Rust is the name normally given to iron oxide, a compound formed when iron or steel is exposed to oxygen. Pennies, or cents in the US (and Canada until 2012) are made from copper and other non-ferrous metals so by definition they don't form rust. However some countries' "copper" coins are actually made of steel with a thin copper coating. If the coating is damaged oxygen can cause the underlying steel to rust although the copper itself does not.
However, copper can and does react with oxygen and other materials over time, but usually it's a much slower process than what happens with a ferrous metal. In the case of coins, the most common reaction produces a greenish patina called verdigris; it's normally copper carbonate but in proximity to seawater verdigris can contain copper chloride.

How does iron rust a penny?
A British penny is not normally affected by rusting .
What happens to a copper?
It starts rusting when water keeps on touching it.:)
How can a penny rust the faster?
A penny can rust faster when exposed to moisture and oxygen, which contribute to the oxidation process that forms rust on the surface of the penny. Factors like humidity, presence of salts, and acidic environments can also accelerate the rusting process.
Are VW cars dipped in wax?
Yes; the wax dip keeps the hidden parts from rusting.
Why are water pipes galvanised?
To control rusting. Galvanizing means that a layer of zinc metal is placed on top of steel. Zinc forms a protective layer that keeps the steel from rusting.
Will sprite make a penny rust?
Yes water makes a penny rust faster in water because the particles are nore affective and the coke does not have near as many particles as water well good luck with the expirementing that project!!!!!!!!
Why doesn't a penny rust?
Because it is not made of iron. It does however oxidize (the same process as iron rusting). This copper "rust" is the darker brown colour that a penny acquires as it gets older.
What is the value of 1889 Indian penny?
hold on to it, value keeps increasing
How does a penny affect water?
Supposidly, a bag of water with a penny in it keeps flys away. However, you really don't need the penny and a half filled bag of water will catch some flys.
What keeps water on a penny?
Surface tension keeps water on a penny even when it goes over the surface of the penny and you think it would spill over the edge due to gravity. I believe surface density is accomplished due to the fact that the hydrogen bonds, for that scale, is stronger than the force of gravity. For more information look at the Related Links below.
What are the chemical and the principle involved in preventing rusting?
Anything that keeps oxygen (air) away from iron will prevent rust - galvanize, paint, oil, etc.
What is the function of heme in hemoglobin?
Heme is what keeps iron from rusting in our blood, which combines with globin to make hemoglobin, which is the thing in our red blood cells that carries oxygen.
