Believe it or not, aluminum is technically more reactive than iron. However, when aluminum is exposed to air, it almost instantly forms a microscopic layer of aluminum oxide (Al2O3) which protects the rest of the aluminum from any further reaction. Iron doesn't do this, and therefore corrodes unevenly, making it unsuitable for certain applications.
Because Aluminium forms a protective layer when it gets together with Oxygen:)
Yes, and violently so.
Magnesium is a stronger reducing agent than iron. The magnesium has a stronger tendency to take up the oxygen to form magnesium oxide than iron. Iron misses out on the oxygen until the magnesium is all used up.
The list begins with the more active (anodic) metal and proceeds down the to the least active (cathodic) metal of the galvanic series. A "galvanic series" applies to a particular electrolyte solution, hence for each specific solution which is expected to be encountered for actual use, a different order or series will ensue. In a galvanic couple, the metal higher in the series (or the smaller) represents the anode, and will corrode preferentially in the environment. 1. Magnesium 2.

It seems unlikely that dolomite would react with iron to any significant degree. Dolomite is calcium magnesium carbonate; both calcium and magnesium are higher on the activity series than iron.
Iron and magnesium burn in air under the right circumstances becasue they combine rapidly with oxygen. (Fire is just the rapid combination of oxygen or another oxidizer, wiht a fuel.) Oxygen is only about 20% of air. If you provide pure, 100%, oxygen under the same circumstances, there is more oxygen to combine with the iron or magnesium, so they can burn faster.
Yes, and violently so.
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.
The combination of moisture, oxygen and salt, especially sodium chloride, damages metal worse than rust does. This combination corrodes, or eats away at, the metal, weakening it and causing it to fall apart. Saltwater corrodes metal five times faster than fresh water does and the salty, humid ocean air causes metal to corrode 10 times faster than air with normal humidity. Bacteria in ocean water also consumes iron and their excretions turn to rust.
Magnesium is a stronger reducing agent than iron. The magnesium has a stronger tendency to take up the oxygen to form magnesium oxide than iron. Iron misses out on the oxygen until the magnesium is all used up.
Sodium is more reactive than either magnesium or iron.
No, as magnesium is more reactive, and would 'keep' the nitrate.
yes! it does because magnesium is higher in reactivity series than iron , so the magnesium atom would displace or push out the iron atom from the compound and join with chloride, leaving the pure iron out of the compound Mg + FeCl2 -- MgCl2 + Fe
iron travels faster
In a short answer No. But I can't really explain why.
NO!!! Because they are made of copper NOT iron.
Fe + MgSO4 --> FeSO4 + Mg Fe(iron)is more reactive than mg( magnesium) ........ therefore iron will displace magnesium....... hence it is a displacement reaction.............
Magnesium(s) + Iron(s) + HCl(aq) -> MagnesiumChloride(aq) + Hydrogen(g) + Iron(s)Iron will not react with hydrochloric acid as magnesium is more reactive than iron , so magnesium will react with hydrochloric acid to give salt and hydrogen gas while iron is deposited.METAL + ACID -> METAL SALT + HYDROGEN GAS
