which best describes exothermic chemical reactions?
Hi there: As I am not a studying chemist, I did not want to mince my words therefore, I have taken the liberty of copying the following information: Overview In an exothermic reaction, the total energy absorbed in bond breaking is less than the total energy released in bond making. In other words, the energy needed for the reaction to occur is less than the total energy provided. As a result of this, the extra energy is released, usually in the form of heat. When using a calorimeter, the change in heat of the calorimeter is equal to the opposite of the change in heat of the system. This means that when the medium in which the reaction is taking place gains heat, the reaction is exothermic. The absolute amount of energy in a chemical system is extremely difficult to measure or calculate. The
