I-131(T= 8.05days) is a product of Uranium-235. If the fission yield is 0.50%: 1. Determine the mass of Uranium-235 that needs to be used so as to obtain 7.4 ×10^10 Bq of I-131 after 2 days of irradiation.
2. What will be the radioactivity of the radionuclide 2 days after irradiation? Take effective area of the fission of Uranium-235 to be 577 barns and the available neutron flux to be 10^12 n/cm^2/s

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
