Question

What are the four forms of energy that may be absorbed or released during a chemical reaction?

Answer 1

There are many types of reactions in which many types of energies are absorbed or released, so these reactions are exothermic reaction, endothermic reaction, electrolysis reaction, and photochemical reaction.

Complete answer:
We know that chemical reactions are the process in which chemical compounds are converted into different chemical compounds. The compounds that are converted are known as reactants and the compounds formed are products. For this chemical reaction to occur there are many types of energy either required or released in the reaction.
The four types of energy that are related to the absorption or released during the chemical reactions are heat energy, light energy, sound energy, and electrical energy.
Based on the energies mentioned above there are many types of reaction in which these energies are absorbed or released, so these reactions are exothermic reaction, endothermic reaction, electrolysis reaction, and photochemical reaction.
In exothermic reactions, the heat energy is released while in the endothermic reaction the heat energy is absorbed.
In electrolysis reactions, electric energy is released which is used for supplying electricity for home and industrial uses.
In a photochemical reaction, light energy is required to initiate the reaction.
When the bonds break in a reaction, the sound energy is produced, and sometimes when new bonds are formed even then sound is released.

Note:
An example of an exothermic and endothermic reaction is the reaction of water with sulfuric acid and reaction of ammonium chloride with water respectively. An example of electrolysis reactions takes place in nickel-cadmium cells and a reaction between hydrogen and chlorine gas is an example of photochemical reaction.
