== 'Chemical reactions'

Combination reaction : When two or more reactants combine in a reaction to form a single product, it is called combination reaction.

Decomposition reaction : The chemical reaction in which two or more products are formed from a single reactant is called decomposition reaction.

Displacement reaction : The reaction in which the place of the ion of a less reactive element in a compound is taken by another more reactive element by formation of its own ions, is called displacement reaction.

Double displacement reaction : The reaction in which ions in the reactants are exchanged to form a precipitate are called double displacement reaction.

Endothermic reaction : The reaction in which heat is absorbed is called endothermic reaction.

Exothermic reaction : The process in which heat is given out is called exothermic reaction.

Oxidation reaction : The chemical reaction in which a reactant combines with oxygen or loses hydrogen to form the product is called oxidation reaction.

Reduction reaction : The chemical reaction in which reactants gain hydrogen or loses oxygen to form product is called reduction reaction.
