follow-up: what determines whether or not a reaction generates heat?
In: Chemistry
All chemical reactions involve energy.
1. It **takes energy** to break bonds.
2. Energy **is released** when bonds are formed.
Chemical reactions that release energy are called exothermic. In exothermic reactions, more energy is released when the bonds are formed in the products than is used to break the bonds in the reactants.
The **Law of Conservation of Energy** states that “energy cannot be created or destroyed in a chemical reaction, it can only be transformed from one form to another”. Thus, the excess energy produced is released in the form of heat.
An acid-base reaction is one such exothermic reactions, and thus releases energy in the form of heat
