$Xe + F_2$ (ratio $1:20$) $\xrightarrow{573 \ K, 60-70 \ bar} A$
What is $A$?

In the solid state,$XeF_6$ exists in which of the following forms?

Which statements among the following are correct about Helium?
$(i)$ Liquid helium is used to sustain powerful superconducting magnets.
$(ii)$ Liquid helium is useful to carry low temperature experiments.
$(iii)$ It is a heavy gas.
$(iv)$ It is a flammable gas.

Assertion : Inert gases are monoatomic.
Reason : Inert gases have stable configuration.

$Xe_{(g)}$ and $F_{2(g)}$ react in the ratio $1:20$ at $573 \ K$ and $60-70 \ bar$ to form $A$. When $A$ is completely hydrolyzed,$B$ and $HF$ are formed. $A$ and $B$ are respectively:
