Concept explainers
For many years after they were discovered, it was believed that the noble gases could not form compounds.
Now we know that belief to be incorrect. A mixture of xenon and fluorine gases, confined in a quartz bulb and placed on a windowsill, is found to slowly produce a white solid. Analysis of the compound indicates that it contains 77.55% Xe and 22.45% F by mass.

- The first laboratory experiments to produce compounds containing noble gas atoms aroused great excitement, not because the compounds might be useful but because they demonstrated that the noble gases were not completely inert. Since that time, however, important uses have been found for a number of noble gas compounds. For example, xenon difluoride, XeF2, is an excellent fluorinating agent (a substance that adds fluorine atoms to other substances). One reason it is preferred over certain other fluorinating agents is that the products of its fluorinating reactions are easily separated from the gaseous xenon. The following unbalanced equation represents one such reaction: S3O9 + XeF2 → S2O6F2 + Xe Balance this equation. What is the minimum number of moles of XeF2 necessary to react with 4 moles of S3O9? What is the maximum number of moles of S2O6F2 that can form from the complete reaction of 4 moles of S3O9 and 7 moles of XeF2?
