Concentration of CO2 in the Atmosphere Levels of carbon dioxide (CO2) in the atmosphere are rising rapidly, far above any levels ever before recorded. Levels were around 278 parts per million in 1800, before the Industrial Age, and had never, in the hundreds of thousands of years before that, gone above 300 ppm. Levels are now nearing 400 ppm. Table 1 shows the rapid rise of CO2 concentrations over the last 50 years, also available in CarbonDioxide.1 We can use...

Calculate the wavelength of radiation that would absorb from a
molecule of porphyrin at the highest and lowest occupied energy
levels. Poryphyrin has 22 pi electrons that can be idealized as
particles on a ring with a radius of 0.50nm
g) Assume that the 22 r electrons in free base porphyrin (shown below) may be idealized as particles on a ring of radius 0.50 nm. What wavelength of radiation would it absorb for the excitation from the highest occupied energy...

a) The use of spectrophotometry to scan a solution that contains an organic dye will show which wavelengths in the visible spectrum that organic dye most strongly absorbs. Then, using the relationship between energy and wavelength that you learned in Chapter 6, E = hc/λ you could convert each wavelength to its corresponding energy. If you found that an organic dye compound strongly absorbs at 566 nm , what is the energy that corresponds to the excitation of an electron...

1. in the mercury emission spectrum, three intense emission bands can be observed. in the Bohr model of the atom, each of these bands corresponds to a transition from a particular quantum orbital (energy level)n= 1,2,3 ..... for mercury, what color band corresponds to the largest energy difference between levels and which is the smallest? why is that? 2. is it possible for an atom to absorb a photon of red light and remit a photon of violet light? why?

1. Chapter: 12 Lesson: 6 Question: In 2011, the concentration of CO2 in the atmosphere as measured at the Mauna Loa Observatory exceeded 400 ppm. If the barometric pressure at that time had been 0.977 atm, what was the partial pressure of CO2 in the atmosphere (using 400.0 ppm as the concentration of CO2(g))? A 391 atm B. 5.14x10 atm C. 2.97 10-atm D. 4.00 x 10 atm E. 3.91 x 10 atm
