Question

1.One of the first steps in the enrichment of uranium for use in nuclear power plants involves the displacement reaction between UO2 and HF: UO2(g) + 4HF(aq) --> 2H2O(l) + UF4 (s) How many liters of 0.41 M HF with react with 5.007 kg of UO2(MM= 270 g/mol).Please show the steps

One technique used to help confirm the presence of acetylsalcyclic acid is IR spectroscopy. IR spectroscopy utilizes which type of energy from a molecule? A. bond energy B. electronic energy C. vibrational energy D. rotational energy E. nuclear energy

Answer 1

Weight of Doo No.of moles of voz : or Amount of VOZ Molecular weights of voz 33 = 5.007810 g 270 g/mol = 0.01854x162 mol. Given equation is - U0g + (9 4 14 F coas 2 H2O + UF4 e (s). : shi Uv No.of moles of HF = Amount of Camount of 172 . 02 ratio -0.01854x16² mot x 4 mol HF 02 - 1 motto 0.01854 x103 x 4 mol HF. Now, volume of HF used Amount of HE molarity = 0.01854 x163x4 mol HF 0.41 mol/L 3 0.1808 x103 L 180.8 L 180.8L : volume of HE that reacts with 5.007 kg of voz

* In IR, vibrational Energy is used . Answer: C
