The core electron (1s) photoelectron spectrum of O2 exhibits two bands at 543.1 eV and 544.2 eV.
The corresponding spectra of F2 and N2 exhibit only one band each, 696.70 eV and 409.9 eV, respectively.
Explain why the O2 spectrum exhibits two bands.

The core electron (1s) photoelectron spectrum of O2 exhibits two bands at 543.1 eV and 544.2 eV. The corresponding spec...
Electron transport chains (ETCs), large proteins through which electrons move, play important roles in two of nature's fundamental processes: (1) the conversion of electromagnetic energy from the Sun into the energy in the chemical bonds in glucose molecules and (2) the conversion of the energy in these glucose molecules into useful forms for metabolic processes, such as muscle contraction, building proteins, and respiration. Respiratory ETCs are located in the inner membranes of mitochondria, the power plants of eukaryotic cells. ETCs...

I apologize for the inconvenience.
I am resubmitting it in two separate images to hopefully
improve the picture quality. Thank you so much.
2.26 Two machines are used for filling plastic bottles with a net volume of 16.0 ounces. The filling processes can be assumed to be normal, with standard deviations of o, = 0.015 and o2 0.018. The quality engineering department suspects that both machines fill to the same net volume, whether or not this volume is 16.0 ounces....
