Answer:

Mf = MiVi / Vf

Explanation:

To obtain the answer to the question given, let us obtain the equation for the final concentration.

This can be obtained from the dilution equation as shown below :

MiVi = MfVf

Mi is the initial concentration

Mf is the final concentration

Vi is the initial volume

Vf is the final volume.

Making Mf the subject of the above equation, we can obtain the equation which can be used to calculate the final concentration. This is illustrated below:

MiVi = MfVf

Divide both side by Vf

Mf = MiVi / Vf

Therefore, the equation which can be used to calculate the final concentration is Mf = MiVi / Vf

Can someone please please help me out ?
GarryVolchara [31]

Answer:

4.823 x 10^-19 J

Explanation:

Energy is calculated by E = hv where h - Planck's constant in joule.s

v - frequency.

in this particular question the wave length is 4.12 x 10^-7 m. to exhaustively use this we need a relation between wave length & frequency. c=wv where C is approximately 3 x 10^8m/s

-v = c/w = 3x10^8m/s / 4.12 x 10^-7m = 7.28 x 10^14 Hz or 1/sec

now we can simply use Planck's constant in E=hv =

(6.626 x 10^-34) x (7.28 x 10^14Hz) = 4.823 x 10^-19 J.

What happens to a glass of water as the average molecular kinetic energy of the water molecules increases?
trasher [3.6K]
"The water becomes warmer."
<u>Remember</u>: Kinetic energy means how much, on average, a molecule is moving around. This is directly translated into heat. Therefore, the higher the kinetic energy, the more heat produced.

Which of the following statements is true? A) If Q &lt; K, it means the forward reaction will proceed to form more products. B)
GuDViN [60]

Hey there!:

If Q = K, it means the reaction is at equilibrium.

The correct statments are as follows:

A. If Q < K, it means the forward reaction will proceed to form more products.

B. If Q > K, it means the backward reaction will proceed to form more reactants.

The statement C is true.

Hope this helps!
