Best answer

If the reaction is exothermic,it means that thetotal energy it took to break the bonds is less than the total energy released when forming new bonds– so net energy is released in the form of heat. for example 2 H 2 +O2 —- 2 H 2 0 which is exothermic reaction.

  • Why do exothermic reactions release heat Quizlet?

  • Why do exothermic reactions release heat? Doc Croc. Exothermic reactions convert chemical energy (enthalpy) inside chemical substances into heat energy. The chemical energy decreases, and the heat energy increases (total energy is conserved).

  • Are chemical reactions exothermic or endothermic?

  • Because more energy is released when the products are formed than is used to break up the reactants, this reaction is exothermic, and 螖H for the reaction is negative. In this investigation, you will observe whether energy is absorbed or released in two different chemical reactions and categorize them as exothermic and endothermic.

  • What is the equation for exothermic reaction?

  • Exothermic Reaction An Exothermic reaction is a chemical reaction that involves the release of energy in the form of heat or light. These reactions are the opposite of endothermic reactions and can be expressed in a chemical equation as follows: Reactants 鈫?Products + Energy What is an Exothermic Reaction?

  • How is energy absorbed and released in endothermic reactions?

  • 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. If a chemical reaction absorbs as much energy as it releases, it is called isothermic鈥攖here is no net energy change.
