Answer:
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?
- They are impure substances with indefinite composition.
- They retain their physical properties
- their constituents reacts differently to changed conditions
- They can easily be separated into constituents by physical methods.
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.
