The abstract may contain the chemical formula which best characterizes the invention.
Such a substance's chemical formula describes the simplest ratio of the number of atoms of the constituent elements. See also stoichiometry.
"It is calculated in practice by summing the atomic weights of the atoms making up the substance's molecular formula. The molecular weight of a hydrogen molecule (chemical formula H2) is 2 (after rounding off); for many complex organic molecules (e.g., proteins, polymers) it may be in the millions."
Glucose and fructose have the same chemical formula but have very different properties.
"Carbon dioxide Inorganic compound, a colourless gas with a faint, sharp odour and a sour taste when dissolved in water, chemical formula CO2."
The chemical formula for water is H2O.
The measurement principle and the crystal-chemical formula method, the cation exchange capacity method and alkyl ammonium method are discussed.
"Methano:l Simplest of the alcohols, chemical formula CH3OH."
When utilizing sodium hydroxide as a catalyst, a side reaction of producing a fatty acid soap (reaction of saponification) is easy to take place as shown in the foregoing chemical formula.
Through increasing knowledge span, extending thought depth, clearing up negative transference with regular psychological tendency, strengthening training for variety of chemical formula, efficiency should be increasing to solve chemical problem.
"Any ligand that can Bind to the metal at two or more points to form a ring structure, more stable than a nonchelated compound of the same general chemical formula, is a chelating agent. The process of Binding to the metal is called chelation."
According to Dantus, the technique can even tell the difference between chemical isomers - chemicals with the same chemical formula but a different arrangement of atoms.
"Nitric acid: Inorganic compound, colourless, fuming, highly corrosive liquid, chemical formula HNO3."
