Skeletal structural formula of Vitamin B 12.Many organic molecules are too complicated to be specified by a molecular formula.. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are connected to one another.

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.

Ca 2 Al(OH) 6 (Cl) · 2 H 2 O. can be also written in cement chemist notation as: [1] 3CaO·Al 2 O 3 ·CaCl 2 · 10 H 2 O. Friedel's salt is formed in cements initially rich in tri-calcium aluminate (C 3 A). Free-chloride ions directly bind with the AFm hydrates (C 4 AH 13 and its derivatives) to form Friedel's salt.
Ho(OH) 3 + 3 H + → Ho 3+ + 3 H 2 O Holmium(III) hydroxide undergoes thermal decomposition to HoO(OH) at elevated temperatures. Further decomposition at higher temperatures produces Ho 2 O 3 .

The formula, Cu 2 CO 3 (OH) 2 shows that it is halfway between copper carbonate and copper hydroxide. Indeed, in the past the formula was written as CuCO 3 ·Cu(OH) 2. The crystal structure is made up of copper, carbonate and hydroxide ions. [37] The mineral atacamite is an example of a basic chloride. It has the formula, Cu 2 Cl(OH) 3.
