WebNov 4, 2024 · Associate an endothermic and exothermic chemical reaction with their related energy diagram. Understand how a chemical reaction is related to an energy diagram. Interpret data to determine if an endothermic reaction or an exothermic reaction has occurred. Be able to solve problems using Hess’s Law. WebWith Hess's Law though, it works two ways: 1. You use the molar enthalpies of the products and reactions with the number of molecules in the balanced equation to find the change in enthalpy of the reaction. That's what you were thinking of- subtracting the change of the products from the change of the reactants. 2. canadian cities in transition
