Why would you never use the sour taste property to identify an unknown acid?
Because it might dissolve your tongue or poison you!
Why might it be helpful to know the specific gravity of a mineral?
If we know the physical or chemical properties of substances (including minerals) we can identify these minerals easier.
What is the one or two letter character used to identify an element?
The character(s) used to identify an element depends on the element. For example, one character elements can be S (sulfur), O (oxygen), N (Nitrogen) etc. Some example of two letter elements might be sodium (Na), silver (Ag), gold (Au), magnesium (Mg), and others.
Why do scientist would want to know the colors of metals when burning?
One good reason is to identify an unknown compound or element. The flame colour also might give an indication of the chemical makeup of a compound, i.e. what types of bonds it has. As each bond will give out a different amount of energy when broken, giving different colours. So, the simple answer is to find out what something is.
How you might use Rf values to identify an unknown substance?
Although Rf values technically remain constant if the following are held constant: * solvent system * adsorbent * thickness of the adsorbent * amount of material spotted * temperature They are generally not used to identify an unknown substance specifically, since these factors are sometimes difficult to control. Most generally, during a chromatography experiment an unknown sample can be compared directly to a known sample simultaneously, i.e. they will have similar Rf values.
What relationship between the known and unknown do you need to solve the problem?
As part of planning, you might draw a diagram that helps you visualize a relationship between the known and the unknown. You might need to use a table or graph to identify data or to identify a relationship between a known quantity and the unknown. Hope that helps (:
How can you identify an unknown animal fur?
TO be totally sure, it could be DNA tested. Otherwise, a taxidermist might have a good guess.

What difficulties might you encounter if you tried to identify an unknown substance using its boiling point?
You might make it explode or make some deadly gas. Research what you're doing before you perform an experiment.
