The energy e of the electron in a hydrogen atom can be calculated from the bohr formula:

e= -ry/n^2

in this equation ry stands for the rydberg energy, and n stands for the principal quantum number of the orbital that holds the electron.

calculate the wavelength of the line in the absorption line spectrum of hydrogen caused by the transition of the electron from an orbital with n=2 to an orbital with n=3.

The wavelength of the line in the absorption line spectrum of hydrogen caused by transition is 657.1 nm.

Explanation:

Energy of the electron in a hydrogen atom in nth shell:

Energy of an electron in n = 2:

Energy of an electron in n = 3:

Energy difference in between both the shells:

:

=

The wavelength of the line in the absorption line spectrum of hydrogen caused by transition is 657.1 nm.

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .

it is a solid
