IUPAC nomenclature is used for the naming of chemical compounds, based on their chemical composition and their structure. [1] For example, one can deduce that 1-chloropropane has a Chlorine atom on the first carbon in the 3-carbon propane chain.

The names "caffeine" and "3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione" both signify the same chemical compound. The systematic name encodes the structure and composition of the caffeine molecule in some detail, and provides an unambiguous reference to this compound, whereas the name "caffeine" simply names it.
Co + H 2 SO 4 + 7 H 2 O → CoSO 4 (H 2 O) 7 + H 2 CoO + H 2 SO 4 + 6 H 2 O → CoSO 4 (H 2 O) 7. The heptahydrate is only stable at humidity >70% at room temperature, otherwise it converts to the hexahydrate. [2] The hexahydrate converts to the monohydrate and the anhydrous forms at 100 and 250 °C, respectively. [1] CoSO 4 (H 2 O) 7 → CoSO ...
3 COOH, which is commonly called acetic acid and is also its recommended IUPAC name, but its formal, systematic IUPAC name is ethanoic acid. The IUPAC's rules for naming organic and inorganic compounds are contained in two publications, known as the Blue Book [1] [2] and the Red Book, [3] respectively.
Note that the especially high molar values, as for paraffin, gasoline, water and ammonia, result from calculating specific heats in terms of moles of molecules. If specific heat is expressed per mole of atoms for these substances, none of the constant-volume values exceed, to any large extent, the theoretical Dulong–Petit limit of 25 J⋅mol ...

For example, 10% oleum can also be expressed as H 2 SO 4 ·0.13611SO 3, 1.13611SO 3 ·H 2 O or 102.25% sulfuric acid. The conversion between % acid and % oleum is: % = + % For x = 1 and y = 2 the empirical formula H 2 S 2 O 7 for disulfuric (pyrosulfuric) acid is obtained. Pure disulfuric acid is a solid at room temperature, melting at 36 °C ...
