Chemotrops are further divided into two groups on the basis of source of electron Chemolithotrops they gain energy from oxidation of chemical compound and reduces inorganic compounds such as NH3 as electron source Eg NitrosomonasThe specific chemical exergy of water is (3110) b chw = g w(p 0, T 0) − μ w, 0 where g w(T 0, p 0) is the specific Gibbs potential of water at ambient pressure and temperature and μ w, 0 is the chemical potential of water in the RE If the chosen RE were the saturated air, then μ w, 0 = μ v(p s(T 0)), where p s is the saturationChemical energy is stored as food for us to use This energy came from the Sun Energy in our food is stored in chemical bonds Plants transform the sun's radiant energy into a "glue" for chemicals like sugar (sucrose) The plants store the sugars

A fuel cell is a device that converts the chemical energy from fuel into electricity via a chemical reaction with oxygen or another oxidizing agent Hydrogen is the most common fuel, but hydrocarbons such as natural gas and alcohols are sometimes used Fuel cells are different from batteries in that they require a constant source of fuel andWhen a chemical bond is broken, it is usually accompanied by a release of energy Similarly, the formation of chemical bonds requires an input of energy The energy supplied/released can be of various forms (such as heat, light, and electricity)> Nuclear Energy Nuclear energy is stored in the nucleus of atoms This energy is released when the nuclei are combined (fusion) or split
Chemical potential energy is the energy stored in the chemical bonds of a substance The various chemicals that make up gasoline contain a large amount of chemical potential energy that is released when the gasoline is burned in a controlled way in the engine of the car The release of that energy does two thingsThe chemical exergy is an ideal mixture of ideal gas N as follows 1,3,4 (57) e ¯ M, i g C H = ∑ k = 1 N x k e ¯ k C H R ¯ T 0 ∑ k = 1 N x k L n x k If the temperature of the environment is T0, e ¯ k C H is the chemical standard molar mass of the k th chemical material, and xk is the mole fraction of k in the system at T0 1EG Chemistry Co, Ltd Company Description EG Chemistry leads new millenium in the fields of Excision Chemical Industry and Environmental Industry in the WorldWe provide complete corrosion protection in variety of forms to suit your steel products

The chemical energy in form of ATP is then used in biosynthesis to fix carbon in order to produce organic compounds * This process is different from photosynthesis where autotrophs are able to produce their own energy by using energy from the sun (sunlight) Because chemolithotrophs do not have access to sunlight, they have to rely onThe energy from macronutrients comes from their chemical bonds This chemical energy is converted into cellular energy that can be utilized to perform work, allowing cells to conduct their basic functions Although vitamins also have energy in their chemical bonds, our bodies do not make the enzymes to break these bonds and release this energySuch reactions are called exothermic Reactions that require an input of heat to proceed may store some of that energy as chemical energy in newly formed bonds The chemical energy in food is converted by the body into
