What kind of reaction is the amount of energy needed to break the original bonds is less than the energy released when new bonds form?
What type of reaction requires less energy to break the original bonds than the energy released when new bonds form?
What bonds of the reactants are broken in this reaction?
Energy is the key for any reaction to take place. To break the bonds of a substance, a fixed amount of energy is required which is called bond energy. For some substances the bond energy is low and they do not require external energy and start reaction on their on there own whereas for some substances we have to provide external energy for the reaction to take place.
What happens to energy during a chemical reaction?
During a chemical reaction, energy gets used to break the existing bonds in order to create new bonds.
What is a chemical reaction that harvests energy when chemical bonds are broken?
It always takes energy to break chemical bonds. Similarly, energy is released when bonds are formed. When the new bonds formed are weaker than the old ones broken, the reaction consumes energy and is called endothermic.
Does it take energy to make bonds?
Yes, a stronger bond requires more energy to break, and also releases more energy when it is made. In a chemical reaction, if you are breaking strong bonds, and only making weak ones, the reaction will require a lot of energy (endothermic). If instead you are breaking weak bonds and making very strong ones in the products, the reaction will release energy (exothermic).

What can a reaction occurs to added to break bonds?
Any chemical reaction need an activation energy.
Why do Magnesium and Hydrochloric acid have an exothermic reaction?
It will as the energy required to break the bonds is more than the energy required to make the new bonds.

It always takes energy to break chemical bonds. Similarly, energy is released when bonds are formed. When the new bonds formed are weaker than the old ones broken, the reaction consumes energy and is called endothermic.
What is endothermic and exothermic?
Exothermic refers to a reaction that produces heat. When you balance the equation the energy released when new bonds are formed is greater than the energy use when bonds are broken. An endothermic reaction takes in heat as it requires more energy to break its bonds than it has from the bonds it creates.
Does it take energy to make bonds?
Yes, a stronger bond requires more energy to break, and also releases more energy when it is made. In a chemical reaction, if you are breaking strong bonds, and only making weak ones, the reaction will require a lot of energy (endothermic). If instead you are breaking weak bonds and making very strong ones in the products, the reaction will release energy (exothermic).
When do reactions that release energy happen?
The release of energy (exothermic reaction) happens when the energy release by forming the products of the reaction is greater than the energy required to break the bonds of the reactants.
Is energy consumed at any time during an exothermic reaction?
Yes, during the time it absorbs energy to break bonds.
What initiates chemical reactions by breaking bonds in the reactants?
That process is called a chemical reaction.
How do you tell endothermic reaction from an exothermic reaction by looking at the chemical equation?
You have to add up the bond energies of all the bonds on the products side and the reactants side. When bonds are formed energy is released. Conversely energy has to be put into a system to break bonds (like smashing a block of ice with a baseball bat) If there is more bond energy on the products side bonds were created (energy was released) which means the reaction is exothermic. If there is more bond energy on the reactants side, bonds were broken (energy put in) and so the reaction is endothermic.
