Choose a depiction of a gas sample containing equal molar amounts of xenon and argon as described by kinetic molecular theory. R

ed dots are used to represent xenon atoms and blue dots to represent argon atoms. Each atom is drawn with a "tail" that represents its velocity relative to the others in the mixture.

Answer:

On the attached picture.

Explanation:

Hello,

At first, it is important to remember that kinetic molecular theory help us understand how the molecules of a gas behave in terms of motion. In such a way, the relative velocity of a gas molecule has the following relationship with the gas' molar mass:

V∝\frac{1}{\sqrt{M} }

That is, an inversely proportional relationship which allows us to infer that the bigger the molecule the slower it. In this manner, as argon is smaller than xenon, it will move faster.

Now, as the gases are in equal molar amounts and considering that argon moves faster, on the attached picture you will find the suitable depiction of the gas sample, since red dots (argon) have a larger tail than the blue dots (xenon).

Best regards.

Answer:

<u>Kinetic Molecular theory(KMT):</u>Each molecules or atom of any gas is in a constant motion, and will have an elastic form of collision with other atoms present along with it inside any enclosed area or container.

And, the total kinetic energy of the molecules will be equal to the total or absolute temperature possessed by the number of atoms which are in motion inside the enclosed container.

Explanation:

<u>Xenon and Argon's molecules inside a container:</u>

When we study the properties of argon,Ar and xenon,Xe the denser molecule is the later one.As, the density of xenon,Xe is around 5.761 kg/m³, while the argon's density is about 1.7838 kg/m³. So, obviously the moment of argon's molecules will be more then that of xenon's. And the "tail" drawn with the molecules will be highlighted with high value of velocity inside the diagram.

calculate the atomic number of an element whose neutral atom has four electrons in its valence shell and its valence shell is th
insens350 [35]

Answer:

The atomic number of the atom is 14.

Explanation:

The following data were obtained from the question:

Valence electrons = 4

Atomic number =.?

From the question given, we were told that the valence electron is in the m shell. Thus, we can say:

M shell = 4 electrons

The number of shells of the atom can be written in the order K, L, M with M as the last shell because we were told that the valence electrons i.e electrons in the outer shell is located at the M shell.

From a detailed knowledge of atom,

K shell = 1st shell

L shell = 2nd shell

M shell = 3rd shell

The first shell, K of an atom can only accommodate 2 electrons while others can accommodate a maximum of 8 electrons.

Note: we can only put electrons in another shell if a shell is already having 8 electrons. This rule only applies to the 2nd shell and above.

Thus, the atom in question has the following electrons:

K shell = 1st shell = 2 electrons

L shell = 2nd shell = 8 electrons

M shell = 3rd shell = 4 electrons

To get the atomic number of the atoms, we simply add all the electrons together.

This is illustrated below:

Atomic number = 2 + 8 + 4

Atomic number = 14

Therefore, the atomic number of the atom is 14.

We say that salts will dissociate but acids will react with water. We say that acids will
Paha777 [63]

Answer:

ionize

Explanation:

Acids are chemical substances that lose/donate their hydrogen ion (H+) when they react with water. This property of acids is termed IONIZATION. In a chemical reaction involving acids and bases, acids release their proton or hydrogen ion (H+) in the presence of water solutions to form a conjugate base, which is usually an anion.

For example, in the chemical reaction;

HX + H20 -------> X- + H30+

HX is the acid because it loses its electron to water and forms the anion, X-, which is the conjugate base. Hence, it can be said that acid HX ionizes in water.

A sample of gas has a volume of 3.75 L at a temperature of 25°C and a pressure of 1.15 atm. What will the volume be at a tempera
omeli [17]

Answer: V = 5.1 L

Explanation: To find the new volume, we will use the formula of Combined Gas Law and derive V2. We also need to convert first the temperature in Kelvin and convert torr to atm ( 1 atm = 760 torrs ).
