For the following chemical reactions, calculate the total energy released and absorbed in order to determine whether the chemical reactions are endothermic or exothermic. Drawing out structural formulae and using the table below will help. Remember that when bonds are formed, energy is released, and when bonds are broken, energy is absorbed.
