Zinc is a pure substance. How could you make a mixture from a 1.0-g zinc disc?
A) Place the disc in a beaker with 200 mL of sulfuric acid.
B)Divide the disc into 5 small pieces.
C)Compress the disc into a flatter shape.
D)Coat the disc with another pure substance, such as copper.

D)Coat the disc with another pure substance, such as copper.

Explanation:

To make a mixture of the zinc, simply coat it with another pure substance such as copper. This will result in a mixture.

What then is a mixture?

We can see that coating the copper on the zinc does not alter the physical properties of the metal.

Most times, the copper will wear off and leave behind the zinc.

The metal coated can easily be removed and this signifies just a physical mix.
