Question

What is meant by a chemical reaction? Explain with the help of an example.

Answer 1

Hint: We must remember that the reaction means some matter reacts to form new matters. The world is dependent on some reactions that occur spontaneously. Chemical reactions play a vital role in the world. Without chemical reaction, nothing in the world. Photosynthesis is also one of the chemical reactions that occur in nature. In the world, two main reactions are classified, one is biological reactions in living organisms, and other is chemical reaction.

Complete step by step answer:
We must remember that chemical reactions are one of the important reactions in the world. In one process, one new substance with new properties is formed from a reactant with the help of another compound or it is called chemical reactions.
A good example of a chemical reaction is the rusting of iron.
We kept an iron rod or iron nail on the outside; it easily rusts and changes the color of the material. This color change is due to some chemical reactions that occur in iron material. This rusting of iron is due to moisture in the atmosphere, this moisture oxidized iron and to form iron oxide in the layer.
$2Fe + {O_2} \to 2FeO$
Here, iron is the reactant of this reaction, and iron oxide is the product of the reaction. This kind of oxide formation of metal in the chemical reaction is known as an oxidation reaction.

Note: We must remember that in a chemical reaction, reactants are always on the left side and products are always on the right side by arrow symbol to find the direction of the reaction. If more than one reactant or product in the reaction means using the plus symbol in between them. As we know that in a chemical reaction, so many parameters are important for product formation. Temperature, pressure, and concentration play an important role in proceeding with the reaction. There are many types of chemical reactions. There are oxidation reactions, reduction reaction, redox reaction, combustion reaction, displacement reaction, decomposition reaction, and combination reaction.
