Ozone, O3, acts as filter of harmful UV radiation in the stratosphere by absorbing light with a wavelength of 290 nm. The photon at 290 nm causes an O-O bond in O3 to give O2 and O.
a) Draw Lewis resonance structures of Ozone molecule
b) Photons from wavelength 290 nm have sufficient energy for O3 --> O2 + O., but to break O2 requires photons with only wavelength 210 nm. Explain your answer, briefly.
Consider following cell. SCE stands for the saturated calomel reference electrode, which has a fixed potential of 0.244 volt. Pt|VOSO4 (0.0586 M), V2(SO4)3 (0.190 M), HClO4 (0.0100 M) || SCE Calculate the cell potential.
Use the atomic radius (70 pm) and density of neon at 25 °C and 1 atm (0.90 g/mL) to calculate the average density of a neon atom.
