What happens to the copper atoms of the penny in gold penny lab?
basically, the zinc electrons in the NaOH solution coat the copper penny and then when you wave it over a Bunsen burner, the two metals form an alloy (a homogeneous mixture with two or more elements) and make brass, not gold.
Why did the penny turn gold when heated in the burner in the burner flame?
When a penny is heated in a flame, the copper metal reacts with oxygen in the air to form copper oxide. Copper oxide has a black color, but when it is heated at high temperatures, it can react with carbon in the flame to form a thin layer of elemental gold on the penny's surface, giving it a gold color.
Why did the penny turn a silver color?
In 1943 the US Mint briefly replaced the copper penny then in use with a steel penny, due to the wartime copper shortage.
What coin is made out of copper?
The penny is made out of copper.
Can you turn a penny into gold. if not explain?
In practice, no. In theory, you could break down the copper atoms into hydrogen, and fuse them into gold. This would take an insane amount of time an energy, so if you have a supergiant star and a few hundred million years, you can turn anything into gold.
Can gold be scratched by a penny?
No, gold is a much harder metal than copper, which is found in pennies. Therefore, a penny is not capable of scratching gold.

Can a copper penny and a copper large bell have the same density?
Yes, both a copper penny and a copper large bell can have the same density because they are made of the same material, copper. Density is a physical property of a substance and is determined by the mass of the substance divided by its volume. As long as the copper used in both the penny and the large bell is of the same purity and composition, they can have the same density.
Are pfennigs a gold considered gold?
A pfennig is a German "penny" and would not have gold in it. Would normally be brass or copper. If shinned up can look much like gold
Can a copper penny and a large copper bell have the same density?
Yes because the element density stays the same! Ex: If you cut a gold brick & you have a simple gold coin they're still gold so they still have the same density!
What coin is made out of copper?
