Every chemical reaction involves a change in energy because different substances hold different amounts of energy. During the reaction, bonds inside the substances that are reacting together must ...

This attraction pulls the atoms together and the electrons are shared by both atoms. The atoms bond because there is a strong enough attraction in both directions and room for the electrons in the ...

If they collide with enough energy, bonds can break and new bonds can form in a chemical reaction. The reactants just sit there until energy is added with the flame. The added energy is enough to make ...

cells release the energy stored in their food molecules through a series of oxidation reactions. Oxidation describes a type of chemical reaction in which electrons are transferred from one ...

In contrast, many microorganisms can generate energy by performing chemical reactions that convert compounds to different chemical forms, and release energy in the process. These are known as ...
