WebEnergy is absorbed to break bonds. Bond-breaking is an endothermic process.. Energy is released when new bonds form. Bond-making is an exothermic process.. Whether a … WebIn any chemical reaction, chemical bonds are either broken or formed. And the rule of thumb is "When chemical bonds are formed, heat is released, and when chemical bonds are broken, heat is absorbed."Molecules inherently want to stay together, so formation of chemical bonds between molecules requires less energy as compared to breaking …

Endothermic vs. exothermic reactions (article) Khan Academy
WebDehydration synthesis reactions build molecules up and generally require energy, while hydrolysis reactions break molecules down and generally release energy. Carbohydrates, proteins, and nucleic acids are built up and broken down via these types of reactions, although the monomers involved are different in each case. WebAug 4, 2008 · Best Answer. Copy. It may seem counter-intuitive but breaking bonds absorb energy. In simplicity, the reason is energy is required to overcome the electrostatic … WebMay 13, 2024 · When a tube inside the pack is broken, it releases a chemical that reacts with water inside the pack. This reaction absorbs heat energy and quickly cools down the contents of the pack. Figure 2.9. 4: This pack gets cold due to an endergonic reaction. Many other chemical processes involve endergonic reactions. magnolia shiplap chalk paint wax
