Question

Câu 2: Cho các oxit : CaO, SO3, FeO, N2O5 , Al2O3 tương ứng ta có các hợp chất sau:

A. Ca(OH)2 , H2SO4 , Al(OH)3, Fe(OH)2, HNO3

B. Ca(OH)2 , H2SO3, Fe(OH)2 , HNO2, Al(OH)3

C. Ca(OH)2 , H2SO4, Fe(OH)3 , HNO3, Al(OH)3

D. Ca(OH)2 , H2SO4, Fe(OH)2, HNO3, Al(OH)3

Answer 1

\(CaO\rightarrow Ca\left(OH\right)_2\\ SO_3\rightarrow H_2SO_4\\ FeO\rightarrow Fe\left(OH\right)_2\\ N_2O_5\rightarrow HNO_3\\ Al_2O_3\rightarrow\left\{{}\begin{matrix}\left(1\right)Al\left(OH_3\right)\\\left(2\right)HAlO_2\end{matrix}\right.\\ \Rightarrow D\)
