1.	Assertion (A) : Beryllium carbonate is kept in the atmosphere of carbon dioxide. Reason (R) : Beryllium carbonate is unstable and decomposes to give beryllium oxide and carbon dioxide.
Answer» Both A and R are correct and R is the correct explanation of A. Both A and R are correct but R is not the correct explanation of A. Both A and R are not correct. A is not correct but R is correct Solution :BeO is more stable dueto SMALL size asnd strong polarizing power of `Be^(2+)`. As BeO is stable and `BeCO_(3)` is unstable. When it is kept in the ATMOSPHERE of `CO_(2)` a reversible process occurs and stability of `BeCO_(3)` increases.
