Match the chemical reactions. 1. molecules rearrange and form new molecules decomposition 2. simultaneous decomposition and synthesis exchange 3. bonds broken and elements released synthesis 4. molecules formed from components reversible

During chemical reactions the bonds between atoms break and new bonds form. Energy must be absorbed to break a bond, so breaking bonds is endothermic. Making new bonds is exothermic because energy is released.
