The Chemical Reactions

What are Chemical Reactions?

Chemical reactions are concerned with breaking of old bonds to create

new bonds. It is the interaction of two or more substances, resulting in chemical

changes in them. 

Chemical reactions take place when some kind of energy is supplied to them. The supplied energy may be in the form of heat, light or mechanical shaking for proper contact between the reactant molecules or

electricity. 

 Chemical reactions involve rearrangement of the atoms and produce

new substances in this process.

For example, just the mixing of two substances can cause

the chemical reaction to occur.

Chemical Reactions are everywhere in nature.

The process by which the plants make their own food is called photosynthesis. 

In the presence of sunlight , the chemical reactions take place on the surface of

the leaf. The green pigment inside the leaves called “chlorophyll” help in the

manufacturing of food by making use of CO2 , H2O and other soil nutrients. In 

this process Oxygen is released, which is our daily consumption.Our Body is a Big Chemical Factory

Chemical Reactions take place in our body too. 

Our whole body depends on

chemical reactions for proper functioning. These chemical reactions keep on

happening in our body throughout our life. 

For example, the whole digestion process involves chemical reaction of acids

and the food. During digestion, the food is broken down in to smaller

molecules. The salivary glands in our mouth release digestive enzymes which 

help in the breakdown of food. Digestion continues in the stomach and small

intestine with the help of digestive enzymes.

Oxidation Reaction – Oxidation reaction is a reaction with oxygen. 

 Oxidation is used in a wide variety of industries such as in the production of cleaning

products. It involves the loss of an electron by a molecule, atom, or ion.

Reduction Reaction – Reduction is the opposite of oxidation, it is often 

reaction with hydrogen. It involves gain of an electron by a molecule, atom, or

ion. 

The oxidation and reduction always go together because one cannot occur

without the other. Electrons that are lost by one atom must be gained by 

another.
