Question

A student carries out this chemical reaction in a beaker:

Zn + CuCl2 → Cu + ZnCl2.
After the reaction has come to completion, what should the student expect to find in the beaker?

A.
Zn and CuCl2
B.
Zn, CuCl2, Cu, and ZnCl2
C.
Cu and ZnCl2
D.
ZnCl2 only

Answer 1

Answer:The correct answer is option (C).

Step-by-step explanation:

`Zn+CuCl_2\rightarrow Cu+ZnCl_2`

After the reaction between Zinc and copper(II) chloride, Zinc chloride and copper will be obtained as a product. This reaction occurs because zinc is more reactive than copper which displaces the copper from its aqueous solution.

The student will expect to find copper metal at bottom of the beaker with aqueous solution of zinc chloride.

Hence the correct answer is option (C).
