In an extraction procedure, it is advisable to: save all layers until the experiment is complete. throw away all layers as soon

as you have extracted them. put the aqueous layer down the drain. put the organic layer in the aqueous waste.

All the layers should be kept until the experiment is complete.

<h3>What is extraction?</h3>

In chemistry, solvent extraction is accomplished by adding a sample containing the substance to be separated into a system of two solvents, an aqueous layer and an organic layer.

It is important to note that all the layers should be kept until the experiment is complete. No layer ought to be discarded before the work is completed.

What is the orbital diagram for fluorine?
pogonyaev

Explanation:

The orbital for fluorine is 1s 2s 2p. All of the boxes should be filled COMPLETELY until you can't no more. How do you know if you can't anymore? By the <u>atomic number</u> of the element. The atomic number for fluorine is 9. So, you keep adding arrows starting from the first box all the way to the last until you have reached the atomic number, in this case, 9.

Consider a wildflower population with the following allele and genotype frequencies. Frequency of the CR allele: p = 0.6 Frequen
k0ka [10]

NO,  It Isn't

Ideally a population in Hardy Weinberg equilibrium should hold true to the following equation for genotypic frequencies of an allele;

P² + 2pq + q² = 1

Explanation:

We are provided with allelic frequencies hence we can derive the genotypic frequencies; (CR allele: p = 0.6 Frequency of the CW allele: q = 0.4)

P² = 0.6 ^2 = 0.36

2pq = 2 * 0.6 * 0.4 = 0.48

q² = 0.4 ^ 2 = 0.16

Lets find out if all add up to  as supposed to;

0.36 +  0.48 + 0.16 = 1

Converting to percentages is easy – just multiply by 100

  • 36 % CRCR
  • 48% CRCW
  • and 16 % CWCW

The population provided is not in equilibrium because their percentages vary widely to that the expected Hardy Weinberg's equilibrium percentages. This could be attributed to factors like;

  1. Migration
  2. Mutations,
  3. There is natural selection in progress in the population
  4. There is gene flow

What types of predictions can be made using the Periodic Table?
Andrej [43]
Periodic trends are specific patterns that are present in the periodic table that illustrate different aspects of a certain element, including its size and its electronic properties. Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. Periodic trends, arising from the arrangement of the periodic table, provide chemists with an invaluable tool to quickly predict an element's properties. These trends exist because of the similar atomic structure of the elements within their respective group families or periods, and because of the periodic nature of the elements.
