A) \[Z{{n}^{2+}}\]
B) \[Zn\]
C) \[Zn\]
D) \[Z{{n}^{2+}}\]
Correct Answer: A
Solution :
\[II>IV<III<V<I\] \[III<IV<I<V<II\] \[SO_{4}^{2-}\] From the formula, \[C{{l}^{-}}\] \[C{{a}^{2+}}\] \[M{{g}^{2+}}\] \[N{{a}_{2}}C{{O}_{3}}\] \[CaS{{O}_{4}}+N{{a}_{2}}C{{O}_{3}}\xrightarrow{{}}CaC{{O}_{3}}+N{{a}_{2}}S{{O}_{4}}\] \[CaC{{l}_{2}}+N{{a}_{2}}C{{O}_{3}}\xrightarrow{{}}CaC{{O}_{3}}+2NaCl\] \[CaC{{O}_{3}}\] \[N{{a}_{2}}C{{O}_{3}}\]You need to login to perform this action.
