Question

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

Answer 1

Answer: General equation for Double Replacement Reactions is:

AY+BX→BY+AX

Step-by-step explanation:

2NaCl+CuSO4→Na2SO4+CuCl2

2NaOH+CuSO4→Na2SO4+Cu(OH)2

2Na3PO4+2CuSO4→Cu3(PO4)2+3Na2SO4

NaCl+AgNO3→AgCl+NaNO3

2NaOH+2AgNO3→2NaNO3+Ag2O+H2O

Na3PO4+3AgNO3→3NaNO3+Ag3PO4
