For each of the four single-displacement reactions, describe what happened in rachel well. if a chemical reaction occured, write a balanced equation for it. then using the a, b symbols, write a general equation for a single-displacement reaction.

Explanation:

Single replacement:

It is the reaction in which one elements replace the other element in compound.

General equation:

AB + C → AC + B

1) zinc and Copper sulfate

Zn + CuSO₄   →   ZnSO₄ + Cu

Zinc is more reactive than copper it displaces the copper from copper sulfate and form zinc sulfate.

2) Aluminium and Copper sulfate

2Al + 3CuSO₄   →  Al₂(SO₄)₃ + 3Cu

Aluminium is more reactive than copper it displaces the copper from copper sulfate and form aluminium sulfate.

3) Zinc and silver nitrate

Zn + 2AgNO₃ → Zn(NO₃)₂ + 2Ag

zinc is more reactive than silver it displaces the silver from silver nitrate and form zinc nitrate.

4) copper and silver nitrate

Cu + 2AgNO₃  → Cu(NO₃)₂ + 2Ag

copper is more reactive than silver it displaces the silver from silver nitrate and form copper nitrate.
