explain the concept of kenetic molecular theory

Answers

Answer 1
Not sure if you meant kinetic.. The theory states that gas particles are in constant motion and exhibit perfectly elastic collisions. The theory is based on the idea that matter is composed of tiny particles that are always in motion.

Answer:

I believe A is the correct answer.

Explanation:

I note that another response includes C. as another correct answer.  It is possible, but it depends on what is meant by "fixed shape."  I interpret "fixed shape" as the collection of the gases forming a fixed shape on their own.  Gases fill the container they are in (be it a flask, room, or a planet, so they have a fixed shape by that definition.  But a primary definition of gases is that that take on the shape of their container, not a shape of their own.

A. is correct because perfect gases have no interactions (AKA the Ideal Gas Laws).  They may have interactions, and often do, but they are weak.  That's why the ideal gas laws are a good first approximation to how gases change volume based on temperature and pressure.

The reaction below is at dynamic equilibrium. Upper N subscript 2 (g) plus 3 upper H subscript 2 (g) double-headed arrow 2 upper N upper H subscript 3 (g). Which statement is true for the equilibrium system? The concentration of NH3 is greater than the concentration of N2. The concentration of NH3 equals the concentration of N2. The rate of the forward reaction equals the rate of the reverse reaction. The rate of the forward reaction is greater than the rate of the reverse reaction.

Answers

For the reaction below at dynamic equilibrium, it is true that the rate of the forward reaction equals the rate of the reverse reaction.

Let's consider the following reaction at equilibrium.

N₂(g) + 3 H₂(g) = 2 NH₃(g)

What is the chemical equilibrium?

Is a state in which the concentrations of reactants and products are constant and the forward reaction rate and constant reaction rate are equal.

What is the equilibrium constant?

The equilibrium constant (K) is the ratio of the concentrations of the products to the concentrations of the reactants, all raised to their stoichiometric coefficients.

Let's consider which statement is true for the equilibrium system.

The concentration of NH₃ is greater than the concentration of N₂. FALSE. There is not enough information to confirm this, we would need to know the value of K.The concentration of NH₃ equals the concentration of N₂. FALSE. There is not enough information to confirm this, we would need to know the value of K.The rate of the forward reaction equals the rate of the reverse reaction. TRUE. This is always true for a reaction at equilibrium.The rate of the forward reaction is greater than the rate of the reverse reaction. FALSE. At equilibrium, both rates are equal.

For the reaction below at dynamic equilibrium, it is true that the rate of the forward reaction equals the rate of the reverse reaction.

The two ways the cathode ray tube experiment changed scientists'

understanding of the atom was it showing that atoms can be divided into

smaller parts and all atoms contain electrons.

J.J Thompson was the scientist which performed the cathode ray tube

experiment and was able to ascertain it was negatively charged as a result

of it being deflected to the positive electrode.

His observation showed that the atoms contain sub-atomic particles called

electrons which are negatively charged.

An atom's electron configuration ends with 3p4. If another atom has seven more electrons, what would be the continuation of the electron configuration?

Answers

The continuation of the electron configuration would be [tex]3p^6, 4S^2, 3d^3[/tex].

The initial p orbital is partially filled. Hence, it has to be completely filled first in order to obey the orbital filling rule. Lower energy orbitals are first filled before higher energy orbitals.

After filling the p orbital with 2 electrons from the remaining 7 electrons, higher energy orbital 4s and 3d can then be filled.

As the day went on I started to get pretty warm and I starting to evaporate and fly into the sky! It was really weird to see the world from up high. I stayed up there bouncing between clouds with Bob for a few hours, until the wind started to pick up and it got colder. I then started to shiver and began condensing with the other water molecules (and Bob). As it got colder we began to plummet to the earth really fast in the precipitate form of a water droplet. We hit the ground with a big ker-plop! I looked around me and we weren't the only ones. A bunch of other droplets had started to collect and form a puddle.

Explanation:

When [tex]^1^8F[/tex] undergoes positron emission, the product nucleus is, [tex]^1^8O[/tex].

What is a positron emission?

In positron emission, also called positive beta decay (β+ decay), a proton in the parent nucleus decays into a neutron that remains in the daughter nucleus, and the nucleus emits a neutrino and a positron, which is a positive particle like an ordinary electron in mass but of opposite charge.

When a proton is converted into a neutron then the positron emission takes place as follows.

[tex]^1_1p\;\rightarrow\;^1_0n\;+\;^0_+1e[/tex]

A positron is represented by the symbol. Therefore, when a positron emission occurs then the resultant nuclei atomic number decreases by a unit mass.

The general equation representing positron emission is as follows.

[tex]^M_ZA\;\rightarrow\;^M_Z_-_1 B\;+\;^0_+1e[/tex]

Hence, fluorine-18 decays by positron emission as follows.

[tex]^1^8_9F\;\rightarrow\;^1^8_8n\;+\;^0_+1e[/tex]

Therefore, when [tex]^1^8F[/tex] undergoes positron emission, the product nucleus is, [tex]^1^8O[/tex].
