Chemicals like Laughing gas, Hydrochloric acid, Nitric acid and several others are going to be explained in the most easiest and practical ways. Practical situations like existence of fire and the chemical processes involved in this would be discussed. Moreover human body chemicals and nutrients are also being discussed in the most interesting way !
