Does breaking old bonds require energy and forming new bonds release energy?

In order to break a bond, you need to apply more energy than that holding it together.
Energy is released when the bond is broken (the energy that was previously holding the bond together.

∙ 14y agoA bond is formed when electrons enter a special low energy state (a state of negative potential). To break this bond and return the atoms to their original free state energy must be supplied. Energy must be supplied to the system to return the system to a higher energy state (the atomic free state).
One way to conceptualize this is by considering applying energy via heat. Heat causes bonds to stretch and strain as the atoms between which these bonds are formed get "jostled" by the transfer of available kinetic energy (heat). As the heat is increased the jostling increases until the strain is great enough to break the bonds.

∙ 12y agoenergy needed to break a bond is endothermic and its value per mole depends on the type of bond IE its strength
Heat is usually transferred to the object so all its molecules intend to move faster so to break its bond.
The heat amout required usually depend on the mass of the object what bond is it and what is the molecular structure of the object, and also the molecules in it.
Graphite and dimond are both made up of carbon atoms with covalent bond, yet the former is the weakest/most slippery(molecules on the surface is easily broken off) solid made of element and the latter is the strongest solid ever known, so never underestimate the power of molecular structure.
Hydrogen bond, meanwhile, is affected by the activity of hydrogen ions() which is indicated by pH value. Too acidic or basic can cause the bond to break.

Does making chemical bonds release or require energy?
Breaking bonds requires energy.
When chemical bonds form is energy absorbed release?
Bond forming releases energy. Atoms will begin with a high potential energy, and will bond with other atoms to form compounds which have a lower potential energy, and are therefore more stable. Bond breaking takes in energy i.e. energy is required to break bonds.
What is the exothermic reaction in terms of bond breaking and bond forming?
An exothermic reaction is a reaction that happens when energy is release. This means that a bond is being broken. Because the bond is broken, it has undergone an exothermic reaction.
What type of energy does breaking bonds release?
Heat is the most common one
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.

What process of breaking down food to release energy?
The process of breaking down food to release energy is called "Digestion".
Making and breaking molecules in the body require the aid of?
energy
Contrast the forming and breaking of chemical bonds in terms of energy changes?
The formation of chemical bonds releases energy. It is an exothermic process. The breaking of chemical bonds takes energy. It is an endothermic process.
Does starting a car require or release energy?
release energy
How do proteins in your cells access the energy stores in ATP?
Proteins in your cells access the energy stored in ATP by breaking down glucose. ATP will release energy any time the cells need to carry out functions that require energy.
What is an exotherm?
In this process bond breaking always requires energy while bond making always release energy. The balance between these two processes result in two types of reactions exothermic and endothermic reaction. When the energy released by bond forming is greater than the energy consumed by bond breaking there is a net release of chemical energy. This type of reaction is called exothermic reaction+ it is a chemical reaction that releases energy in the form of light or heat.
How is energy released in chemical changes?
Breaking a molecule release energy.
Breaking down food to release its energy?
Metabolism
When bonds are broken is energy released or stored?
energy is release by the breaking of bonds
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.
