chemical reactions
Substances becoming new
Chemical reactions are processes in which substances transform into different substances through the rearrangement of atoms.
Bonds between atoms break and reform in new configurations, producing products with different properties than the starting materials.
The rusting of iron is a slow chemical reaction.
Chemical reactions power everything from metabolism to combustion to the setting of concrete.
