Question

Chemical reaction and their types chemical combination decomposition displacement double displacement radox reaction and definitions and examples

Answer 1

CHEMICAL REACTION-

Chemical reaction are the process in which new substance with new properties are formed...Eg:- Mg+O2 = Mgo

COMBINATION REACTION- When 2 or more substance combine to form a single new substance.. Then,it is called Combination reaction...Eg:- H2+O2= H2O

DECOMPOSITION REACTION- Those reactions in which compound splits up into two or more simpler substances are known as Decomposition reaction..Eg:- CaCO3= CaO+CO2

DISPLACEMENT REACTION- Those reaction in which one element takes the place of another element in a compound, are known as Displacement reaction..Eg:- CuSO4 + Zn= ZnSO4+Cu

DOUBLE DISPLACEMENT REACTION- Those substance in which two compound reacts by an exchange of ions to form two new compound are called Double Displacement reaction...Eg:- AgNO3 +NACl = AgCl + NaNO3

REDOX REACTION- The substance which gives oxygen for oxidation is called an oxidising reaction and The substance which gives hydrogen for reduction is called reduction reaction...

The oxidation and reduction reaction are also called redox reaction...Eg:- Cuo + H2 = Cu + H2O..
