Compare and contrast synthesis reactions and decomposition reaction
Dafna11 [192]

Answer:

See explanation

Explanation:

Synthesis reaction and decomposition reactions are two opposing processes.

While a synthesis reaction has to do with the formation of a substance from its constituents, decomposition deals with the breakdown of a substance into its constituents.

While decomposition requires energy and is an endothermic process, synthesis is usually an exothermic process in which energy is given off as stable products are formed.
