In an exothermic reaction is the energy of the products higher or lower than that of the reactants?
In an exothermic reaction the energy of the products is less than that of the reactants.
Contrast endothermic and exothermic reactions?
Endothermic reactions are chemical reactions that use heat as part of the reactant. Heat is absorbed into the reaction in order for it to continue. Exothermic reactions are chemical reactions that release heat as a product of the reaction.
Does an exothermic reaction contain more chemical energy than reactants?
depends , if the reaction is endothermic or exothermic. if the reaction is endothermic , the energy needed to break the bonds is greater than the energy that forms bonds.and to break bonds you need thermal energy , meanwhile forming bonds gives off energy. now if the reaction is exothermic the energy given off the bonds form are greater than the enrgy needed to break them. you know if the reaction is exothermic or endothermic because exothermic have a negitave delta next to d eqn.while endothermic have a positive delta.
How is heat from the sun an exothermic reaction?
Exos= outside , thermos=temperature or heat So within the definition itself it can be known that in exothermic reactions heat is released. In chemical reactions the energy supplied is use in breaking of bonds, but energy is release by making bonds. In exothermic reactions, the energy supplied is sufficient for chemical reaction to occur (to break existing bonds) and the excess energy is given in the form of heat (from making new bonds).If the reaction is exothermic, it means that the total 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 2H2 +O2 ----> 2H20 which is exothermic reaction. Combustion reactions in general are exothermic reactions.
Endothermic and exothermic reaction?
An exothermic reaction releases energy, usually to the surroundings. There is a net loss of energy from the reactants. However, exothermic reactions also need a little energy to get started, but this is less than the eventual amount given out. An endothermic reaction takes in energy, also usually from the surroundings. There is a net gain of energy into the reactions. Again, a little energy is lost, but this is hardly anything compared to the amount taken in.
In an exothermic reaction is the energy of the products higher or lower than that of the reactants?
In an exothermic reaction the energy of the products is less than that of the reactants.
What is an example of an exothermic reaction and why it's an exothermic reaction?
There are so many examples of exothermic reactions that is the reactions in whoch energy is released. All the oxidation reactions are exothermic reactions . similarly hydrogenation of alkenes like ethene,cyclohexene etc. are also exothermic reactions with different energies being released during these reactions. The cause for release of energy during these reactions is simple, if the energy relleased due to formation of new bonds that is the bonds of products is more than the energy consumed for breaking the bonds of reactants then such reactions are exothermic. So, ENTHALPY CHANGE =Bond energy of reactants - Bond energy of Products The amount of energy released is thus dependent on the values of bond energies. For example in case of hydrogenation of cyclohexene, Benzene and Cyclooctene these values are 120 kj/mole, 210 kj/mole and 23 kcal/mole respectively
How can endothermic and exothermic reactions work alike?
Endothermic and exothermic reactions are similar in that both have reactants and products. They are different in that exothermic reactions release energy through reacting and endothermic reactions absorb it.
What is a type of chemical reaction where the energy of the products is less than the energy of the reactants?
When a reaction has products that have a lower temperature than the reactants did, the reaction is endothermic.
What is released by exothermic reactions?
Heat is released by an exothermic reaction. Exothermic means heat releasing.
Contrast endothermic and exothermic reactions?
Endothermic reactions are chemical reactions that use heat as part of the reactant. Heat is absorbed into the reaction in order for it to continue. Exothermic reactions are chemical reactions that release heat as a product of the reaction.
Energy is released by?
Exothermic reactions.
Which type of reaction is the burning of gasoline to release heat energy?
Exothermic reactions release heat into the system, ie. heat is a product of the reaction and thus the products have less energy than the reactants and the change in enthalpy is negative.Exothermic reactions release heat. Like potassium into water
What can an exothermic reaction do?
Exergonic reactions are chemical reactions in which energy is released as heat.
Does an exothermic reaction contain more chemical energy than reactants?

How is energy involved in a chemical reaction?
Activation energy is needed to start a chemical reaction. This energy is used to join the reactants together or break them apart. If a reaction is exothermic then it gives energy out. If it is endo thermic then the reaction takes energy in.
