In composition reaction one product is formed from the combination of two or more substance this is also why it is called as composition reaction.
in this simple compound result in formation of complex compound .
This reaction result in bonding of atoms which result in a single product.
In decomposition more then one product is formed from the breakage of one reactant.
In this reaction bonds are broken between the compound result in production of more product from that one.
In this reaction complex compound ultimately result in simple compound.

Answer:
Explanation:
Hey friend !
Combination reaction:-
It is a chemical reaction in which two or more reactants combine with each other to form a new single product.
It releases heat during the chemical reaction.
This means that it is exothermic .
Examples :-
1) 2H₂ + O₂ ---->2H₂O
2) 2Mg + O₂ --->2MgO
Decomposition reaction:-
It is a chemical reaction in which one reactant breaks down into simpler compounds.
It absorbs heat from the surroundings during the chemical reaction.
IN other words , it is endothermic .
Examples :-
CaCO₃ ===> CaO + CO₂
2H₂O ===> 2H₂ + O₂
