. (_92^235)U is a fissile isotope of uranium, used in the atomic bomb dropped on Hiroshima in 1945. The critical mass is 56 kg. The primary isotope is not fissile and had to be removed by a process which required synthesis of UF6, a gas. How much 235UF6 was required to produce a critical mass of the element? [Molar masses: U, 235.0439 g; F, 18.9984 g]

Uranium (VI) fluoride was sublimed, ionized, and separated to extract U-235 isotope from bulk uranium by an Iranian laboratory. The enthalpies of formation for solid and gaseous UF6 are –2137 KJ/mole and –2113 KJ/mole, respectively. The sublimation process is given by: UF6 (s) = UF6 (g). The amount of energy needed to sublime 9.886 Kilograms of UF6 , in Kcal is:

Uranium-235 is a rare isotope of uranium that can be used for power plants as well as bombs. Its nucleus decays to a thorium-231 nucleus by emitting an α-particle. Uranium has atomic number 92, and thorium has atomic number 90. A nuclear reaction such as this is written using the following notation: 235U → 231Th + α Mass number is the number of protons plus the number of neutrons. It is the top number in this notation. In these nuclear...

1. In order to prepare fuel for a nuclear reactor it is necessary to increase the percentage of 2350 (the isotope that undergoes fission) in the natural ore relative to the percentage of 238U (the most abundant isotope in uranium ores). This is done by converting the uranium isotopes into UF: (which is a gas at 298 K) and separating them by effusion. a) Which gas will effuse faster (235UF8 or 238UF.)? atomic mass of 2350 - 235.0439 amu; atomic...
