Spectral lines of Hand Bohr model: A sample of hydrogen gas produces the emission lines labeled A-D, all of which result from electronic transitions down to the 2nd energy level (n=2) from higher energy levels.
Which of the following is true regarding these electronic transitions?
Emission Spectrum of Hydrogen
Аз с D
increasing wavelength
Spectral line C is due to the electronic transition from n = 6 to n =2, which is the highest energy transition
The Spectral line D is due to the electronic transition from n = 3 to n=2, and it is the transition with the lowest frequency compared to the other transitions.
The frequency of the spectral line due to the electronic transition from n = 5 to n=2 is lower than the electronic transition from n= 4 to n=2.
All of these transitions are in the Infrared region of the electromagnetic spectrum
A Moving to the next question prevents changes to this answer.

Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, consult a reference and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. pbutane = atmosphere - pwater use the following combined gas law formula and compute the volume that the butane sample will occupy at stp. (hint: convert both temperatures to kelvin.) pbutane x voriginal = pstandard x vfinal troom tstandard use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. grams of butane you used “x” grams of butane ml of butane corrected to stp = 22,400 ml compute the theoretical molar mass of butane based on its formula and the atomic masses on the periodic table. compare your experimental results from #3 to the theoretical value of #4, computing a percent error of your findings using this formula: % error = measured value - accepted value x 100 accepted value use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. need asap
