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 ...

Chemical reactions make new chemicals. Atoms are rearranged during a chemical reaction, but the number of atoms does not change. A catalyst is a substance that speeds up a chemical reaction.

A Northwestern University-led international team of scientists has, for the first time, directly observed catalysis in-action ...

Students recognize that a particular color change is a characteristic property of a substance and that a color change can also be used as evidence that a chemical reaction has occurred. Students will ...

To help find solutions to the planet's climate crisis, MIT Associate Professor Daniel Suess is looking to Earth's ancient ...

A new study from Cardiff and Bristol universities makes it possible to visualise chemical reactions involving small molecules, using software. Computer simulations ...

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

In simpler terms, if the material holding the metal atom is good at pulling in electrons, the reaction works better. Even ...

This module teaches fundamentals of pericyclic reactions using examples of biocatalysis, biomimetic catalysis, and natural product total synthesis. After completion, students should be able to ...
