A compound containing xenon and fluorine, Xex,Fy, was producedby shining bright sunlight on a gaseous mixture of 0.439 g of Xeand excess fluorine. If all the xenon reacts, and 0.693 grams ofthe compound are formed, what is the empirical formula of thecompound?
A 0.158 gram sample of a salt, comprised of barium and one ofthe halide ions, was dissolved in water, and an excess of sulfuricacid was added to form barium sulfate, BaSO4. After filtering anddrying, the solid BaSO4 weighed 0.124 grams. Determine the identityof the halide and the formula of the barium halide.
