                    Chemical reaction and equation Chemical reaction  :- the process in which orignal substance looses its nature and identity and new chemical substance will be formed with new chemical properties is called chemical reaction.                         example :-    cooking of food                                             digestion of food                                               respiration                                             burning of fuels Characteristics of chemical reaction:- 1.Change in colour 2.  Change in state                                                                                                                                     3.  Change in temperature                                                                                                                                                            4.  Evolution of gas
