The resulting liquid is something new, made from the molecules of the original liquids. Not all reactions will bubble and froth, and not all result in a yellow liquid. In general, a chemical reaction happens when different molecules interact causing a chemical change.
When elements react, their atoms join with other atoms to form compounds [compound: A compound is a substance formed by the chemical union (involving bond formation) of two or more elements. ] . Chemical bonds form when this happens, which involves atoms transferring or sharing electrons.ew substances are formed by chemical reactions. When elements react together to form compounds their atoms join to other atoms using chemical bonds. For example, iron and sulfur react together to form a compound called iron sulfide.
