Answer:
Phosphorous has the smallest atomic size.
Explanation:
As we know these elements belong to same period means there valence shell is the same. So moving from left to right along the period the shell number remains constant but the number of protons and electrons increases. So, due to increase in number of protons the nuclear charge increases hence attracts the valence electrons more effectively resulting in the decrease of atomic size.
Elements and their atomic radius are as follow,

Non-volatile mixtures can be separated using a process called thin layer chromatography (TLC). Since acetaminophen has a hydroxyl group, it is more polar than phenacetin.
<h3>Does acetaminophen or phenacetin have a lower Rf value?</h3>
Since acetaminophen has a hydroxyl group, it is more polar than phenacetin. Phenacetin will be more soluble and migrate to the top than the polar component because we are employing a non-polar solvent.
Non-volatile mixtures can be separated using a process called thin layer chromatography. The experiment is carried out on a piece of glass, plastic, or aluminum foil that has been lightly covered with an adsorbent substance. Typically, silica gel, cellulose, or aluminum oxide are utilized as the substance.
Because acetaminophen is more polar than phenacetin and nonpolar molecules pass through silica gel more quickly than polar ones do, acetaminophen would have a lower Rf value.

Answer:
60.0mL of the diluted solution are needed
6.00mL of the 1.00M NaOH stock solution is the minimum volume needed to prepare the diluted solution.
Explanation:
As in each titration we need to use 20.0mL of the diluted 0.100M solution. As there are 3 titration, the volume must be:
3 * 20.0mL = 60.0mL of the diluted solution are needed
Now, to prepare a 0.100M NaOH solution from a 1.00M NaOH stock solution the dilution must be of:
1.00M / 0.100M = 10 times must be diluted the solution.
As we need at least 60.0mL, the minimum volume of the stock solution must be:
60.0mL / 10 times =
<h3>6.00mL of the 1.00M NaOH stock solution is the minimum volume needed to prepare the diluted solution.</h3>
