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
In well 1A there was a chemical reaction which turned the zinc black, while the copper sulfate was still blue.
AX + B → A + BX
Zn + CuSO4 → ZnSO4 +Cu
• aluminum – Al copper sulfate – CuSO4
In well 2A there was no reaction between the aluminum and copper sulfate. The aluminum floated and there was no change in color, gas released, or precipitates which identifies that there was no reaction.
AX + B → A + BX
NO REACTION
• zinc – Zn silver nitrate – Ag(NO3)
In well 3A there was a reaction between the zinc and silver nitrate. The zinc turned black as well as the liquid silver nitrate which identifies that there was a chemical reaction taking place.
AX + B → A + BX
Zn + Ag(NO3) → Zn(NO3) + Ag
copper – Cu silver nitrate – Ag(NO3)
In well 4 there was a reaction between the solid copper pieces and the solution silver nitrate. The copper rusted and changed to a dusty black-grayish color. This change in color identifies that a chemical reaction just took place.
AX + B → A + BX
Cu + Ag(NO3) → Cu(NO3) + Ag
