In one word 'ENERGY'.
The energy may be provided by heat, light, or sound, or by other chemicals.
The energy (heat) that is used to break bonds is ENDOTHERMIC.
The energy released on bond formation is EXOTHERMIC.

What changes do chemical reactions involve in chemical bonds that join atoms in compounds?
The bonds in a molecule can break and atoms can bond with other atoms.
What structures break in reactants?
These structures are bonds. 100% positive.
Is melting point a periodic property?
A melting point is a periodic property. Melting point is basically the amount of energy required to break chemical bonds. The more energy required, the stronger the bonds and the higher the melting point. For example, Since Ionic bonds have a transfer of electrons, it requires a lot of energy to break the bonds and has a higher melting point.
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.
Which of these can sometimes break the chemical bonds of atoms?
heat
The energy required to break the bonds in 1 mol of a chemical compound?
bond energy
What happens to atoms during chemical changes?
Chemical changes involve breaking and forming of bonds between atoms. Chemical energy is required to break bonds. The formation of new bonds releases energy.
Which of these can sometimes break the chemical bonds of atoms-?
Heat can sometimes break the chemical bonds of atoms.
What changes do chemical reactions involve in chemical bonds that join atoms in compounds?
The bonds in a molecule can break and atoms can bond with other atoms.
When bonds break and new bonds form?
When bonds break and new bonds form, a chemical reaction has taken place.
What can break chemical bonds of atoms?
A chemical reaction can break the chemical bonds that hold atoms together. A change in temperature can also do it, as can an electric current.
What structures break in reactants?
These structures are bonds. 100% positive.
What happens to chemical bonds in a molecule during a chemical reaction?
The existing chemical bonds break and new bonds are created to give products.
What happends when bonds break and new bonds form?
A new molecule is formed after a chemical reaction.
What do most chemical reaction do?
do not break bonds
Is melting point a periodic property?
A melting point is a periodic property. Melting point is basically the amount of energy required to break chemical bonds. The more energy required, the stronger the bonds and the higher the melting point. For example, Since Ionic bonds have a transfer of electrons, it requires a lot of energy to break the bonds and has a higher melting point.
Is a physical change what happens when chemical bonds break and new bonds form?
NO, that's an example of a CHEMICAL change
