Vedclass · Answer

(B) $BeSO_4$ is soluble in water due to the high hydration energy of the $Be^{2+}$ ion,which overcomes the lattice energy. Thus,the statement is correct.$(B)$ $BeO$ is an amphoteric oxide because it reacts with both acids and bases. Thus,the statement is correct.$(C)$ Heating $CaCO_3$ at $1070-1270 \ K$ yields $CaO$ and $CO_2$,not $CO$. The reaction is: $CaCO_3 \xrightarrow{\Delta} CaO + CO_2 \uparrow$. Thus,the statement is incorrect.Therefore,the correct statements are $A$ and $B$.

Identify the correct statements from the following.
$(A)$ $BeSO_4$ is soluble in water.
$(B)$ $BeO$ is an amphoteric oxide.
$(C)$ $CO$ can be obtained by heating $CaCO_3$ at $1070-1270 \ K$.
