By "the" penny, I'm assuming that you mean a penny that has been treated with zinc and sodium hydroxide, and then heated over a flame.
To remove the brass plating, you can create friction on the surface of the coin that wears it away, reverting it back to its original copper color.
What else can I help you with?
Brass mimics copper or gold?
Gold, definitely. How about fixing this question as to what type of "brass" There is Yellow brass 60% Copper 40% Zinc and the more common red brass 85% copper and 15% Zinc then there is Muntz metal and Bronze thus BRASS = COPPER as there is NO gold content in "Brass"
Why are the pins on a plug made of brass not copper?
because brass is generally tarnish resisant so it does not discolours easily and also because brass is not such expensive as copper <<>> The pins are make of brass because it is a harder metal than copper and will wear better through use over its lifetime.
Which year was brass invented?
Brass is an alloy of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses with varying properties. Although forms of brass have been in use since prehistory, its true nature as a copper-zinc alloy was not understood until the post medieval period because the zinc vapor which reacted with copper to make brass was not recognized as a metal. The King James Bible makes many references to "brass". The Shakespearean English form of the word 'brass' can mean any bronze alloy, or copper, rather than the strict modern definition of brass. The earliest brasses may have been natural alloys made by smelting zinc-rich copper ores.

After doing the expt.of converting a copper penny to silver and gold colored i.e brass penny I have a question.Is it possible to convert the brass penny back to copper again?
This might be possible with a ton of vinger or lemons, and a lot a scrubing. I am not a 100% sure if it coule happen but it is worth trying. That was a great question. That would be a great experiement to try.

Does copper and brass have the same density?
No, copper and brass do not have the same density. Copper has a density of around 8.96 g/cm³, while brass, which is an alloy of copper and zinc, has a density that varies depending on the specific composition. Generally, brass has a lower density than copper due to the addition of zinc.
