Question
1) ZnSO4 would it be Zn(SO4)
does the polyatomic ion always have to have ( ) ?
2) Is Ba(SO4) right?
since Ba is 2+ and SO4 is 2- right?
3) In a net ionic equation for BaCI2 would it become Ba ^(2+) + 2CI or Ba ^(2+) + CI2 ?

For #2 did I write it correctly?

Also would Sr3(PO4)2 be right?

<b>Parentheses are required ONLY when the subscript for SO4 is not 1. In ZnSO4 the parentheses are not needed.</b>
2) Is Ba(SO4) right?

<b>Yes, Ba(SO4) is right but the parentheses are not needed. </b>
3) In a net ionic equation for BaCI2 would it become Ba ^(2+) + 2CI or Ba ^(2+) + CI2
<b>I think you mean BaCl2 (barium chloride) since I am not familiar with CI2. The ionization of BaCl2 is to Ba^+2 and 2Cl^-</b>

Cl is chlorine. That is a "see""ell" and not a "see""eye".
