A space gun, sometimes called a Verne gun because of its appearance in From the Earth to the Moon by Jules Verne, is a method of launching an object into...

A chemical oxygen generator is a device that releases oxygen via a chemical reaction. The oxygen source is usually an inorganic superoxide, chlorate,...

A chemical element is a chemical substance that cannot be broken down into other substances by chemical reactions. The basic particle that constitutes...

It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and...

A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. When chemical reactions occur...

scientific sense, a chemical process is a method or means of somehow changing one or more chemicals or chemical compounds. Such a chemical process can occur...

The chemical industry comprises the companies and other organizations that develop and produce industrial, specialty and other chemicals. Central to the...
