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 ...

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 ...

Some chemical reactions change temperature, change color, produce a gas, or make a solid from two liquids. Try this reaction and see what it does! Pour 1 tablespoon of hydrogen peroxide into a cup.

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 ...

Scientists at Oak Ridge National Laboratory have developed a method that can track chemical changes in molten salt in real time ... the scientists used argon gas (which alone doesn't cause a reaction) ...

A major scientific breakthrough is set to change the way we make many everyday products—making the process faster, safer, and ...

The race for chemical engineering is quite literally on. Every year, the American Institute of Chemical Engineers (AlChE) brings together hundreds of university students to face-off to design the ...

The ancient reactions Suess is investigating rely on specialized enzymes with clusters of metal atoms. These could provide the key to developing new methods that can extract vast amounts of carbon ...

The discipline of Catalysis and Reaction Engineering (CRE) seeks to control and understand the networks of reactions that occur in ‘reactors’ ranging from cellular compartments up to world-scale ...

A new University of Maryland study has revealed a coordinated dance of microscopic particles—breaking up and clustering back together in just seconds—after receiving electrical and chemical ...
