To solve the problem, we will follow these steps: ### Step 1: Identify the Reactants We start with ammonium sulfate, which has the formula \( \text{(NH}_4)_2\text{SO}_4 \), and sodium hydroxide (NaOH). ### Step 2: Write the Reaction When sodium hydroxide is added to ammonium sulfate, a double displacement reaction occurs. The reaction can be written as: \[ ...
