Chemical reactions make new chemicals. Atoms are rearranged during a chemical reaction, but the number of atoms does not change. Evidence of chemical reactions includes a large temperature change ...

Iron oxide, aluminum, and a catalyst are placed in a flowerpot. The reaction is extremely exothermic resulting in molten iron and aluminum dripping into sand below the flowerpot. The demonstration ...

In the reaction, the bonds in the methane and oxygen molecule come apart, the atoms rearrange and then re-bond to form water and carbon dioxide. The little number written at the lower right after an ...

In a nutshell Scientists have developed a powerful new microscope called SMART-EM that can record real-time videos of individual atoms and molecules during chemical reactions, something that was ...

A chemical reaction that's vital to a range of commercial and industrial goods may soon be initiated more effectively and less expensively.

A key objective of ongoing research rooted in molecular physics is to understand and precisely control chemical reactions at ...
