Paper-I (Nuclear & Radiochemistry)
1. Boron is used as a rocket fuel, the enthalpy of combustion of boron to form B 2O3 being – 1278 kj/mol.Find the
energy of formation of one molecule of B2O3 in eV.
2. The nucleus, and (b) the ratio of the axes b/a. Take the mean radius to be given by R = 1.4 A v3 F.
3. It is known that 1 g of
