Question

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. Use table 1 and table 2.

Xe(g) + 2 F₂(g) → XeF₄(s)

What is the theoretical mass of xenon tetrafluoride that should form when 118 g of xenon is reacted with 149 g of F₂?
_____ g

What is the percent yield if only 131 g of XeF₄ is actually isolated?
_____ %
