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?

They are impure substances with indefinite composition. They retain their physical propertiestheir 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.

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.

Woah that’s a lot to read xd i’ll try though. i’ll get back t you if. i know the andwer
