Achieving useful levels of stereoselectivity for all classes of ylide will probably require the engineering of high levels of kinetic selectivity. This fits well with the reaction design — the ...

Esters are formed by the condensation reaction between an alcohol and a carboxylic acid. This is known as esterification. In a condensation reaction, two molecules join and produce a larger ...

Developed by UC Santa Cruz chemists, the low-cost process turns used vegetable oil into biodiesel at a temperature lower than ...

Energy obtained from fusion and fission reactions is based on differences in the nuclear binding energy. The mass of the products of a fusion reaction is smaller than the mass of its reactants. The ...

Production of a gas, color changes, a change in temperature, and the formation of a precipitate are all evidence of a chemical reaction. NGSS 5-PS1-4: Conduct an investigation to determine whether the ...

For a chemical reaction to happen: There are different ways to determine the rate of a reaction. The method chosen usually depends on the reactants and products involved, and how easy it is to ...

Students recognize that a particular color change is a characteristic property of a substance and that a color change can also be used as evidence that a chemical reaction has occurred. Students will ...

Reaction Chemistry & Engineering Communications contain novel scientific work of such importance that rapid publication is desirable. Authors should briefly indicate in a covering letter the reasons ...

In reaction videos, some users captured themselves learning about the young singer’s death in real time. At a time when the cameras are always rolling, it’s not so unusual. By Madison Malone ...

The release of drone footage by the Israel Defence Forces (IDF) of Yahya Sinwar's final moments has provoked a torrent of different views across the Middle East. The video shows the Hamas leader ...
