$Xenon$ reacts best with

$XeF_2$ is hydrolyzed in the presence of a small amount of water. What are the gaseous products formed?

The complete hydrolysis of $XeF_{6}$ results in the formation of

$0.1 \ mol$ of $XeF_6$ is treated with $1.8 \ g$ of water. The product obtained is

$Xe_{(g)} + 2 F_{2(g)} \xrightarrow[7 \text{ bar }]{873 \text{ K}} XeF_{4(s)}$
The ratio of $Xe : F_2$ required in the above reaction is
