Deffrenciate chemical combination reaction and chemical decomposition

1.	Deffrenciate chemical combination reaction and chemical decomposition 2points
Answer» Explanation: 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
