Guys please help me
Once who help me I will mark as a briently.

Answer 1

`CaSO_(4)`,
`NaNO_(3)`,
`MgO`,
`K_(2)CO_(3)`,
`(NH_(4))_(2)S`,
`H_(2)SO_(4)`,
`Mg(NO_(3))_(2)`, and
`SiO_(2)`.

Step-by-step explanation:

With all of these salts, you have to match the charge of the anion and the cation so that they cancel each other out, making a neutral compound. The charges of each element can be figured out by counting on the periodic table, but you have to memorize or look up the charges of polyatomic ions.
