WebChemical 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. Exothermic reactions are accompanied by an increase in temperature of the reaction mixture. WebIndicate whether each of the following is a characteristic of an endothermic or an exothermic chemical reaction. a. There is more energy stored in product molecule bonds than in reactant molecule bonds. b. The energy required to break bonds in the reactants is less than the energy released by bond formation in the products. Solution introducing the positions for viola pdf https://doble36.com
