The source of energy of stars is nuclear fusion. Fusion reaction occurs at very high temperature, about 10^(7) . Energy released in the process of fusion is due to mass defect. It is also called Q -value. Q = Delta mc^(2), Delta m = mass defect. The binding energy per nucleon of ._(1)H^(2) and ._(2)He^(4) are 1.1 MeV and 7 MeV , respectively. If two deuteron nuclei react to form a single helium nucleus, then the energy released is

The source of energy of stars is nuclear fusion. Fusion reaction occurs at very high temperature, about 10^(7) . Energy released in the process of fusion is due to mass defect. It is also called Q -value. Q = Delta mc^(2), Delta m = mass defect. In a nuclear reaction ._(1)H^(2) + ._(1)H^(2) rarr ._(2)He^(3) + ._(0)n^(1) If the masses of ._(1)H^(2) and ._(2)He^(3) are 2.014741 and 3.016977 amu, respectively. then the Q -value of the reaction is nearly.

Despite the fact that aluminium is a reactive metal, it is a stable in air as well as in water. This is due to the formation of thin layer of oxide on the surface of aluminium metal which makes it passive for further attack. The layer is so useful, that in industry, it is purposely deposited by an electrolytic process called anodising. Reaction of aluminium with oxygen is highly exothermic and is called thermite reaction. 2Al_((s)) +(3)/(2) O_(2(g)) rarr Al_(2)O_(3(s)) Delta_(f) H^(Ө) = -1670 kJmol^-1 This reaction finds application for welding of metal and in the metallurgical extraction of many metals from their oxides. The limitation is that to start the reaction, high temperature is required for which an ignition mixture is required. Which of the following metals cannot be extracted by using Al as a reducing agent ?
