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
