Question

Below are two chemical equations:

Zn (s) + CuSO (aq) → ZnSO (aq) + Cu (s)

Pb (s) + CuCl (aq) → PbCl (aq) + Cu (s)

Why does copper get separated from its compound form in both the cases?

• A. Zinc and Lead are unstable in element form.
• B. Copper compouncis break down under high pressure.
• C. Zinc and Lead more reactive than Copper.
• D. Copper is more reactive thar Zinc and Lead.

Answer 1

Answer:

C. Zinc and Lead more reactive than Copper.

• The phenomenon observed in the given chemical equations is a displacement reaction. • In a displacement reaction, a more reactive metal displaces a less reactive metal from its compound (usually in an aqueous solution).
