The place of chemicals in everyday life

The place of chemicals in everyday life is very important and significant. All creatures in the universe are composed or decomposed of chemicals, whether in space or on Earth, and especially in the human body.
In life, everything we eat, drink and wear, or all the tools and equipment we use, are all the result of a combination of different chemicals, which we will describe in more detail below.
The human body is like a very large petrochemical that we see in its full function in our daily activities, such as happiness, sadness, love and hate, joy and anger, etc. Therefore, chemical in the form of pharmaceutical items can intensify or alleviate these emotional reaction. 

Carbon and oxygen are the two main elements of the body. Other elements in the human body are: nitrogen, phosphorus, hydrogen, calcium, sulfur, magnesium and etc. Deficiency of any of these elements can cause various side effects for the body, but with help of supplements, this deficiency is partially compensated.
In plants, the chemical reaction that occurs through photosynthesis is the most common and vital reaction that causes their growth and survival, which is also present in various fruits and vegetables.
Animals, like other living things on these planets are subject to the same chemical operations and feedback in appearance.
In all cosmetic items and detergents, there is a process of combining chemicals that have the ability to maintain the body or clean the body or the equipment around us.
Flour is also converted into dough in a chemical process and improved by another chemical additive, and in the face of fire, it experiences another chemical process and becomes edible bread.
In food preservatives, chemicals called sodium benzoate, potassium sorbate, sodium nitrite, sorbic acid, propionic acid, etc. are used to fight fungi and harmful molds. Other chemicals also work to digest food in the body.
Sunscreens also use chemicals to prevent UV rays from penetrating deep into the skin and protecting the skin. 
There is a discussion of corrosion and oxidation in metals, which is called rust in iron, so chemicals such as benzene triazole, etc. are used to protect the metal from rust and corrosion.
In today’s society, we use batteries in many devices, so our approach is to use lithium batteries that use cobalt sulfate to increase heat resistance.
The above is a small example of the effect of chemicals on our environment or on our body and being that we experience in our daily lives.
