Answer 2

Different chemical reactions are..
1: Combination reaction or addition reaction -: A reaction in which two or more than two substances are combined together to form a single compound or product, is called a combination reaction.
2:Decomposition reaction-:The reaction in which one compound splits up into two or more simpler substances, are called decomposition reactions.
It's of three types
a: Thermal decomposition reaction
b:Electrolytic decomposition reaction
c:Photochemical decomposition reaction.
3:Displacement reaction -: When an atom or a group of atoms is replaced by another atom or a group of atoms in a chemical reaction called displacement reaction.
4: Double Displacement reaction : These are the reactions in which ions of two ionic compounds are exchanged to produce new compounds..
5: Oxidation -Reduction Reactions-:Oxidation is defined as the reaction in which either oxygen is added to a substance or hydrogen is removed from substance.
Reduction.... It is defined as a reaction in which either hydrogen is added to a substance or oxygen is removed from a substance.
Oxidation and Reduction also known as "REDOX REACTIONS"
