So how do we know something is there? See for yourself. Heat Up to Some Cool Reactions All chemical reactions have one thing in common: temperature change. Learn the difference between chemical ...

A change is called irreversible if it cannot be changed back again. Many chemical reactions are irreversible. In a chemical reaction, new materials are always formed. Sometimes these new materials ...

"This process, known as electrocatalysis, also plays a key role in clean energy production." Researchers pioneer breakthrough ...

Students will be able to explain that if two substances cause turn a pH indicator different colors, they must be different substances. Students will be able to explain that the color that a substance ...

The technology, called Single-Molecule Atomic-Resolution Time-resolved Electron Microscopy (SMART-EM for short), lets ...

The Chem-E-Car competition races cars which are only powered by chemical reactions. The goal is to come up with an elegant solution – you can’t simply jettison matter out the back as the ...

Scientists at Oak Ridge National Laboratory have developed a method that can track chemical changes in molten salt ... gas ...

and includes reactions may be activated by heat, light, electrical, or chemical energy. Because of this broad remit, CRE is interested in intricate biochemical pathways, pollution remediation, and the ...

Atoms are rearranged during a chemical reaction, but the number of atoms does not change. Evidence of chemical reactions includes a large temperature change, bubbles, or a colour change.

A common mineral, α-alumina, found abundantly in Earth's crust, may have played a critical role in initiating the chemical reactions necessary for life to begin. This exciting discovery ...
