1)The reaction in which the place of ion of a less reactive element in a compound is taken by another more reactive element by formation of its own ion,is called displacement reaction.
ex.Zn(s)+CuSO4(aq)------>ZnSO4(aq) +Cu(s)+Heat
2)The chemical reaction in which two or more products are formed from a single reactant is called decomposition reaction.
ex.C12H22O11(s)--∆------12C(s)+11H2O(g)
3)When two or more reactants combine in a reaction to form a single product,it is called a combination reaction.
ex.CaO(s)+H2O(l)------->Ca(OH)2(aq).
ex.Zn(s)+CuSO4(aq)------>ZnSO4(aq) +Cu(s)+Heat
