Hey friends here is your answer------_______________^^^^^^^^^^***********
In decomposition reactions, a single compound breaks down into two or more simpler substances (elements and/or compounds). The decomposition of water into hydrogen and oxygen gases, and the decomposition of hydrogen peroxide to form oxygen gas and water, are examples of decomposition reactions......
There are five types of chemical reactions: Combination/Synthesis Reactions: two or more substances combine to form a new compound (A+X->AX). Includes, but is not limited to, the reactions of elements with Oxygen and Sulfur; the reactions of metals with Halogens; and Synthesis reactions with Oxides........
Hope it will help you.........----------------------------------------

Hey there!!
=>> several types of reactions can occur depending on what happens when going from reactants to products. the most common ones are:-
1. Combination reaction
2. decomposition reaction
3.displacement reaction.
4.double displacement reaction.
5. redox reaction.
@ Combination reaction:- A reaction in which two or more substances combine to produce a single substance is known as combination.
=>> 2CaO + 2H2O → 2Ca(OH)2
@ Decomposition reaction : A reaction in which a complex reactant is converted into two or more simple molecule, then the reaction is called as decomposition reaction.
=>> CaCO3 -> CaO + CO2
@ Displacement reaction:-- reaction is the one in which one more reactive element displaces the less reactive from a compound.
=>> for example :- Fe+CuSO4−FeSO4+Cu.
@ A Double Displacement Reaction is a bimolecular process in which parts of two compounds are exchanged to give two new compounds.
=>> Example:- Pb (N03)2 + 2k – Pbl2 + 2kNO3.
Thus, double Displacement Reactions have two common features:
Firstly, two compounds exchange their ions resulting in the formation of new compounds.
Secondly, one of the new products formed would be separated from the mixture in some way (commonly as a solid or gas).
@ Redox reactions are reactions in which atoms undergo a change in their oxidation state. These are a combination of oxidation and reduction reaction which occur simultaneously.
Oxidation can be described as the loss of electrons and
Reduction is defined as the gain of electrons.
In a redox reaction, one of the elements undergoes reduction while another species undergo oxidation.
An example of redox reaction:
MnO4 - (aq) + Fe2+ (aq) → Mn2+ (aq) + Fe3+ (aq)
In the above reaction,
Iron is oxidized as it loses an electron to form Fe3+ ion
And Manganese is reduced From +7 oxidation state to +2 by gaining 5 electrons.
Hope it helped!!!!☺️
