Question

9.) copper (ii) sulfate (1 point)○ $ce{cu_{2}s_{2}}$○ $ce{cuso_{4}}$○ $ce{cu_{2}(so_{4})_{2}}$○ $ce{cus}$

Explanation:

Brief Explanations

Copper (II) has a +2 charge ($\text{Cu}^{2+}$), and the sulfate ion has a -2 charge ($\text{SO}_4^{2-}$). To form a neutral ionic compound, one $\text{Cu}^{2+}$ balances one $\text{SO}_4^{2-}$.

Answer:

B. $\text{CuSO}_4$
