Ozone layer acts as one of the most important life support systems. The major cause of ozone layer destruction is believed to be the release of chloroflurocarbon compounds. UV radiation cause the chloroflurocarbons to dissociate: CF_2Cl_2 overset(hv)to Cl^(**) + overset(**)(C)F_2Cl A highly reactive chlorine atom is responsible for the decomposition of ozone. Cl^(**) +O_3 to ClO^(**) + O_(2(g)) ClO^(**) + O_((g)) to Cl^(**) + O_(2(g)) Free radicals of chlorine decompose ozone molecules in a chain reaction. The depletion of ozone layer leading to ozone hole has however, been mainly observed in the stratosphere over Antarctica. Special type of cloud called polar stratospheric clouds are formed over Antarctica. These clouds (contain solid HNO 3H,O) play an important role in ozone depletion. The ozone layer is present in:

Calculate a) molality b) molarity and c) mole fraction of KI if the density of 20% (mass / mass) aqueous KI is 1.202" g mL"^(-1) . As density and % by mass is given, so find the mass of solute and solvent (as x % solution contains x g solute in (100 - x) g solvent). Find volume of the solution, by using,, Volume =("Mass")/("Density") Recall the formulae of molality, molarity and mole fraction, to calculate them. Molality =("Mass of solute/ molar mass of solute")/("Mass of solventin kg")
A spinel is an important class of oxides consisting of two types of metal ions with oxide ions arranged in CCP layers. The normal spinel has 1/8 th of the tetrahedral void occupied by one type of metal and one half of the octahedral voids occupied by another type of metal ions such a spinel is formed by Zn^(2+), Al^(3+) and O^(2-) with Zn^(2+) in tetrahedral void. Then the simplest formula of that spinel is Zn_(x)Al_(y)O_(z) then x + y + z is
Answer the following: (a) The top of the atmosphere is at about 400 kV with respect to the surface of the earth, corresponding to an electric field that decreases with altitude. Near the surface of the earth, the field is about 100 Vm^(-1) . Why then do we not get an electric shock as we step out of our house into the open? (Assume the house to be a steel cage so there is no field inside!) (b) A man fixes outside his house one evening a two metre high insulating slab carrying on its top a large aluminium sheet of area 1m^(2) . Will he get an electric shock if he touches the metal sheet next morning (c) The discharging current in the atmosphere due to the small conductivity of air is known to be 1800 A on an average over the globe. Why then does the atmosphere not discharge itself completely in due course and become electrically neutral? In other words, what keeps the atmosphere charged? (d) What are the forms of energy into which the electrical energy of the atmosphere is dissipated during a lightning? (Hint: The earth has an electric field of about 100 Vm^(-1) at its surface in the downward direction, corresponding to a surface charge density = –10^(–9) Cm^(–2) . Due to the slight conductivity of the atmosphere up to about 50 km (beyond which it is good conductor), about + 1800 C is pumped every second into the earth as a whole. The earth, however, does not get discharged since thunderstorms and lightning occurring continually all over the globe pump an equal amount of negative charge onthe earth.)
The decomposition of N_(2)O_(5) in C Cl_(4) at 318K has been studies by monitoring the concentration of N_(2)O_(5) in the solution. Initially the concentration of N_(2)O_(5) is 2.33 mol L^(-1) and after 184 minutes, it is reduced to 2.08 mol L^(-1). The reaction takes placed according to the equation 2N_(2)O_(5)(g)to 4 NO _(2)(g) +O_(2)(g) Calculate the average rate of this reaction in terms of hours, minutres and seconds. What is the rate of proudction of NO_(2) during this period ?
