Molecular Formula: The molecular formula provides insight into the number of elements present in a compound. In molecular formulae, the elements are denoted by their respective symbols (as in the periodic table) and the number of atoms of each element in the molecule is written in subscript. ...
Chemical species were defined as follows: “Chemical individuals are phases which are built in a phase system with at least one independent variation, and which keep observably constant composition during all variations indifferent with respect to the conservation of the phase system” [Wald, 1897,...
