One series of lines in the hydrogen spectrum is caused by emission of energy accompanying the fall of an electron from outer shells to the fourth shell. The lines can be calculated using the Balmer-Rydberg equation where nf = 4, R∞ = 1.097 × 10-2 nm-l, and ni is an integer greater than 4. Calculate the wavelengths in nanometers and energies in kilojoules per mole (each to 3 sig. figs.) of the first lines in the series. In what region of the electromagnetic spectrum do they fall?

When a chemist collects hydrogen gas over water, she ends up with a mixture of hydrogen and water vapor in her collecting bottle if the pressure in the collecting bottle is 97.1 kilopascals and the vapor pressure of the water is 3 2 kilopascals, what is the partial pressure of the hydrogen?
