A decomposition reaction is the reverse of a synthesis reaction and is a reaction in which a single compound undergoes a reaction that produces two or more simpler substances. Such reactions are generally endothermic since energy is required to break the chemical bonds and separate the constituent elements. Fe 2 O 3 + 3SO 3 → Fe 2 (SO 4) 3; NaCl + AgNO 3 → AgCl + NaNO 3 (NH 4) 2 Cr 2 O 7 → Cr 2 O 3 + 4H 2 O + N 2; Solution. 1) Combustion/Burning Reactions: Reaction of some combustible matters with oxidizing elements like oxygen is called combustion reactions.After these reactions oxidized products are produced. machdevadwAnipandr machdevadwAnipandr 05.06.2016 Science Secondary School Fe (s) + CuSO4 (aq) →FeSO4 (aq) + Cu (s) Identify the type of reaction. a product that is neither.
