Chapter 9, Problem 65(choose chapter or problem)
Although they were formerly called the inert gases, at least the heavier elements of Group 8 do form relatively stable compounds. For example, xenon combines directly with elemental fluorine at elevated temperatures in the presence of a nickel catalyst. Xe(g) _ 2F2(g) S XeF4(s) What is the theoretical mass of xenon tetrafluoride that should form when 130. g of xenon is reacted with 100. g of F2? What is the percent yield if only 145 g of XeF4 is actually isolated?
