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
