Ozone (O3) in the stratosphere filters out ultraviolet radiation by absorbing light at a wavelength of 250 nm. What is the energy of a single photon of this radiation (J)? What is the energy of a mole of photons at this wavelength (J mole-1)?

The elements carbon and hydrogen combine to form many different compounds. One of the simplest is called methane, in which there are always four times as many hydrogen particles as carbon particles. Methane is a pure substance because it always has the same composition. However, it is not an element because it can be broken down into simpler substances - carbon and hydrogen.
