Aluminum and Iron are both elements. You can't use one to make another. Well, not without nuclear chemistry.
Did you mean, why not use aluminum to make steel?
The answer is, in a way, we do. Steel is an alloy of iron and carbon or other elements. Aluminum alloys are widely used, in applications such as aircraft and car engines. However, aluminum alloys have different properties than steel - they tend to be more susceptible to heat and not always have the same tensile strength. So engineers have to keep these differences in mind.
Yes but depending on its use
lighter
Aluminium forms Al2O3 (a coating which prevent further reaction to take place as the hydrogen ions (H+) will not be in contact with AL+3
oxidation takes place (rusting)
the aluminium is split with the sulphate ion. this leaves the sulphate on its own with a charge. the copper then takes the place of the aluminium turning the charge of the sulphate ion to neutral, this leaves the aluminium and copper sulphate.
no its chemical. physical changes is where the object chemical matter is not altered. ex- cuting a piece of paper is physical because you still have a piece of paper but burning the paper is chemical because a chemical change has taken place.
The melting is important.
Aluminium forms a thin layer of oxide on the surface which stops any further rusting taking place.

in a metal when their is presence of oxygen and water rusting takes place
Depending on the material that the gates are made of, rust is a potential issue. If they are made from wood rusting won't take place. Additionally, there are many kinds of treatment for metals that can delay or even prevent rusting from happening.
A chemical change has taken place
Water and oxygen are needed.
Make sure the metal chains stay in a rain-proof area (for example, a dry place with a roof top to prevent rain from rusting the metal chain).
Plz answer
No. Acid can be used to remove acid, but that is because the rust dissolves in acid. It does not prevent the metal from rusting in the first place. Just save the vinegar for the next time you eat fish and chips. Also, all homeless people stink of rotten fish and dead people.
When Iron became in contact with water and oxygen or other strong oxidants or acids the rusting took place. The rusting is an electrochemical process which started with the transfer of electrons form iron to oxygen. If salt is present then it also accelerate the rusting process.
The best place to sell aluminium near Winnsboro 75494 is Sulphur Springs, TX.
Oxygen is a very important agent needed for rusting and decaying to take place. Oxygen binds with the surface and creates water while breaking down the substance.
