You might see a different value, if you look in a different textbook. However, we're gonna go with 348 kilojoules per mole for our calculation. And we're gonna multiply this by one mole of carbon-carbon single bonds. baker brian d md

"Web- 2 Bonds are formed, NaCl is formed, and energy is produced in the NaCl solution. And the energy from the formation of the bonds, is transferred into the NaCl solution causing the temperature of it to increase - 3 Some heat transfers from the solution, into the surrounding environment. And is it only stage 3 that causes it to be exothermic? " - Forming a bond exothermic

WebExothermic reactions are accompanied by an increase in temperature of the reaction mixture. Chemical reactions that absorb (or use) energy overall are called endothermic. In endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products. WebExothermic: Bond-breaking is said to be endothermic because energy is consumed to create bonds and released when bonds are broken. And the process of bond formation is usually an exothermic process. The presence of bonds is due to the bonded atoms' lower energy state than independent atoms. As a result, heat should be discharged to reduce ...
