Question

Write 5 double displacement reactions

Answer 1

Answer:

Double displacement reactions may be classified into several categories, including counter-ion exchange, alkylation, neutralization, acid-carbonate reactions, aqueous metathesis with precipitation (precipitation reactions), and aqueous metathesis with double decomposition (double decomposition reactions).

Answer 2

Zn(s) + Cu2+(aq) → Zn2+(aq) + Cu(s)

Zn(s) → Zn2+(aq) + 2e-

Cu2+(aq) + 2e- → Cu(s)
