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...

Chemical energy stored in the reactants is released as heat when the reaction is exothermic. For an exothermic reaction, the enthalpy change for a reaction is negative. Enthalpy, represented as H, is the heat content of a system. As it is a state function, it depends on the state of the system; hence, it is calculated in the form of change in heat content. Heat change, or enthalpy change, is represented as ΔH; ΔH is a measure of the heat...
