Write the chemical equations involved in the preparation of the following:
(a) `XeF_4 ` (b) `H_3PO_3`

Explanation

Chemical involved in the preparation of `XeF_4` and `H_3PO_3` are given below :
(a) `Xe + 2F_2 underset("1 bar ") overset(873K) to XeF_4`
(b) `underset(1:5 " ratio " ) (P_4O_6 ) + 6H_2O to 4H_3PO_3` (Phosphorous acid )
