What does energy have to do with chemistry?
Chemical energy is the energy stored in the bonds of chemical compounds. Chemical energy may be released during a chemical reaction, often in the form of heat; such reactions are called exothermic reactions. Reactions that require the input of heat to proceed may store some of this energy as chemical energy in newly formed bonds.
The chemical energy stored in molecules and atoms is released when new chemical bonds are formed. It can also be said that the new bonds formed in a chemical reaction that releases energy to the surroundings are more stable than the chemical bonds that were present in the reacting particles.
In chemical reactions, energy is released if the process is exothermic, and absorbed if it is absorptive. The starting materials of an absorptive reaction, plus a certain amount of heat (energy), give the products. It can be shown that the energy of the products is equal to the sum of the energy that the starting materials contained plus the heat added.
Energy stored in the bonds of chemical compounds (molecules and atoms). It is released in a chemical reaction and mostly produces heat as a byproduct, known as an exothermic reaction. Examples of stored chemical energy include biomass, batteries, natural gas, petroleum, and coal. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy. For example, chemical energy is converted to heat energy when people burn wood in a fireplace or burn gasoline in a car engine.
Chemical energy can only be observed and measured when a chemical reaction occurs. Any substance that is considered a fuel contains chemical energy. The energy can be released or absorbed.
Chemical energy is converted to electricity
An example of this is a battery: A device that stores chemical energy and converts it to electrical energy. Chemical reactions in a battery involve the flow of electrons from one substance (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.
What are the disadvantages of chemical energy?
First of all, chemical energy is not a clean form of energy. Most forms of chemical energy can only be obtained through combustion, other forms of consumption, or the production of byproducts. Emissions are often a by-product of these processes, which can have a negative impact on the planet.
Chemical energy is available in nature, the most important of which are existing fuels such as oil, coal, natural gas, and wood. Chemical energy binds the atoms of a single molecule together in chemical compounds or components of the nucleus in elements that participate in nuclear fission and fusion reactions.
Use of chemical energy in industries
From a technical point of view, fuel is considered stored chemical energy, and when we burn it, such as in an internal combustion engine or a jet plane, it is converted into mechanical energy. A fuel cell can also convert the energy of a chemical reaction into direct electrical energy.
When a battery is used, the chemical energy is converted through an oxidation-reduction reaction into direct electrical energy. The accumulator also works in a similar way to a battery, but it differs from the battery in that it can be recharged, and during that process the electrical energy in it is converted into chemical energy stored until it is used.
What is the chemical energy in food?
Food contains chemical energy. Chemical energy is the energy stored in bonds. Food contains proteins, fats, and carbohydrates; All of these contain a lot of ionic and covalent bonds. All the energy in these bonds is known as chemical energy, and can be released in the form of ATP in human cells.
The metabolism process in living organisms produces heat and work, for example 37 degrees Celsius. When we work or carry a load or run, the burning of food in the body increases, so we sweat, because without sweat, our body temperature would rise to dangerous temperatures. Sweat cools the body from excess heat. Green plants convert the sun's energy into chemical energy through photosynthesis, and can form sugar, which is fuel for our bodies. We can make alcohol from sugar and light a stove or run a car with it.
