This is a list of unsolved problems in chemistry. Problems in chemistry are considered unsolved when an expert in the field considers it unsolved or when several experts in the field disagree about a solution to a problem.
Class XI - XII roughly covers the 16-17 age group in the context of Bangladesh. After 10 years of schooling at the primary and secondary level, students who succeed in passing the Secondary School Certificate (SSC) examination have the option of joining a college for a two-year higher secondary education in respective areas of specialization or ...
The assumption that solution properties are independent of nature of solute particles is exact only for ideal solutions, which are solutions that exhibit thermodynamic properties analogous to those of an ideal gas, and is approximate for dilute real solutions. In other words, colligative properties are a set of solution properties that can be ...
Theoretical chemistry requires quantities from core physics, such as time, volume, temperature, and pressure.But the highly quantitative nature of physical chemistry, in a more specialized way than core physics, uses molar amounts of substance rather than simply counting numbers; this leads to the specialized definitions in this article.
Solution may refer to: Solution (chemistry), a mixture where one substance is dissolved in another; Solution (equation), in mathematics Numerical solution, in ...
Solid-phase synthesis offers potential solutions to obviate the need for typical quenching and purification steps often used in synthetic chemistry. In general, a starting molecule is adhered to a solid support (typically an insoluble polymer ), then additional reactions are performed, and the final product is purified and then cleaved from the ...
The equilibrium constant for this reaction at 25 °C is 1.8 x 10 −5, [12] such that the extent of reaction or degree of ionization is quite small. Lewis bases A Lewis base or electron-pair donor is a molecule with one or more high-energy lone pairs of electrons which can be shared with a low-energy vacant orbital in an acceptor molecule to ...
