While it is almost always called water, the systematic chemical name for H2O is actually 'dihydrogen monoxide'.
— Nomenclature: Binary Molecular Compounds
While changes in concentration or pressure can shift a chemical equilibrium, only a change in temperature will alter the actual value of the equilibrium constant, K.

By calculating a reaction's 'quotient' (Q) at any moment and comparing it to its equilibrium constant (K), chemists can predict the direction the reaction needs to shift to reach equilibrium.
— The Reaction Quotient (Q)
In chemistry, the names of many simple compounds are created by keeping the metal's name and changing the end of the nonmetal's name to '-ide,' turning sodium and chlorine into 'sodium chloride'.
