Aluminum (US spelling) is actually much more reactive than iron, and would corrode faster. In fact, it corrodes so fast that in forms a coating of aluminum oxide on any surface in contact with air. But since the surface is covered, it protects the rest of the metal, and it never corrodes deeper than a fraction of a millimeter. So technically, aluminum corrodes much faster, but much less completely because most of the mass of it is protected by the corroded layer.
Aluminium corrodes faster as it has a higher negative electrode potential than iron, however this is beneficial as the Al2O3 oxide layer forms a protective barrier to inner metal degradation through its self passivating properties. Ductile / Gray iron corrodes at a slower rate, however it is more detrimental to the properties of the metal as there is no protective layer formed and the rust eats further into the metal.
Rust is iron oxide. There is no iron in aluminum. Iron is combined with alloys to prevent stainless steel from rusting. Iron all by itself will corrode or rust faster.
Iron even though aluminum is more reactive than iron.
Not too sure, Do you know?
Iron generally corrodes faster because the oxide layer (rust) does not seal the metal's surface from oxygen like the corrosion on copper does.
I would separate copper strands and iron filings by using a magnet. The iron is magnetic, but the copper is not, so the magnet picks up the iron, but leaves the copper behind.
As pennies are not made of iron, they cannot rust under any circumstances.However they can corrode. The copper shell will produce a green corrosion product, the zinc core can corrode completely away as a transparent water soluble corrosion product. This corrosion will be very slow in plain water (much slower than iron rusts in water) but will be much faster if an acid is added to the water.
nothing will happen as i have done this experiment. I think it is because iron is more reactive than copper, so the copper can't take away the sulphate. but if you added the iron to a copper sulphate solution the product would be iron sulphate this reaction is called displacment.

Contacting the iron powder with an aqueous solution of copper (II) salts will produce a copper coating on iron powder: Iron is higher in the electromotive series than copper and therefore will displace copper from the solution, resulting in copper-coated iron and dissolved iron cations. When all of the surface of the iron powder has been coated with copper, the iron will stop reacting because it no longer has access to the copper ions in solution, the access of the iron being blocked by the layer of copper coating the remaining iron powder.
Steel will corrode as the iron in it is more reactive than copper.
NO!!! Because they are made of copper NOT iron.
Because they corrode and stain on skin contact.

"Rust" is the result of a reaction between iron and oxygen. Copper has no iron in it, so does not rust. It can corrode, though, and yield a bright whitish-blue material.
Iron rusts the fastest among these metals because it is highly susceptible to oxidation when exposed to oxygen and moisture. Zinc-coated steel is less prone to rusting due to the protective layer of zinc that acts as a barrier. Copper does not rust in the same way as iron because it forms a greenish patina called copper oxide when exposed to the elements.
Yes, it would corrode the iron.

Since iron is a more active metal than copper, the iron would replace the copper in the copper sulfate, forming iron sulfate, and releasing elemental copper. The copper will not shape itself into a copper vessel, so eventually, the iron sulfate would leak out of the iron vessel, and eventually, if there is enough copper sulfate, the iron vessel will cease to exist.
The iron nail would stick to a magnet. Copper is not attracted to magnets.
