Answer to Question #217715 in General Chemistry for Green

Question

1.     Distinguish between the following:

a.     Compatible and incompatible elements

b.     Extensive and intensive variables

                                                                                                                                       

Answer 1

Incompatible elements are too large or too highly charged to fit easily into rock-forming minerals that crystallize from melts. They become concentrated in melts. 

Compatible elements are elements that fit easily into rock-forming minerals, and may in fact be preferred. 

Extensive and intensive variables are the two types of physical properties of matter.

Intensive variables do not depend on the amount of matter in a substance. Examples include state of matter, temperature, and density.

Extensive variables depend on the amount of matter in a sample. Examples include mass, length, and volume.
