In a chemical reaction, new materials are always formed. Sometimes these new materials are useful to us. Irreversible changes are permanent. They cannot be undone. For example, you cannot change a ...

Chemical reactivity is a fundamental concept in chemistry that describes how substances interact and transform during chemical reactions. Density Functional Theory (DFT) is a computational quantum ...

When the solvent evaporates, the phosphorous combines with oxygen in an exothermic reaction. The demonstration shown in this video is very dangerous. Do not attempt to perform this demonstration. The ...

Depending on the process, further particle growth involves condensation (transition from gaseous into liquid aggregate state), chemical reaction(s) on the particle surface and/or coagulation processes ...
