The Scopes of Chemistry

The Scopes of Chemistry

Wherever there is an element, there is chemistry. Various gaseous elements are there in the air. There are continuous chemical changes occurring in the air. The same is there in the soil we are living on.

It happening now, it happened in the ancient days too. The earth was highly heated at the moment of its creation. There was no wind, nor any animal. It took millions of years of chemical reactions for the creation of the atmosphere, water, and thousands of other elements.

These altogether contributed to the habitability of the earth for animals. All animals including human beings have microscopic lives like bacteria, amoeba, huge trees and animals have bodies that contain various kinds of chemicals.

Each body is a kind of chemical factory where chemical reactions are taking place every moment. We live because of these chemical reactions. Again, with the advent of civilization, humans have produced various necessary items and products by means of chemical reactions and put them to their use.

For example, the dresses you put on, the paste you brush your teeth with, the comb you fix your hair with, the cosmetics you use on your skin-all are chemical products. Besides, soap, toilet cleaner, life-saving drugs, all are chemicals too.

We use fertilizers and insecticides in our field crops, use petrol, diesel, etc. in vehicles. These are industrial products made out of chemical reactions. In fact, the scope of Chemistry is so vast that it cannot be summarized easily. The table below tries to present some of the scopes in brief:

Some scopes of chemistry:

Substance   Element  Source and Chemical Change
 Air Mostly oxygenWhen we inhale air, the oxygen in it reacts with the food substances inside our body and produces energy.
 Drinking water Hydrogen, oxygen, and mineral salts Water plays a role in the chemical reactions that take place inside our bodies. It also works as a solvent of various substances in the body. The poisonous substances in the body mix with water and come out in the form of urine and sweat. Mineral salts such as calcium, magnesium, etc. play a vital role in our body.
 Fertilizer Nitrogen, oxygen, carbon, phosphorous, calcium, magnesium, potassium, etc.The elements are highly necessary for plants. Different fertilizers contain compounds of these substances. As a result, these fertilizers act as nutrients and help get a good crop.
 Paper CellulosePaper is one of the most significant inventions of human civilization. Bamboo, the outer skin of sugarcane, etc. contains huge amounts of cellulose. The paper mills turn these sources into papers by means of chemical reactions.
