A chemical reaction is at equilibrium. Compared to the rate of the forward reaction, the rate of the reverse reaction is(1) faster and more reactant is produced
(2) faster and more product is produced
(3) the same and the reaction has stopped
(4) the same and the reaction continues in both directions

Answers

Answer 1
Answer:

A chemical reaction is at equilibrium. Compared to the rate of the forward reaction, the rate of the reverse reaction is  the same and the reaction continues in both directions and the correct option is option 4.

What is Chemical Equilibrium?

Chemical equilibrium refers to the state of a system in which the concentration of the reactant and the concentration of the products do not change with time, and the system does not display any further change in properties.

It is the state of a reversible reaction where the rate of the forward reaction equals the rate of the reverse reaction. While a reaction is in equilibrium the concentration of the reactants and products are constant.

Therefore, A chemical reaction is at equilibrium. Compared to the rate of the forward reaction, the rate of the reverse reaction is  the same and the reaction continues in both directions and the correct option is option 4.

The ideal gas constant, R has several different values that could be used. Which quantity causes these differences?a. pressure
b. temperature
c. volume
d. moles

Answers

The coorrect answer is option A. The pressure of the gas can cause the ideal gas constant R, to take dfferent values. Because all the other three factors namely, Temperature (T), Volume(V) and the number of moles (n) can change the pressure of a gas. So, I f we change the pressure of the gas alone, we can change its gas constant R value.
The answer is pressure. Pressure is characterized as drive per unit region. It is generally more advantageous to utilize weight instead of constraining to portray the impacts upon liquid conduct. The standard unit for weight is the Pascal, which is a Newton for every square meter.

What is a chemical entity that forms a complex ion around a central atom?

A coordination complex consists of a central atom or Jon, which usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligand or complexing agents

The basic points in Lewis and Langmuir theory of electrovalency

Answers

The correct answer for the question that is being presented above is this one: "Electrovalency is characterized with the transferring of one or more electrons from one atom to another together with the formation of ions and as well as the number of positive and negative charges. 

The Lewis and Langmuir theory of electrovalency (and as well as Kossel's) is dealing with Ionic bonds. 

Lewis: electron-pair sharing, octet rule, Lewis Symbols or StructureLangmuir: introduced term "covalent" bond, and popularized Lewis's ideas

The Lewis-Langmuir electron-pair or covalent bond is referred as the homopolar bond, where the complete transfer of electrons give rise to ionic, or electrovalent bond (1) through attraction of opposite charges.

Which solution reacts with LiOH(aq) to produce a salt and water?(1) KCl(aq) (2) CaO(aq) (3)NaOH(aq) (4)H2SO4(aq)

Answers

The answer is (4) H2SO4. The LiOH(aq) is a kind of base. The solution which can react with base and produce a salt and water is acid. Among the choices, only H2SO4 is acid.

Which of these statements is true about reaction rates is accurate? a. all chemical reactions occur at a slow rate.
b. all chemical reactions at the same rate.
c. all chemical reactions at a fast rate.
d. all chemical reactions occur at different rates.

Answers

all chemical reactions occur at different rates due to difference in their kinetic energy option D is right hope this helps

Hi there!

Analyzing This Question Correctly We Can conclude thatthe Most accurate  and correct answer is D.

We Can conclude to this By using The collision theory.The Collision Theory states that in order for a reaction to proceed, the reactant particles must collide.  The more successful collisions there are per unit of time, the faster the reaction will be.

Factors which can affect the rate of a reaction include:

⚛ concentration

⚛ temperature

⚛ particle size

⚛ catalysts

⚛ stirring rate

⚛ light intensity

For Example, By adding less Baking soda to Vinegar the less Co2(Carbon Dioxide) Will Be created.

By Adding More Baking Soda to vinegar, more Co2 Will Be created.

Hope This Has helped
