actually, it becomes darker. the nail will turn a brownish-blackish color.
the iron combines with oxygen, forming iron III oxide, or Fe2O3
The most obvious one is when it rusts. Rust is the oxidization of iron.
Chemical change, oxygen binds with iron.
When a nail rusts, iron in the nail reacts with oxygen in the air to form iron oxide (rust), which has a greater mass than iron alone. As a result, the overall mass of the nail increases when it rusts because the mass of the iron in the nail combines with the mass of the oxygen in the air to form iron oxide.
When an iron nail rusts, it actually gains mass. Rusting is a chemical reaction between iron, oxygen, and moisture, producing iron oxide (rust). During this process, the iron combines with oxygen from the air, which adds to the overall mass of the nail. While rusting is not a form of burning, it does involve an oxidation reaction similar to combustion.
The plural of rust is rusts. As in "a nail left in the open rusts easily".
a nail rusts
because its a chemical reaction
a penny
No. Iron rusts but it is not biodegradable.
When a part rusts, it typically becomes heavier in weight because rust is formed when iron reacts with oxygen in the presence of moisture, adding weight to the original material.
Salt water.
when a nail rusts it is because the nails are made of iron the rusts forms when the iron nail comes in contact with rain and oxygen at the same time which forms rust over time more water comes in contact with the nail and more rust is formed the word equation for this change: Iron+Water+Oxygen-->iron oxide(rust)+Hydrogen The chemical equation for this change 2Fe+H2O+O-->Fe2O3+H hope this helped
As the rust expands the nail will get slightly bigger then reach a point when starts to disintergrate.
yes, it's just that the metal becomes a new compound. It wouldn't be metal anymore.
Outside on wet soil
Rusting is an oxydation reaction.
