NettetThus, the stability of the decomposition product metal oxide decreases, as close packing is not possible. Hence, the stability of the carbonate increases. Thus, among the given carbonates, the order of thermal stability is BaCO 3>CaCO 3>MgCO 3.
NettetCorrect options are A) , B) and D) (A) BeCO 3 has lowest thermal stability. It decomposes to give BeO and CO 2. Hence, it is placed in the atmosphere of CO 2 which prevents decomposition. Thus, the option A is correct. (B) B dissolves in alkali to form [Be(OH) 4] 2−. Be 2++4OH −→[Be(OH) 4] 2− Thus, the option B is correct. bordiga chiot montamaroNettetPreview this quiz on Quizizz.
