The iron is oxidised by oxygen in the air. This process is catalysed (faster) in the presence of water and salt.
Fe(s) + O2(g) --> Fe2O3(s) (rust)
Rust is iron oxide, a molecule consisting of iron and oxygen. The mass of the iron in the rust molecules comes from the original nail, but the mass of the oxygen has come from the air. When rust forms on iron, the mass of the iron object is increased by the mass of the oxygen that has combined with some of the iron.
The rust that forms on the nail is actually iron oxide, which has a greater molecular weight than iron. This additional weight from the rust causes the rusty nail to weigh more than the original nail.
This really depends on the concentration of impurities in water. More the impurities, faster it will rust the iron nail. To reduce rusting of any iron the best way is to paint the nail.
A nail rusting is a chemical change. The iron in the nail reacts with water and oxygen to produce rust, a compound with the chemical formula Fe3O2.nH2O.
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.
It either cleans the nail, or makes the nail have rust.
Yes, rust happens to iron nail though it is kept in distilled water.
the nail will get shiny the coke will get rid of all rust on iron. We use coke to clean the rust of our bicycles
It's not just saltwater that makes a nail rust, even water makes a nail rust. Rust is simply oxidation, it happens when oxygen comes into contact with something and creates a chemical reaction and creates "oxides". Iron + oxygen = Iron oxide (red rust on steel)
They combine to form rust. You might be able to guess from what's combining that "rust" is apparently an iron oxide.
Iron present in the nail oxidizes in oxygen to form the iron oxides
Rust is iron oxide, a molecule consisting of iron and oxygen. The mass of the iron in the rust molecules comes from the original nail, but the mass of the oxygen has come from the air. When rust forms on iron, the mass of the iron object is increased by the mass of the oxygen that has combined with some of the iron.
Rust forming on an iron nail is a chemical reaction rather than a mixture. Rust is a compound made up of iron oxide that results from the reaction of iron with oxygen and water in the presence of air.

When an iron nail is placed in vinegar, a chemical reaction occurs that causes the iron to rust. This process is known as corrosion, where the vinegar reacts with the iron to form iron oxide. Over time, the iron nail will continue to corrode and develop a reddish-brown layer on its surface.
it can rust it reacts with atmosphere and reacts with iron oxide then it get rusted
The new product formed when a nail rusts is iron oxide, commonly known as rust. Rust is a reddish-brown compound that forms when iron reacts with oxygen and moisture in the air. It weakens the nail over time and can cause it to deteriorate.
