The energy involved in a chemical reaction does not change the actual atoms participating but the bonds between the atoms. Based on this idea, explain how some chemical reactions release energy and some absorb energy. What physical demonstrations might you use to illustrate this concept to your students?

ENERGY FROM CHEMICAL REACTIONS (page 8) Many chemical reactions release energy, while others require energy to happen. These energy changes that occur during chemical reactions are due to changes in bonding between the reactant molecules and product molecules. Breaking bonds between atoms always requires energy, while creating bonds between atoms always releases energy. Analyze each of the two chemical reactions below by calculating the total amount of energy needed to break the bonds in the reactants, the total amount of...

The enthalpy change for a chemical reaction is the sum of the
energy consumed in breaking bonds and the energy released during
bond formation. One way to determine the overall energy change for
a chemical reaction is to apply Hess’s law to add together a group
of reactions which can be arranged such that the chemical
equations, when combined, give the overall equation we are trying
to characterize.
