2. Part 3: Double-Displacement Reactions: For each double-displacement reaction, 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 use the A, B symbols to 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 – Na3PO4

copper sulfate – CuSO4

• sodium chloride – NaCl

silver nitrate – AgNO3

• sodium hydroxide – NaOH

silver nitrate – AgNO3

• sodium phosphate – Na3PO4

silver nitrate – AgNO3
