It may seem counter-intuitive but breaking bonds absorb energy. In simplicity, the reason is energy is required to overcome the electrostatic attractions between bonded atoms. Bonded atoms are attracted to each other by interactions between the electron cloud of one atom and the positive (proton filled) nucleus of the other atom.

What type of energy does breaking bonds release?
Breaking bonds releases potential energy stored in the chemical bonds. This potential energy can be released as kinetic energy or in the form of heat depending on the reaction.
When covalent bonds are broken energy is released?
Breaking covalent bonds requires input of energy, not the release of energy. When covalent bonds are broken, energy is absorbed by the molecules involved in the process.
What helps weaken these bonds so energy can be released and then later help reform them?
Chemical reactions weaken bonds by absorbing energy to break them, and release energy when forming new bonds. This process involves breaking existing chemical bonds through input of energy, and then forming new bonds that release energy. This cycle of bond breaking and bond formation allows for energy to be absorbed and released in a controlled manner.
What is the role of energy in forming bonds and breaking bonds?
The enthalpy change associated with a reaction = sum of (energies of bonds broken) - sum of (energies of bonds formed). Thus, if this value is net negative, the reaction is exothermic; the products are also more stable than the reactants (lower-energy bonds). A positive enthalpy indicates an endothermic reaction.
Does making chemical bonds release or require energy?
Forming chemical bonds releases energy because it involves a decrease in potential energy as atoms move closer together to form more stable configurations. Breaking bonds, on the other hand, requires energy input to overcome the attraction between atoms.
When bonds are broken is energy released or stored?
energy is release by the breaking of bonds
The process of breaking down food to release its energy is called?
The process of breaking down food so we can absorb it is called digestion. Releasing the energy by breaking it down further in our cells is respiration.
What type of energy does breaking bonds release?
Breaking bonds releases potential energy stored in the chemical bonds. This potential energy can be released as kinetic energy or in the form of heat depending on the reaction.
What do chemical bonds have to do with a temperature change?
Chemical bonds store energy, and breaking or forming these bonds can either release or absorb energy, which can lead to a temperature change. When bonds are formed, energy is released, resulting in an exothermic reaction that can increase the temperature of the surroundings. Conversely, breaking bonds requires energy input, resulting in an endothermic reaction that can decrease the temperature of the surroundings.
When covalent bonds are broken energy is released?
Breaking covalent bonds requires input of energy, not the release of energy. When covalent bonds are broken, energy is absorbed by the molecules involved in the process.
What energy represents a release of what binding force?
The energy released during a chemical reaction represents the breaking of bonds between atoms or molecules. This energy is the result of the release of the potential energy stored in these bonds.
What helps weaken these bonds so energy can be released and then later help reform them?
Chemical reactions weaken bonds by absorbing energy to break them, and release energy when forming new bonds. This process involves breaking existing chemical bonds through input of energy, and then forming new bonds that release energy.

Forming chemical bonds releases energy because it involves a decrease in potential energy as atoms move closer together to form more stable configurations. Breaking bonds, on the other hand, requires energy input to overcome the attraction between atoms.
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 would provide the body with most energy?
breaking the bonds in a disaccharide/ polysaccharide
Why do some chemical reactions release heat while others absorb heat?
Chemical reactions release or absorb heat based on whether they release or require energy to break or form bonds between atoms. Reactions that release heat are exothermic, as they release energy, while reactions that absorb heat are endothermic, as they require energy input.
