The first step in the formation of ozone in the upper atmosphere occurs when O2 molecules absorb UV radiation with a wavelength of about 242 nm. Calculate the energy of a photon of 242 nm radiation (E = hv, h = 6.626 x 10 -34 J*s) Light from distant stars is very weak, and astronomers often need to detect just a few photons. What is the total energy of 23 photons having a wavelength of 575 nm? (E = nhv)

lon ci( Ch ioI Part D: 1. Ozone absorbs ultraviolet light in the upper atmosphere thus protecting us from sunburn. Down at ground level however, ozone is a pollutant which can damage your lungs when you breathe it in. The damage is a result of its great reactivity. Draw the two resonance structures possible for ozone (O3) and indicate any nonzero formal charges that are present. Use the resonance structures to explain the great reactivity of ozone. Cl Cl Ic

05 Question (4 points) When a hydrogen atom absorbs a photon of electromagnetic radiation (EMR), the internal energy of the atom increases and one or more electrons may be energized into an excited state. The release of this extra energy as the excited state electron transitions back to a lower energy state results in the emission of a photon. These energy changes are responsible for the emission spectrum of hydrogen (shown below) and are described by the Bohr equation. AE...
