Answer:
The first energy level is closest to the nucleus. The second energy level is a little farther away than the first. ... The electrons in the energy level farthest from the nucleus are called valence electrons. Atoms in the same column (group) in the periodic table have the same number of valence electrons.

Explanation:
Chromatography is a technique for the separation of a mixture by passing it in solution or suspension through a medium in which the components move at different rates.Chromatography is also used to help catch criminals.Spoilage detection. Chromatography can be used in flavor studies and to detect spoilage in foods. Used in additive detection and used in determining nutritional quality.
It is not practical to use in scientific experimentation to test the effect of an octave on the quality of a song. There are so many scientific experimentations to test the effect that can be count practical like the color on brain waves and function, adrenaline on the response time of carnivores, nutrients on the gender of offspring and much more. Scientific Experimentation has an organized process and detailed series of steps to reject or validate a hypothesis. It is also a third step in scientific method. Researcher use experimentation to test a new hypothesis or theories to approve or support and disapprove them.
The correct answer for this question is this one:
<span>2. acidic, because the anion hydrolyzes to a greater extent than the cation.
3. basic, because the cation hydrolyzes to a greater extent than the anion.
5. neutral, because the cation hydrolyzes to a greater extent than the anion.
7. neutral, because NH4OCN is a weak base/weak acid salt. 8. basic, because the cation and the anion hydrolyze to the same extent.
10. neutral, because the cation and the anion hydrolyze to the same extent.</span>
Hope this helps answer your question and have a nice day ahead.
