If a person had not drunk any water for 8 hours before collecting a sample, would you expect his/her urine to have a high or low
Mrrafil [7]

Answer:

The person’s urine will have a high specific gravity

Explanation:

A high specific gravity is characterized by an increased concentration of solutes in the urine of am individual. A low specific gravity is characterized by a low or decreased concentration of the solutes.This is usually due to dehydration as a result of environmental conditions or tedious physical activities.

This explains why a person who had not drank any water for 8 hours and is dehydrated before collecting a sample is thought to have a urine with a high specific gravity

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.
