1. For Part 2: Single-Displacement Reactions: For each of the four single-displacement reactions, describe what happened in each well. If a chemical reaction occurred, write a balanced equation for it. Then using the A, B symbols, write a general equation for a single-displacement reaction.
Here are the chemical formulas of the reactants for each reaction:
• zinc – Zn copper sulfate – CuSO4
• aluminum – Al copper sulfate – CuSO4
• zinc – Zn silver nitrate – Ag(NO3)
• copper – Cu silver nitrate – Ag(NO3)

2. For Part 3: Double-Displacement Reactions: For each of the double-displacement reactions, describe what happened in each well, including the colors of any products that formed. If a chemical reaction occurred, write a balanced equation for it. Then using the A, B symbols, write a general equation for a double-displacement reaction.
Here are the chemical formulas of the reactants for each reaction:
• sodium chloride – NaCl copper sulfate – CuSO4
• sodium hydroxide – NaOH copper sulfate – CuSO4
• sodium phosphate – Na2HPO4 copper sulfate – CuSO4
• sodium chloride – NaCl silver nitrate – AgNO3
• sodium hydroxide – NaOH silver nitrate – AgNO3
• sodium phosphate – Na2HPO4 silver nitrate – AgNO3
