$BeF_{2}$ is prepared by thermal decomposition of

Answer:

Solution:

Beryllium fluoride ( $B e F_{2}$ ) is prepared by the thermal decomposition of ammonium tetrafluoroberyllate, $(N H_{4})_{2} B e F_{4}$ .

The reaction is:

$(N H_{4})_{2} B e F_{4} (s) Δ B e F_{2} (s) + 2 N H_{3} (g) + 2 H F (g)$

This method is commonly used for the synthesis of anhydrous beryllium fluoride.
