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.

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 ...

Students explore the concept that chemical reactions involve the breaking of bonds between atoms in the reactants, and the rearrangement and rebonding of these atoms to make the products. Students ...

Named reactions have a critical place in the history and development of organic chemistry. They help chemists clearly and quickly communicate about complicated transformations, and they honor key ...

Reaction Chemistry & Engineering Communications contain novel scientific work of such importance that rapid publication is desirable. Authors should briefly indicate in a covering letter the reasons ...
