  2. Carbonic acid - Wikipedia

    en.wikipedia.org/wiki/Carbonic_acid

    Carbonic acid is a chemical compound with the chemical formula H 2 C O 3. The molecule rapidly converts to water and carbon dioxide in the presence of water. However, in the absence of water, it is quite stable at room temperature .

  3. UNIFAC - Wikipedia

    en.wikipedia.org/wiki/UNIFAC

    The equation for the group interaction parameter can be simplified to the following: Ψ m n = exp ⁡ − a m n T . {\displaystyle \Psi _{mn}=\exp {\frac {-a_{mn}}{T}}.} Thus a m n {\displaystyle a_{mn}} still represents the net energy of interaction between groups m {\displaystyle m} and n {\displaystyle n} , but has the somewhat unusual units ...

  4. Bicarbonate - Wikipedia

    en.wikipedia.org/wiki/Bicarbonate

    It is isoelectronic with nitric acid HNO 3. The bicarbonate ion carries a negative one formal charge and is an amphiprotic species which has both acidic and basic properties. It is both the conjugate base of carbonic acid H 2 CO 3; and the conjugate acid of CO 2− 3, the carbonate ion, as shown by these equilibrium reactions: CO 2− 3 + 2 H 2 ...

    en.wikipedia.org/wiki/Chemical_formula

    A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs.

  7. Orthocarbonic acid - Wikipedia

    en.wikipedia.org/wiki/Orthocarbonic_acid

    Orthocarbonic acid is highly unstable. Calculations show that it decomposes into carbonic acid and water: [2] [3] H 4 CO 4 → H 2 CO 3 + H 2 O. Orthocarbonic acid is one of the group of ortho acids that have the general structure of RC(OH) 3. The term ortho acid is also used to refer to the most hydroxylated acid in a set of oxoacids.

  9. Formula - Wikipedia

    en.wikipedia.org/wiki/Formula

    A molecular formula enumerates the number of atoms to reflect those in the molecule, so that the molecular formula for glucose is C 6 H 12 O 6 rather than the glucose empirical formula, which is CH 2 O. Except for the very simple substances, molecular chemical formulas generally lack needed structural information, and might even be ambiguous in ...
