Lesson 8: Modeling A Chemical Reaction

The Law of Conservation of Energy states that energy is neither created nor destroyed in any chemical reaction. Thus, we can determine if a chemical reaction is endothermic or exothermic by quantifying both the amount of energy transferred from the surroundings into the system to break bonds, and the amount of energy released from the system back into the surroundings when bonds are formed.
