Role of CHEMISTRY

 Hello Viewers!

Previously we have discussed about meaning of chemistry.Today we will discuss some roles of chemistry in daily life.

The knowledge that provides understanding of this world and how it works, is science.

Development of science and technology has provided us a lot of facilities in daily life. Have you ever wondered about the importance of chemistry in daily life? You might ask this question if you are student of chemistry. Finding it's answer is one of interesting homework. Here's a look why chemistry is important. 

Imagine the role and important of important petrochemical products,  medicines and drugs,  soap,  detergents,  paper,  plastics, paints and  pigments,  insecticides,  pesticides which all are fruit of the efforts of chemists. The development of chemical industry has also generated toxic wastes, contaminated water and polluted air around us. On the other hand chemistry also provides knowledge and techniques to improve our health and environment and to explore and to conserve the natural resources.

Now take general examples:

Everything is made of chemical. You are made of chemical. Your pet, your chair, your desk, everything is made of chemical. So, our Sun is chemical. Medicines/drugs are chemicals. Similarly food is also made from chemicals. 

Many of the changes observed in the world  are caused by chemical reactions. Examples include leaves changing colors, cooking food and getting yourself clean.

Chemistry is fun! It can be used to make colors change, alter recipes, color flames, make things glow in the dark, or even make stuff explode. Many people study chemistry not because it's a requirement for a class but because they are interested in using it to explore the world and to try science projects. As hobbies go, chemistry is inexpensive because home chemicals can be used to perform many interesting experiments.


I hope my this information will be useful as well as helpful for you all. If you think it interesting you can learn it easily.

Nitrogen Cycle

 Nitrogen occurs prominently in all the spheres of the environment. The atmosphere is 78% elemental nitrogen, N2, by volume and comprises an inexhaustible reservoir of this essential element. Nitrogen, although constituting much less of biomass than carbon or oxygenoxygen, is an essential constituent of proteins. The N2 molecule is very stable so that breaking it down into atoms that can be incorporated with inorganic and organic chemical forms of nitrogen is the limit- ing step in the nitrogen cycle. This does occur by highly energetic processes in lightning discharges that produce nitrogen oxides. Elemental nitrogen is also incorporated into chemically bound forms. or fixed by biochemical processes mediated by microorganisms. The biological nitrogen is mineral- ized to the inorganic form during the decay of biomass. Large quantities of nitrogen are fixed synthetically under high-temperature and high-pressure conditions according to the following over- all reaction:     ...

Cycles of Matter

 Very much connected with environmental chemistry, cycles of matter, often based on elemental cycles, are of utmost importance in the environment. Global geochemical cycles can be regarded from the viewpoint of various reservoirs, such as oceans, sediments, and the atmosphere, connected by conduits through which matter moves continuously among the hydrosphere, atmosphere, geo- sphere, biosphere, and, increasingly, the anthrosphere. The movement of a specific kind of matter between two particular reservoirs may be reversible or irreversible. The fluxes of movement for particular kinds of matter vary greatly as do the contents of such matter in a specified reservoir. Most cycles of matter have a strong biotic component, especially through the biochemical processesof plants and microorganisms. The cycles in which organisms participate are called biogeochemical cycles, which describe the circulation of matter, particularly plant and animal nutrients, through ecosystems. Most biogeoche...

Structure of Atom (Part 6)

Bohr's Atomic Theory: Keeping in view the defects in Rutherford's Atomic Model, Neil Bohr presented another model of atom in 1913.The Quantum Theory of Max Planck was used as foundation for this model. According to Bohr's model, revolving electron in an atom does not absorb or emit energy continuously. The energy of a revolving electron is 'quantized' as it revolves only in orbits of fixed energy, called 'energy levels' by him.  The Bohr's atomic model was based upon the following postulates: i. The hydrogen atom consists of a tiny nucleus and electrons are revolving in one of circular orbits of radius ‘r’ around the nucleus. ii. Each orbit has a fixed energy that is quantized.  iii. As long as electron remains in a particular orbit, it does not radiate or absorb energy. The energy is emitted or absorbed only when an electron jumps from one orbit to another. iv. When an electron jumps from lower orbit to higher orbit, it absorbs energy and when it jumps ...
