A) use the bohr model from your text to calculate the expected emission lines from the h atom for the first four members in the series of emission lineslisted below. give the photon energies and wavelengths (nm) for each emission line. series n(initial) n (final) lymanseries 2, 3, 4,5 1 balmerseries 3, 4, 5,6 2 paschenseries 4, 5, 6,7 3 brackett series 5, 6,7,8 4 b)in what wavelength region (visible, ultraviolet, infrared, etc…) do the first emission lines from each of the above series fall

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.

Iam in desperate need of with this !
