Solution Steps

Step 1: Determine Solubility Rules for Manganese(II) Carbonate

Manganese(II) carbonate, \( \text{MnCO}_3 \), is a carbonate compound. According to solubility rules, most carbonate compounds are not soluble in water, except for those of alkali metals and ammonium. Since manganese is not an alkali metal, manganese(II) carbonate is not soluble.

Step 2: Determine Solubility Rules for Aluminum Nitrate

Aluminum nitrate, \( \text{Al(NO}_3\text{)}_3 \), is a nitrate compound. According to solubility rules, all nitrate (\( \text{NO}_3^- \)) compounds are soluble in water. Therefore, aluminum nitrate is soluble.

Step 3: Determine Solubility Rules for Ammonium Sulfate

Ammonium sulfate, \( \text{(NH}_4\text{)}_2\text{SO}_4 \), contains the ammonium ion (\( \text{NH}_4^+ \)). According to solubility rules, all compounds containing the ammonium ion are soluble in water. Therefore, ammonium sulfate is soluble.

Final Answer

\[ \boxed{\text{Manganese(II) carbonate: \text{Not Soluble}}} \] \[ \boxed{\text{Aluminum nitrate: \text{Soluble}}} \] \[ \boxed{\text{Ammonium sulfate: \text{Soluble}}} \]
