3. For the n=5 to n=2 transition: E = in nm = in Å = Color of corresponding line in the hydrogen spectrum: b. Calculate the molar concentration of the hydrochloric acid if 35.18 mL of hydrochlo- ric acid was required to neutralize 0.450 g of sodium bicarbonate to a phenolphthalein end point. C. Calculate the mass percent concentration of hydrochloric acid using the molar con- centration calculated in part band assuming the density of the solution is 1.01 g/mL....
The Bohr model can be applied to singly ionized helium He+ (Z = 2). Using this model, consider the series of lines that is produced when the electron makes a transition from higher energy levels into the = 4 level. Some of the lines in this series lie in the visible region of the spectrum (380−750 nm). What are the values of for the energy levels from which the electron makes the transitions corresponding to these lines? We were unable...
The hydrogen spectrum has a red line due to the n=3 to n=2 transition. This line appears at an angle of 65.0 degrees when using a certain diffraction grating. Using the same diffraction grating for the n = 3 to n = 2 transition in ionized helium He^+ what would be the angular location of that line? Assume 1st order spectrum for both.
