Question

What are chemical reactions and define it's types

Answer 1

Chemical Reaction:-

Chemical reaction is the process of conversion of one substance to the other. It is the change that involves only electrons of the atoms or elements which is involved in the chemical reaction.

Chemical reaction can be classified into seven types  :-

1. Combination reaction

2. Decomposition reaction  

3. Single Displacement Reactions  

4. Double Displacement Reactions.

(i) Precipitation (ii) Acid-Base Neutralization.

5. Combustion.  

6. Organic reactions

7. Redox reaction

Answer 2

Here is your answer ⤵⤵⤵⤵⤵⤵

Whenever a chemical change occur, chemical reaction takes place.


Types of chemical reactions are :-

1) Combination reaction- The type of reaction in which two or more compounds combine together to give a single substance.

2) Decomposition reaction- The type of reaction in which a single substance is broken into two or more simpler substance.

3) Displacement reaction- When an atom or a group of atoms present in a molecule is displaced by another group of atom.

4) Double Displacement reaction - The type of reaction in which two compounds exchange their ions to give two new compounds.

5) Redox- The reaction in which oxidation and reduction takes place simultaneously.

>> Oxidation - When oxygen is added and hydrogen and electrons are removed.

>> Reduction - When hydrogen and electrons are added and oxygen is removed.
