why beryllium carbonate is kept in the atmosphere of carbon dioxide?answer as soon as possible

Solution

Dear student,

Due to least electropositive character or least basicity of Be, BeCO₃ is less stable and hence decomposes to give BeO and CO₂.
BeCO₃→BeO + CO₂
Since the decomposition reaction is reversible, therefore, to increase the stability of BeCO₃ or to reverse the above equilibrium, BeCO₃ is kept in an atmosphere of CO₂.

Regards
