Answer: Cu(s) + 2AgNO3(aq) → Cu(NO3)2(aq) + 2Ag(s)
Explanation:
As the name implies, a displacement reaction involves the displacement of an atom by another atom. The general displacement response model is
A + B-C → A-C + B
Assume A is more reactive than B.
A and B must be:
Halogens with a cation.
Metals with C as an anion.
