Polyatomic ions are covalent units (molecules) where the total number of protons \(\neq\) to the total number of electrons and they were introduced in section 2.6.4.2. They end in [-ide], [-ate] and [-ite].
19 paź 2022 · Saturated fatty acids are saturated with hydrogens; in other words, the number of hydrogen atoms attached to the carbon skeleton is maximized. Stearic acid is an example of a saturated fatty acid (Figure \(\PageIndex{1}\)).
Stearic acid (/ ˈ s t ɪər ɪ k / STEER-ik, / s t i ˈ ær ɪ k / stee-ARR-ik) is a saturated fatty acid with an 18-carbon chain. [9] The IUPAC name is octadecanoic acid. [9] It is a soft waxy solid with the formula CH 3 (CH 2) 16 CO 2 H. [9] The triglyceride derived from three molecules of stearic acid is called stearin. [9]
Enter the formula of a chemical compound to find the oxidation number of each element. A net ionic charge can be specified at the end of the compound between { and }. For example: ZnCl4{2-} or NH2NH3{+}. Enter just an element symbol to show the common and uncommon oxidation states of the element.
