Introduction :
Chemical reaction is defined as the changing one set chemical reactions into other set of chemical reactions. There is no need to give input to the chemical reactions. Chemical reactions involves the transfer of electrons and the formation of chemical bonds. Reactants are the substance which are involved in the chemical reactions. Nuclear reactions are also takes place in the chemical reactions. There are three types of chemical reactions are present.
Oxidation reaction and reduction reaction:
Oxidation and reduction reaction are defined as one substance gets oxidised and the other substance gets reduced. Simply it is defined as the loss or gain of electrons. Some of the examples involves in this type of chemical reaction are,
1. Iron and oxygen reaction:
In this example, the ion reacts with the oxygen and it produces oxide. In this the oxidised substance is iron. The chemical reaction is as follows,
4Fe + 3O2 `->` 2Fe2O3
Where
Fe = iron
O2 = oxygen
2Fe2O3 = oxide
2. Ethanol and oxygen reaction:
In this example, the ethanol reacts with the oxygen, thus producing an acid called ethanol. In this the oxidised substance is ethanol.
CH3 CH2 OH + [ O ] `->` CH3COOH
Where,
The formation of salt and water by using the reaction of acid and the metal oxide is called as the acid – metal reaction. The example of chemical reaction is, The acid hydrochloric acid reacts with the metal oxide iron oxide,thus producing iron chloride and solvent water
3HCl + Fe2O3 `->` FeCl3 + 3H2O
Three types of chemical reaction
Acid – Base Reactions:
The formation of salt and water by using the reaction of acid and base are called as the Acid-Base reactions. The examples for this chemical reaction are ,
The acid hydrochloric acid reacts with the base sodium hydroxide, thus producing a salt called sodium chloride and solvent water
HCl + NaOH NaCl + H2O
Where,
HCl = hydrochloric acid
NaOH = sodium hydroxide
NaCl = sodium chloride
H2O = water
Another example,
The acid sulphuric acid reacts with the base potassium hydroxide, thus producing a potassium sulphate and the solvent water
H2SO4 + 2KOH K2SO4 + 2H2O
Where,
H2SO4 = sulphuric acid
KOH = potassium hydroxide
K2SO4 = potassium sulphate
H2O = water

Different Types of Chemical Reactions:
There are three types of chemical reactions are present. The three types are defined in the following,Oxidation reaction and reduction reaction:
Oxidation and reduction reaction are defined as one substance gets oxidised and the other substance gets reduced. Simply it is defined as the loss or gain of electrons. Some of the examples involves in this type of chemical reaction are,

In this example, the ethanol reacts with the oxygen, thus producing an acid called ethanol. In this the oxidised substance is ethanol.
CH3 CH2 OH + [ O ] `->` CH3COOH
Where,
CH3 CH2 OH = ethanol
[ O ] = other chemicals
CH3COOH = ethanoic acid
Acid – Metal oxide Reaction:The formation of salt and water by using the reaction of acid and the metal oxide is called as the acid – metal reaction. The example of chemical reaction is, The acid hydrochloric acid reacts with the metal oxide iron oxide,thus producing iron chloride and solvent water
3HCl + Fe2O3 `->` FeCl3 + 3H2O
HCl = hydrochloric acid
Fe2O3 = iron oxide
FeCl3 = iron chloride
