the correct formulas for ammonium sulfate and ammonium acetate are:

1. aiso4 and al2c2h3o2
2. (nh4)2so4 and nh4c2h3o2
3. nh4so4 and nh4c2h3o2
4. al2so4 and aic2h3

Explanation:

• Ammonium ion is \(NH_4^+\).
• Sulfate ion is \(SO_4^{2 -}\). To balance the charges, for ammonium sulfate, we need 2 \(NH_4^+\) ions for each \(SO_4^{2 -}\) ion, so the formula is \((NH_4)_2SO_4\).
• Acetate ion is \(C_2H_3O_2^-\). For ammonium acetate, the charge of \(NH_4^+\) ( + 1) balances the charge of \(C_2H_3O_2^-\) ( - 1), so the formula is \(NH_4C_2H_3O_2\).

Answer:

1. \((NH_4)_2SO_4\) and \(NH_4C_2H_3O_2\)
