How can you identify a unknown compound using uv spectroscopy?
Each compound has a specific absorption spectra.
An unknown sample with a molecular mass of 180.0g is analyzed to yield 40 percent C 6.7 percent H and 53.3 percent O What is the empirical formula and the molecular formula of this compound?
ch2o and c6h12o6
What is nitrogen rule?
If a compound contains an even number of nitrogen atoms (or no nitrogen atoms), its molecular ion will appear at an even mass number. If, however, a compound contains an odd number of nitrogen atoms, then its molecular ion will appear at an odd mass value. This rule is very useful for determining the nitrogen content of an unknown compound.
Students want to identify a rock in a nearby field. Which of the following properties would be most useful in identifying the unknown rock?
Mineral content
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.
Which properties can you use to identify an unknown mineral?
chemical analysis

Name several properties of matter that help you identify an unknown substance?
Every thing
Why wouldn't a scientist use sour taste to identify a compound as a acidic?
Obvious safety issues in tasting unknown chemicals

ch2o and c6h12o6
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.
What are properties could be used to identify an unknown material?
smell, permeablity, gas liquid solid plasma??, size, shape, taste

How can a mixed melting point confirm the identity of an unknown compound?
The melting point is not enough to definitely identify the compound because different compounds may have a similar melting point range. It all depends on the compounds. If you have a compound of acetanilide and flourene, the results will lead to similar melting points of 115 degrees Celsius and 116 degrees of Celsius. The ranges will be similar so it would be hard to definitely identify the compound.
Why do you think scientists can use basic properties of matter to help identify an unknown substannce?
