What is Chemical Reaction: Chemical reactions are the processes in which a new substance with the new properties is formed.Chemical reactions involve chemical changes.

It is not that chemical reaction can be carried only in the science laboratory.A large number of chemical reactions keep occurring in our daily life.Soaring of milk, a formation of curd, cooking of food, digestion of food, a process of respiration, fermentation of grapes, rusting of iron, burning of a candle, ripening of fruits all is chemical change. In all this case is the identity and nature of substance changes because the chemical reaction takes place in it.

Now it is clear to you What is Chemical Reaction.

What is Chemical Reaction (New Concept)

1. Reactant: The substance which takes part in the chemical reaction.

2.Product: The new substances produced as a result of chemical reactions.

In a chemical reaction, the substances to react, we call substances as a reactant and convert into new substance called product.During the chemical reaction rearrangement of atoms takes place.As a result, a new substance from after the reaction has entirely different properties.A chemical reaction involves breaking of old Bond and making of the new chemical bond of a new substance.During a chemical reaction atoms of one element do not change into another element.The only rearrangement of atoms takes place in a chemical reaction.

Characteristics of Chemical Reaction

In a chemical reaction, reactant reacts to change into the product.

Important characteristics of chemical reactions.

1. Evolution of gas.

2.Formation of precipitation.

3.Change in colour.

4.Change in temperature and

5.Change in the state.

Any one of these general characteristics tells us whether a chemical reaction has taken place or not. For example: On mixing two substance, if a gas evolves.Then we can say a chemical reaction has taken place.Similarly for others characteristics.
