Answer:At equilibrium, the forward and backward reaction rate is the same.

Explanation:The equilibrium counteracts any change in the condition of the reactant or product. The le'chatalier principle highlights three main factors that affect the state of equilibrium. The three factors are: amount of moles, concentration and pressure.If the amount of reactant is increased, the equilibrium will shift to the right in order to create a balance between the forward and backward reaction and vice versa.

Answer:

1- Equilibrium determines the rate of reactants and products at the same time.

General expression for equilibrium:

                                     Reactants⇌ Products

2- At equilibrium, all the reactants and products are constant.

3- At equilibrium forward and reverse reaction does not stop, in fact, it continues at all times.

4- When the concentrations of reactants and products become equal dynamic equilibrium is obtained.

For example:

         A + B ⇌ C + D

In this reaction, if the concentration of reactant  A has increased the equilibrium will shift to the right to form more products.

If the concentration of reactant A has decreased the equilibrium will shift to the left in the backward direction to form reactants.

The temperature in a town started out at 55 degrees. By the end of the day the temperature dropped to -6 degrees.
garik1379 [7]

Answer:

The choice of the answer is fourth option that is -61 degrees.

Therefore the temperature drop is -61°Centigrade.

Explanation:

Given:

The temperature in a town started out at 55 degrees

Start temperature = 55°Centigrade. (Initial temperature)

End of the Day      = -6°Centigrade. (Final temperature)

To Find:

How far did the temperature drop?

Solution:

We will have,

\textrm{Temperature drop}=\textrm{Final temperature}-\textrm{Initial temperature}

Substituting the above values in it we get

\textrm{Temperature drop}=-6-55\\\\\therefore \textrm{Temperature drop}=-61\° centigrade

Therefore the temperature drop is -61°Centigrade.

In the bohr model of the hydrogen atom, how does the radius of the electron’s orbit depend on the principal quantum number?
wolverine [178]
The radius of the electron's or basically the energy level for which the electron is found orbiting the nucleus of he hydrogen atom, as the principal quantum number tells us primarily the energy level that the electron will be found, is it the 1st, 2nd, and 3rd. The other quantum numbers tells us more specifically as per the subshell of the main shell the electron is in, the spin of the electron etc.
