  • 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.

In the following questions a statement of Assertion (A) followed by a statement of Reason (R) is given. Choose the correct option out of the choices given below each question.

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.
(i) Both A and R are correct and R is the correct explanation of A.
(ii) Both A and R are correct but R is not the correct explanation of A.
(iii) Both A and R are not correct.
(iv) A is not correct but R is correct.

Answers (1)

The answer is the option (i) Both A and R are correct and R is the correct explanation of A.BeO is more stable due to small size and strong polarising power of Be^{2+}. Since BeO is stable and BeCO_3 is unstable, when kept in atmosphere of CO_{2} a reversible process occurs and stability of BeCO_3 increases
