<h3>Energy of Photons</h3>
The formula for calculating the energy of photons is expressed as:
where
- h is the Plank constant
- c is the speed of light
- λ is the wavelength
Substitute the values into the formula to have:
Hence the energy of the photons is

<u>Answer:</u> The wavelength of light is
<u>Explanation:</u>
To calculate the wavelength of light, we use Rydberg's Equation:
Where,
= Wavelength of radiation
= Rydberg's Constant =
= Higher energy level = 7
= Lower energy level = 2
Putting the values in above equation, we get:
Converting this into nanometers, we use the conversion factor:
So,
Hence, the wavelength of light is
Answer: 5.844 grams of NaCl needed to make solution.
Explanation:
Answer : The concentration of and at equilibrium is, 0.0031 M and 0.0741 M respectively.
Explanation : Given,
Moles of = 0.166 mol
Volume of solution = 2.15 L
First we have to calculate the concentration of
Now we have to calculate the concentration of and at equilibrium.
Initial conc. 0.0772 0 0
At eqm. 0.0772-x x x
The expression for equilibrium constant is:
By solving the term, we get the value of 'x'.
x = 0.0741
Thus,
The concentration of at equilibrium = (0.0772-x) = (0.0772-0.0741) = 0.0031 M
The concentration of at equilibrium = x = 0.0741 M
