chemical energy, Energy stored in the bonds ofchemical compounds. Chemical energy may be released during achemical reaction, often in the form of heat; such reactions are calledexothermic. Reactions that require an input ofheatto proceed may store some of that energy as chemical energy in newly...
Chemical Energy Facts The energy that results during a chemical reaction is called chemical energy. It is a type of potential energy. Chemical energy is stored within the bonds of the atoms and molecules that make up a substance. Once chemical energy is released from a substance, the substance...
chemistry, thesciencethat deals with the properties,composition, and structure of substances (defined as elements and compounds), the transformations they undergo, and theenergythat is released or absorbed during these processes. Every substance, whether naturally occurring or artificially produced, consist...
However, the change might involve changes in energy. For example, ice melting is a physical change in that an increase in thermal energy changes the state of matter of water. However, the water molecules themselves are still water, i.e., two hydrogen atoms are still bonded to one oxygen ...

Energy and nutrients, or chemicals, flow through an ecosystem. While energy flows through the ecosystem and cannot be recycled, nutrients cycle within an ecosystem and are reused. Both energy flow and chemical cycling help define the structure and dynami
