|
Answer» 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 --->2MgODecomposition 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 + CO₂2H₂O ===> 2H₂ + O₂ In combination reaction, 2 or more compounds combine together to form a new substance whereas in decomposition reaction, single compound splits up into 2 or more substance... |
