Explain the difperent types of chemical reaction with
the help of examples.
Answers
Answer:
The different types chemical reaction are:
1. Combination reaction
2. Decomposition reaction
3. Displacement reaction
4. Neutralisation reaction
5. Double displacement reaction
6. Oxidation and reduction reaction
1. Combination reaction:
In a combination reaction, two or more elements combine to form a compound or an element and a compound can combine to form a new compound
For example:
Magnesium and oxygen combine when heated to from magnesium oxide,.
2. Displacement reaction:
Those reaction in which one element takes the place of another element in a compound, are known as displacement reaction. In general a more reactive element displacement reaction. In general a more reactive element displace element displace a less reactive element from its compound.
For example:
When a strip zinc metal is placed in copper sulphate solution, then zinc sulphate solution and copper are obtained
3. Double displacement reaction:
Those reaction in which two compounds by the exchange of ions to form two new compound are called double displacement reactions. A double displacement reaction usually occurs in solution and one of the products, being insoluble, precipitates out.
For example:
When silver nitrate solution is added to sodium chloride solution, then a white precipitate of silver chloride is formed long with sodium nitrate solution
In this double displacement reaction, two compounds, silver nitrate and sodium nitrate.
4. Oxidation and reduction reactions:
Oxidation:
1. The addition of oxygen to a substance is called oxidation.
2. The removal of hydrogen from a substance is also called oxidation.
Reduction:
1. The addition of hydrogen to a substance is called reaction.
2. The removal of oxygen from a substance is also called reduction.
From the above definitions it is clear that the process of reduction is just opposite oxidation. Moreover, oxidation and reduction reactions occurs together.
