If there is no change in concentrations, why is the equilibrium state considered dynamic?

Chemistry

This condition is not static and is dynamic, because both the forward and reverse reactions are still occurring with the same rate and no macroscopic change is observed.

<h3>What is chemical equilibrium and example?</h3>

Chemical equilibrium is a state during a reversible chemical reaction where there is no net change in the quantities of reactants and products. When a chemical reaction is reversible, the reactants from the initial reaction are created from the products as soon as they are generated.

When the rates of the forward and reverse reactions are equal, a reaction is said to be in chemical equilibrium. All around you, there are numerous instances of chemical balance. An instance would be a bottle of effervescent refreshing drink. The liquid in the container has carbon dioxide (CO2) dissolved in it.

For the reaction 2A + 4B ----&gt; 2C + 2D, at a particular instant in time, the rate of the reaction is 0.0352 M/s. What is the
viva [34]

Explanation:

The given chemical equation is:

2A + 4B -> 2C + 2D

The rate of the reaction is 0.0352 M/s.

During the course of the reaction, the rate of reactants decreases, and the rate of products increases.

The rate of disappearance of B is shown below:

rate=-\frac{1}{4} \frac{d[B]}{dt}

So, rate of change of B is :

rate of change of B =- rate * 4\\=-0.0352 M/s * 4\\=-0.1408M/s\\\\=-0.141M/s

Option C.

Please help! I have no idea what a galactic symbol is. It says it on one of my science assignments and I'm confused. All I know
Ilya [14]
Hey, its alright bro! I gotchu.

Im pretty sure the galactic symbol is the same reference to the symbol of the element on the periodic table.
For an example (Hydrogen) is H 
So if im correct im pretty sure its referring to the symbols for each element

Hopefully this helps

Which pair of elements will form a covalent bond?
Dominik [7]

Answer: Option (A) is the correct answer.

Explanation:

A covalent bond is formed when there occurs sharing of electrons between atoms.

For example, in hydrogen atom there is one electron in its orbit and in a chlorine atom there is 7 valence electron. So, in order to attain stability both hydrogen and chlorine share electrons when they come close to each other.

Whereas except hydrogen and chlorine rest of the given atoms will form ionic bond, that is, bond formed by transfer of electrons.

Thus, we can conclude that a pair of hydrogen and chlorine will form a covalent bond.

4. ¿Cuál es la resistencia de un alambre de
Artemon [7]

Answer:

R=0.0438 Ω

Explicación:

1) Hallar el área o sección del conductor de cobre, usando esta fórmula:

                                      A=π.r² (Pi x radio al cuadrado)

Debido a que conocemos el diámetro (1.5mm) su radio es la mitad de esto es decir 0.75mm, y lo sustituimos en la fórmula:

                                      A=π.(0.75mm)²

                                      A=π(0.5625mm²)

                                      A=1.7671mm²

2) La resistividad del cobre es: rho = 0,0172 y la incluimos en la fórmula siguiente:

                                      R=p  

                                      R=0,0172Ω  x  

Simplificamos:

R=

El resultado es:

R=0.0438 Ω
