CHEMICAL REACTIONS AND EQUATIONS Chemical Reaction :- “Chemical reactions are the process in which new substances with new properties are formed.” A chemical reaction represents the change of the species ( atoms or molecules ) taking part in the reaction into new species. A substances which take part in the chemical reaction are called reactants . A new substances produced as a result of chemical reaction is called products . Some examples of chemical reaction Souring of milk, Cooking of food, Rusting of Iron, Ripening of food, Burning of foods etc. Characteristic Feature Of Chemical Changes There is generally a change in colour of reacting species taking part in the change. The physical state of substance normally change. In some chemical reaction, gas may evolved. In some chemical reaction precipitate may formed. In most of chemical reaction temperature is changed. Before we go further , we should know the meaning of term ‘exothermic’ and ‘endoth
