Ionization energy calculations

The problems ask to find the ionization energy(kJ/mol) for a chemical process given the process and the wavelength. An example is "N2 + 80.1 (wavelength in nm) -> positive charged N2 + e-" Another is 02 + 99.3 -> positive charged 02 + e-

Chlorine, ozone and ultraviolet light

Describe and compare disinfection using chlorine, ozone and ultraviolet light by listing the advantages and the disadvantages of each disinfectant in a table.

Ionization energy process

The question asks for the ionization energy(kJ/mol) for the following chemical process given the wavelength O + (wavelength) -> O(positively charged) + e(negative charge) Wavelength = 91.2 (nm)

Concentration of atmospheric CO2

If the concentration of atmospheric CO2 were to double from its current value of 330 ppm, what would be the calculated pH of rainwater assuming that CO2 was the only acidic input? Please show step by step.

Atmospheric burden of carbon dioxide

Given that the atmospheric burden of carbon dioxide increases by about 3.8 Gigatonnes annually, calculate the annual increase in its concentration on the ppm scale. Note that the atmospheric mass = 5.1E21g; air's average molar mass = 29.0 g mole-1. Please show step by step.
