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 energy released upon bond formation in...
