Question

The uranium minerals found in nature must be refined and enriched in ^235 U before the uranium can be used as a fuel in nuclear reactors. One procedure for enriching uranium begins with the reaction of natural UO_2 with HF to form UF_4, which is then converted into UF_6 by reaction with fluorine: UO_2 (g) + 4 HF(g) rightarrow UF_4 (g) + 2 H_2 O(l) UF_4 (g) + F_2 (g) rightarrow UF_6 (g) a. How many kilograms of HF are needed to completely react with 2.25 kg of UO_2? b. How much UF_6 can be produced from 830 g of UO_2?
