Definition and scope of chemistry
Chemistry is a branch of physical sciences. Chemistry deals with composition, structure, properties and change of matter. Chemistry deals with constituents of a matter like, atoms and molecules; their interactions, transformations and the formation of new chemical substances.
It can be divided into the following branches:
1. Inorganic chemistry
The study of inorganic substances and compounds.
2. Organic chemistry
The study of structure, property and reactions or organic compounds.
The study of chemical reactions taking place within human beings and other living organisms.
The study of neuro-chemicals of the living body.
5. Nuclear chemistry
The study of sub-atomic particles.
6. Quantum chemistry
The study of physical basis of the chemical systems using quantum physics.
History of the discipline
The word chemistry comes from the word alchemy. It was an ancient set of practices, which encompassed elements of magic and science. An alchemist was one who practiced this art of alchemy. Later on an alchemist was called a chemist in popular speech from which the word chemistry was derived by adding a “ry” in the end.
Chemistry as a science was developed as a science only under the influence of scientists such as Sir Francis Bacon, Robert Boyle and John Mayow. Organic chemistry was developed by Justus Von Liebig and Friedrich Wohler.

Basic processes of chemistry
Some of the most important chemical processes are the following:
1. Chemical Bond
Atoms sticking together in molecules and crystals are said to be in a chemical bond. New chemical substances are formed when chemical bonding takes place between two different atoms.
It is the attribute of a substance because of its atomic, molecular or total structure. During a chemical reaction, the chemical structure changes, as such it is accompanied an increase or decrease of energy.
3. Chemical Reaction
When a chemical substance is transformed because of its interaction with another substance, a chemical reaction is said to have taken place.
4. Acid-Base Reaction
A substance can be classified either as an acid or a base. An acid is a chemical substance which is characterized by its sour taste, its ability to transform blue litmus red and its ability to react with base. A base on the other hand is a substance that in an aqueous solution is slippery to touch, tu
s red litmus paper blue and reacts with acid to form salts. A chemical reaction between an acid and a base is called acid-base reaction.
5. Chemical equilibrium
Chemical equilibrium is that stage in a chemical reaction when both the reactants and the products are present in concentrated forms and have no further ability to change with time.
Basic chemical laws which students will need
Chemistry assignment help can be made easy if you keep these chemical laws handy.
1. Avogadro’s laws
“Equal volumes of all gases, at the same temperature and pressure will have the same number of molecules”.
2. Boyle’s law
“The absolute pressure exerted by a given mass of an ideal gas is inversely proportional to the volume it occupies if the temperature and amount of gas remains unchanged within a closed system”.
3. Charles law
“When the pressure of simple dry gas is held constant, the Kelvin temperature and the volume will be directly related”.
4. Henry’s law:
“The solubility of a gas in a liquid is directly proportional to the partial pressure of the gas in equilibrium with that liquid”

Application of chemistry in real life
Chemistry has surpassed the narrow boundaries of mode
universities has entered the industrial world. The chemical industry is one of the largest and most flourishing sectors of any economy. Chemical industry produces large scale industrial chemicals. Chemical companies transform raw materials like petroleum, natural gas, minerals and metals into different industrial products for sale. Some of the important products we use in everyday life are:
- Industrial gums and adhesives
- Consumer products like soaps, detergents and cosmetics
