Chemical Energy Examples –

when we think of examples of chemical energy Test tubes, laboratory images, and chemical mixtures come to mind. Although chemical energy is all about science, its impact on our daily lives is vast, even if we have never visited a laboratory. The chemical energy it’s in the food we eat, the electricity we generate, and even in plants.

What is chemical energy?

Chemical energy is a reserve of energy, one of the most crucial energy reserves available to us. The energy stored in an object is a form of potential energy.
The potential energy of chemical energy is stored in the chemical bonds that join atoms in molecules. Breaking these bonds or reforming them by adding fuels or reagents releases the chemical energy of the bonds. We call this breaking and forming of bonds a chemical reaction. A new substance is created after a chemical reaction.
Fuels or reactants provide the energy needed to transform chemical potential energy into chemical energy. Our ability to carry chemical potential energy and harness chemical energy is why it has become critical to our energy systems.

What is potential chemical energy?

we know the potential chemical energy stored in an object due to the number and type of chemical bonds it contains. Understanding these values ​​helps us choose how to use chemical energy.
Motor vehicles are an excellent example to consider. A pickup truck with an empty fuel tank parked at the top of a hill has the potential energy to move down the hill. That same truck at the bottom of a hill has less potential energy because it will not move uphill easily.
However, if we fill your tank with gasoline, we are filling it with fuel made up of various chemical compounds. The van’s combustion engine burns the gas, creating new substances by breaking and reforming the bonds within the gasoline’s molecules and atoms. A certain amount of energy is used to move the van and some of it generates heat.
Many fuels, such as biofuels, propane, methane, and more, have potential chemical energy. We generate electricity in power plants by burning fossil fuels such as natural gas, coal, and oil, releasing the potential chemical energy of these materials. These reactions are called exothermic reactions.

What happens during an exothermic reaction?

A chemical reaction that produces heat is exothermic, heating up its surroundings thanks to the energy released during the process.
Exothermic reactions are an everyday part of our lives. We have already seen how combustion reactions, or burning, occur when we burn fuels. This chemical reaction releases thermal energy in the form of heat energy: imagine the flames of a fire or a natural gas power plant. Another exothermic reaction is crucial in the battle against climate change. Burning coal in a power plant creates a chemical reaction between carbon stored in the coal and ambient oxygen, which combine to release carbon dioxide and heat. These exothermic reactions take place when a substance reacts with oxygen. We call them oxidation reactions and they also produce oxides.
A painful reminder of another exothermic reaction occurring when a bee stings us. A bee sting is acidic, and an old remedy is to treat it with baking soda. What happens at the molecular level is called a neutralization reaction. This reaction occurs when an acid such as a bee sting interacts with substances called bases such as baking soda. We call this a neutralization reaction when the chemical reaction produces water and salt. With exothermic reactions, more energy is released as new bonds are formed than the energy required to break the bonds in the reactants.

Examples of chemical energy in everyday life

Numerous examples of chemical energy are given in our daily lives. Here are a few you’ll probably recognize:

Food: Our bodies create chemical reactions to break down the chemical compounds in food to release energy.Propane: Heat and light are the result of burning propane, which is used to heat spaces, buses, cooking, and batteries– Chemicals store energy in battery cells which is then converted into electrical energy to help run cars.explosives: These store chemical energy. The explosions produce light and heat in a gaseous form, providing an example of how unstable compounds rearrange their bonds easily and quickly.Petroleum: Combustion engines cause heat and energy to be released by rearranging atoms and molecules.Floors. Plants store energy from the sun as chemical energy in sugar (glucose) and produce oxygen through photosynthesis. Glucose is present in leaf cells (called chloroplasts) which are filled with chlorophyll to facilitate light absorption.Chimney. Dry wood contains stored chemical energy. When you burn that wood in a fireplace, chemical energy is released and converted into thermal energy (heat) and light energy. And what about the wood? After the chemical reaction, it turns into a new substance: ash.Ignite a phosphorous. Contact of the phosphor with the cardboard surface ignites the phosphor by a chemical energy reaction.

How do we generate energy with chemical energy?

The chemical energy it is one of the pillars of our energy supply, producing heat, electricity and powering transportation around the world.
The burning of fossil fuels produces steam to turn turbines that produce electricity. We also burn biomass, biodiesel, biofuels and more products for the same purpose.
Our planes, lawn mowers, cars, and more machines run on fuels we burn. Batteries store chemical energy for later use.
With climate change upon us, solar panel technology has rapidly improved our ability to convert the sun’s rays into chemical energy that we transform into electrical energy.

Is wood a source of chemical energy?

wood in any form has chemical energy. It has potential chemical energy while waiting for combustion, and chemical energy is released during combustion, emitted in the form of light and heat.
Burning wood in a traditional cooking stove is an exothermic reaction that releases the potential energy of the wood as heat, heating up the stove and kitchen.
Trees grow thanks to the energy of the sun. Wood is considered by some to be a renewable energy source because it can regrow during our lifetime. Wood is classified as a biomass fuel because it is energy from a plant or animal.
