When chemical bonds form
Chemical energy is released during a chemical reaction.

When chemical bonds form
During a chemical reaction, energy is either absorbed or released. If energy is released, it is usually in the form of heat. If energy is absorbed, the reaction requires an external energy source to proceed.
Energy can either decrease or increase during a chemical reaction depending on whether it is an exothermic reaction (energy is released) or an endothermic reaction (energy is absorbed). In an exothermic reaction, energy is released in the form of heat, and in an endothermic reaction, energy is absorbed from the surroundings.
The temperature increases when energy is released during a chemical reaction.
Depending on the particular chemical reaction, energy may be either released or absorbed.
Chemical potential energy is the energy stored in the chemical bonds of a substance that can be released during a chemical reaction.
In a chemical change, energy is either absorbed or released. When bonds are broken, energy is absorbed (endothermic reaction), and when bonds are formed, energy is released (exothermic reaction). Overall, the total energy of the system may change during a chemical reaction.

Yes.
when a chemical change occurs, chemical bonds are broken up
