According to Einstein the energy of photon is given by the equation,
E = hν = h . c/λ
where h is Planck's constant, c is the speed of light, ν is the frequency of light and λ is the wavelength of light.
Given, wavelength = 608 nm = 608 x 10⁻⁹ m
Conversion factor: 1 nm = 10⁻⁹ m
c = 3 x 10⁸ m/s
h = 6.626× 10⁻³⁴ J.s
Substituting the data into the equation we get,
E = h . c/λ
E = 6.626× 10⁻³⁴ J.s x (3 x 10⁸ m/s) / 608 x 10⁻⁹ m
E = 3.27 x 10⁻¹⁹J
3.27 x 10⁻¹⁹J energy must be added to strontium to get it to produce 608 nm wavelength.

Answer:
0.013 moles Cl
Explanation:
Grams --> Moles Divide by Molar Mass
Molar Mass of Chlorine (Cl) is 35.5. This can be found on the Periodic Table.
Set Up: (0.456 g Cl) (1 Cl / 35.5 g)
0.456 g * 1 = 0.456
0.456 / 35.5 = 0.01284507
Round to 0.013
Answer:
solvent (such as water, oil or isopropyl alcohol) is allowed to absorb up the paper strip. ... Different molecules run up the paper at different rates. As a result, components of the solution separate and, in this case, become visible as strips of color on the chromatography paper.
