Question

What happens to chemical bonds in a chemical reaction?

Answer 1

1. In a chemical compound, the atoms are bonded together by a chemical bond which is formed by the mutual sharing of electrons.
2. In a chemical reaction, the reactant molecules react with each other by gaining energy to form products.
3. Due to the energy, the reactant bonds break down to form a new compound.
4. The bonds that keep molecules together break apart and form new bonds during chemical reactions, rearranging atoms into different substances.
5. 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.
6. Example: Water Formation $2{\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to 2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$
7. 
8. Here old bonds between hydrogen-hydrogen and oxygen-oxygen are broken and new hydrogen-oxygen bonds are formed.
