1. Part 2: Single-Displacement Reactions: For each of the four single-displacement reactions, write a balanced equation. Assume that there will be a reaction even if you didn't see one in the lab. General equation for single-displacement reactions:

A + BX → AX + B

Ion charges: (Zn2+, Cu2+, SO42-, Al3+, Ag1+, NO31-) Answer: • zinc [Zn] + copper sulfate [Cu(SO4)] (2 points) ◦

Balanced equation: … + … → …. + …. • aluminum [Al] + copper sulfate [Cu(SO4)] (2 points) ◦

Balanced equation: … + … → …. + …. • zinc [Zn] + silver nitrate [Ag(NO3)] (2 points)

◦ Balanced equation: … + … → …. + …. • copper [Cu] + silver nitrate [Ag(NO3)] (2 points) ◦ Balanced equation: … + … → …. + ….

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

- zinc [Zn] + copper sulfate [Cu(SO4)
Balanced equation:Zn + Cu(SO4) → Zn(SO4) + Cu

- aluminum [Al] + copper sulfate[Cu(SO4)]Balanced equation:2Al + 3Cu(SO4) → Al2(SO4)3+ 3Cu

- zinc [Zn] + silver nitrate [Ag(NO3)]Balanced equation:Zn + 2Ag(NO3) → 2Ag + Zn(NO3)2

- copper [Cu] + silver nitrate [Ag(NO3)]
Balanced equation:Cu + Ag(NO3) → Cu(NO3) + Ag
