i was thinking 35 kJ but i feel like im way off lol

1. The Enthalpy of the Reaction is the Enthalpy of Formation of the Products - the Enthalpy of Formation of the Reactants. (It signifies energy released or gained by the during the course of the reaction). Make sure to multiply the number of moles to these numbers

If the enthalpy of reaction is negative it is exothermic (releases heat). If it is positive it is endothermic (gains heat)
