The Simplified Molecular Input Line Entry System (SMILES) is a specification in the form of a line notation for describing the structure of chemical species using short ASCII strings. SMILES strings can be imported by most molecule editors for conversion back into two-dimensional drawings or three-dimensional models of the molecules.
Richard Witt's book Arithmeticall Questions, published in 1613, was a landmark in the history of compound interest. It was wholly devoted to the subject (previously called anatocism), whereas previous writers had usually treated compound interest briefly in just one chapter in a mathematical textbook. Witt's book gave tables based on 10% (the ...
Different styles of structural formulas may represent aromaticity in different ways, leading to different depictions of the same chemical compound. Another example is formal double bonds where the electron density is spread outside the formal bond, leading to partial double bond character and slow inter-conversion at room temperature. For all ...
Since this example has monthly compounding, the number of compounding periods would be 12. And the time to calculate the amount for one year is 1. A 🟰 $10,000(1 0.05/12)^12 ️1
For example, compound interest on a certificate of deposit generally involves earning a fixed interest rate on an increasingly higher balance as that interest gets credited to your account, and if ...
Hückel's rule is not valid for many compounds containing more than one ring. For example, pyrene and trans-bicalicene contain 16 conjugated electrons (8 bonds), and coronene contains 24 conjugated electrons (12 bonds). Both of these polycyclic molecules are aromatic, even though they fail the 4n + 2 rule. Indeed, Hückel's rule can only be ...
Other examples of inorganic polyprotic acids include anions of sulfuric acid, phosphoric acid and hydrogen sulfide that have lost one or more protons. In organic chemistry and biochemistry, important examples include amino acids and derivatives of citric acid. Although an amphiprotic species must be amphoteric, the converse is not true.
Three modes of ring junction are possible for a bicyclic compound: [3] In spiro compounds, the two rings share only one single atom, the spiro atom, which is usually a quaternary carbon. [4] An example of a spirocyclic compound is the photochromic switch spiropyran. In fused/condensed [5] bicyclic compounds, two rings share two adjacent atoms.
