Calculate the wavelength, in nanometers, of the light emitted by a hydrogen atom when its electron falls from the n = 7 to the n
Gre4nikov [31]

Answer:

The wavelength of the light emitted by a hydrogen atom for the given transition is 2166 nm.

Explanation:

The energy of nth energy levels of the H atom is given as:

E_n = -2.18 \times 10^{-18} \times \frac{1}{n^2} J

Energy of the seventh energy level = E_7

E_7=-2.18 \times 10^{-18} \times \frac{1}{7^2} J

E_7=-2.18 \times 10^{-18} \times \frac{1}{7^2} J=-4.4490\times 10^{-20} J

Energy of the seventh energy level = E_4

E_4=-2.18 \times 10^{-18} \times \frac{1}{4^2} J

E_4=-2.18 \times 10^{-18} \times \frac{1}{16} J=-1.3625\times 10^{-19} J

Energy of the light emitted will be equal to the energy difference of the both levels.

E=E_7-E_4=-4.4490\times 10^{-20} J-(-1.3625\times 10^{-19} J)

E=9.176\times 10^{-20} J

Wavelength corresponding to energy E can be calculated by using Planck's equation:

E=\frac{hc}{\lambda }

\lambda =\frac{hc}{E}=\frac{6.626\times 10^{-34} Js\times 3\times 10^8 m/s}{9.176\times 10^{-20}  J}=2.166\times 10^{-6} m=2166 nm

The wavelength of the light emitted by a hydrogen atom for the given transition is 2166 nm.

How many grams are in 2.40 mol of sodium chloride (NaCl)
RideAnS [48]
You find the molar mass of NaCl first, by adding the weight of both to get 58.44g. 
Then you set up the equation with what is given:
2.4mol NaCl and multiply it by 58.44g NaCl to get your answer= 140.256g
