NettetThis neutralization reaction will be equal to 56.2 kilo joules and mole of C l. This 56.2 kilo joules is what it is producing. For a foul mole, it will produce 0.2248 kilo joule which can be converted into joule by 1000 point. This is the value that we will have here, which is 22224.8 joule of heat released. I hope you understand the whole concept. NettetWhen a chemical reaction occurs, molecular bonds are broken and other bonds are formed to make different molecules. For example, the bonds of two water molecules are broken to form hydrogen and oxygen. (1) 2 H 2 O → 2 H 2 + O 2. Energy is always required to break a bond, which is known as bond energy.
