frutty [35]

Answer:

Hello your question is poorly written, the options and the question is all mixed up but i was able to pick out the correct answer.

answer <em>: A thin liquid layer that is chemically bonded to the interior of a capillary column that comes in contact with an inert carrier gas or mobile phase</em>

Explanation:

The stationary phase in gas Chromatography is best described as ( from the options listed in your question ) :

<em>A thin liquid layer that is chemically bonded to the interior of a capillary column that comes in contact with an inert carrier gas or mobile phase</em>

Gas chromatography is an analytical process  used to separate the chemical components ( usually gases )  found in a mixture sample

In dna replication, each individual parent strand acts as a _____ strand for the synthesis of a _____ strand.
irina [24]
The answer is template strand; daughter strand.

<span>In DNA replication, each individual parent strand acts as a <u>template</u> strand for the synthesis of a <u>daughter</u> strand. DNA replication is a process of producing of two identical copies of DNA from the original DNA. DNA molecule consists of two strands and each strand serves as a template strand for the synthesis of a daughter cell. DNA polymerase binds to the origins of replication and synthesises daughter strands by adding complementary nucleotides.</span>

Rank the following elements by increasing atomic radius carbon aluminum oxygen potassium
Vlada [557]

Answer:

The elements in increasing order of atomic radius: oxygen, carbon, aluminum, potassium

Explanation:

The distance from the center of the nucleus to the outermost shell of the electron is known as the atomic radius of an element. The atomic radius decreases rightward along each period (row) of the table due to the increase in effective nuclear charge (the charge of the nucleus equal to the number of protons). Across a period, electrons are added to the same energy level and the increasing number of protons causes the nucleus to exert more pull on these electrons, which makes the atomic radius smaller.  Atomic radius increases down each group (column) of the periodic table because of the addition of electrons to higher energy levels, which are further away from the nucleus and the pull of nucleus weakens. Another reason for the increase in atomic radius is the electron shielding effect, which is the reduction of the attractive force between a nucleus and its outer electrons due to the blocking effect of inner electrons

While moving from left to right in the second period, c arbon comes before  oxygen  and so oxygen will have a smaller atomic radius than  carbon. While moving down the periodic table, al uminum comes before  potassium even if they are not in the same period. So aluminum 's atomic radius will be smaller than that of  potassium  but bigger than that of  carbon  and  oxygen.
