yes, it's just that the metal becomes a new compound. It wouldn't be metal anymore.
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.
Salt water.
No, a nail does not become lighter when it rusts. Rust is actually iron oxide that forms on the surface of the nail, which can increase the overall weight of the nail due to the addition of oxygen atoms from the rusting process.
As the rust expands the nail will get slightly bigger then reach a point when starts to disintergrate.
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.
Outside on wet soil
When an iron nail rusts, it gains mass. This process involves the chemical reaction between iron, oxygen, and moisture in the environment, resulting in the formation of iron oxide (rust). The added mass comes from the oxygen in the air and water that combine with the iron, leading to an increase in the total mass of the rusted nail. Thus, the overall mass of the nail increases as it rusts.
Rusting is an oxydation reaction.
