe?
This depends on the nature of this substance; precautions are necessary.
Kelly has a sample of an unknown substance. Which properties of the substance will be the same no matter how large or small her sample is?
All intrinsic properties will be the same regardless of sample size. Some examples would be density, color, temperature, chemical reactivity, etc.
Why Do You Think Scientists Can Use The Basic Properties Of Matter To Help Identify An Unknown Substance?
Because if a substance can't be known then it has to prove its mass and volume

If you had an unknown substance and were asked to identify it would you use the intensive or extensive properties of the substance?
Intensive properties are independent from the mass of an object: density, hardness, melting point.

Knowing the solubility of an unknown substance in water can help to identify what it is.?
Knowing the solubility of an unknown substance in water can help you calculate its molarity. It is however important to get its weight first.
Which properties can you use to identify an unknown mineral?
chemical analysis
Why are characteristic properties helpful in identifying an unknown substance?
melting point.
How do forensic scientists analyze unknown powders?
Forensic labs are often called in to identify unknown powders, liquids and pills that may be illicit drugs. There are basically two categories of forensic tests used to analyze drugs and other unknown substances: Presumptive tests (such as color tests) give only an indication of which type of substance is present -- but they can't specifically identify the substance. Confirmatory tests (such as gas chromatography/mass spectrometry) are more specific and can determine the precise identity of the substance.

How do you identify an organism with technology?
If an organism is very small, scientists use a microscope to try and identify it. In extreme cases, scientists can study the DNA of an unknown organism and compare it to a database to figure out what it is.
Mendeleevs periodic table was useful because it enabled scientists to predict properties of unknown?
elements
