. "Mole concentration means number of moles per unit volume, also called \"molarity\", and is used in the construction \"mole_concentration_of_X_in_Y\", where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as \"nitrogen\" or a phrase such as \"nox_expressed_as_nitrogen\". The specification of a physical process by the phrase \"due_to_\" process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. \"Chemical destruction\" means the result of all chemical reactions within the medium (here, atmosphere) that remove a certain amount of a particular species from the medium. \"tendency_of_X\" means derivative of X with respect to time. The chemical formula for methane is CH4. Methane is a member of the group of hydrocarbons known as alkanes. There are standard names for the alkane group as well as for some of the individual species."@en . "2015-01-07 16:23:38.0" . "SDN:P07::DWDVJ3B2" . . .
