Question

What happens to chemical bonds in chemical reactions?

Answer 1

We have to know that the chemical bonds are formed between molecules that are held by covalent bonds. Breaking or making of bonds is what happens in a chemical reaction. But the energy during this chemical reaction remains conserved; refer to the law of conservation of energy and mass.

Complete answer:
We need to remember that the bonds that keep molecules together break apart and form new bonds during chemical reactions, rearranging atoms into different substances. Each bond takes a distinct amount of energy to either break or form; the reaction does not take place without this energy, and the reactants stay as they were. A chemical bond is a permanent attraction that allows the creation of chemical compounds between atoms, ions or molecules. The bond can result from the electrostatic force of attraction as in ionic bonds, or from the sharing of electrons as in covalent bonds, between oppositely charged ions. There are many other kinds of chemical bonds which account for the formation of molecules. The different chemical bonds can be covalent bond, hydrogen bond, metallic bond, vanderwaal forces and many others. Covalent bond is formed when atoms share electrons and they therefore produce a stable molecule by them. Metallic bond occurs between two metals. Since metals are good conductors of heat and electricity, the electrons in the metal can be moved easily between the atoms. In a chemical reaction, the energy is conserved; it is neither created nor destroyed.

Note:
We need to know that during a chemical reaction, the bonds which hold molecules together break apart and new bonds are formed by rearranging the atoms into different substances. Each breaking or making of a bond requires certain energy and that energy is conserved in a chemical reaction.
