Question

Which of the following pairs will give displacement reactions?

(a) NaCl solution and copper metal

(b) MgCl2 solution and aluminium metal

(c) FeSO4 solution and silver metal

(d) AgNO3 solution and copper metal

​

Answer 1

Answer:

(d) AgNO3 solution and copper metal

Step-by-step explanation:

Copper (Cu) being more reactive than silver (Ag), displaces silver from silver nitrate (AgNO3) to form copper nitrate

2AgNO3 + Cu → Cu(NO3)2+ 2Ag

Answer 2

Answer:

D

Step-by-step explanation:
