Question
Chapter 29, Problem 29.8QAP
Interpretation Introduction
(a)
Interpretation:
The on-line and off-line process for SFE has to be differentiated.
Concept introduction:
When the source is directly available for data extraction process, it is called as on-line extraction method or process.
In off-line process, the data is utilized from other source that contains the copy of data and data extraction is done.
Interpretation Introduction
(b)
Interpretation:
Thestatic and dynamic extraction should be differentiated for SFE.
Concept introduction:
When the fixed amount of supercritical fluid is interacting with the matrix or analytes, it is called as static extraction method and it conserves the fluid.
In dynamic extraction method, there is always a new supercritical fluid that is used for interaction with matrix or analytes.

Students have asked these similar questions
For each reaction below, decide if the first stable organic product that forms in solution will create a new CC bond, and check
the appropriate box.
Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below.
Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions
- just focus on the first stable product you expect to form in solution.

As the lead product manager at OrganometALEKS Industries, you are trying to decide if the following reaction will make a molecule
with a new C - C bond as its major product:
H₂N
O
H
1.
?
2. H3O+
If this reaction will work, draw the major organic product or products you would expect in the drawing area below. If there's more
than one major product, you can draw them in any arrangement you like. Be sure you use wedge and dash bonds if necessary, for
example to distinguish between major products with different stereochemistry.
0
If the major products of this reaction won't have a new CC bond, just check the box under the drawing area and leave it blank.
