chemistry project on chemistry in everyday life

Introduction - Study of chemistry is important for the simple reason that, many chemicals find applications in almost all aspects of our daily life. The flow chart given below illustrates the importance of chemistry in our daily life..

Foods [Starch, sugar, fats, vitamins, proteins] Fuels [Wood, coal, alcohol, petrol] Household and commercial articles [Paper, soap, cosmetics, oils, paints] Textile fabrics [Cotton, wool, silk, linen, rayon, nylon] Drugs and disinfectants [Pencillin, quinine, asprin, sulpha drugs] ..

The branch of chemistry, which deals with energy changes during various physical processes and chemical reactions, is called chemical energetics. All chemical reactions are normally accompanied by energy changes. These energy changes take place because energy is needed to break chemical b..

) the temperature was only 7 F colder than it is today. Since the beginning of the industrial revolution atmospheric concentration of carbon dioxide has increased nearly by 30%. Methane concentration has increased by more than 100% and nitrous oxide by about 15%. These increases have enhanced the h..

Fischer Projection - The intersection of the horizontal and vertical lines represents the chiral center (the chiral carbon). The horizontal lines indicate bonds directed towards the reader. The vertical lines indicate bonds directed away from the reader. By rotating through an angle of 18..

The C-C bond is viewed end on. A point represents the near carbon and three lines radiating from this point represent the bonds linking the three other groups attached to this carbon. A circle represents the other carbon atom that is far away and the three bonds attached to this carbon atom are re..

The time required for the decay of the radioactive element to one half of its original amount is called Half-Life Period . It is denoted by t 1 / 2 . Putting these values in equation (iii), we get ..

Half life of a reaction is defined as the time required for reducing the concentration of a reactant to half its initial value. It is denoted as t 1 / 2..
