What metal is used in the reaction of metal and air?
Metals in the reactivity series from aluminium to copper react with oxygen in the air to form the metal oxide. Aluminium and Zinc reacts very quickly, Iron reacts slowly at room temperature. Tin, Lead and Copper reacts with Oxygen in air when heated. Silver, Gold and Platinum do not react with Oxygen in air
Which metal is most reactive between copper and aluminium?
Aluminium is more reactive than copper. Aluminium can react with oxygen in the air to form a protective oxide layer, while copper does not readily react with oxygen.
Is corrosion of aluminium metal a physical change or a chemical change?
It is a chemical change. Through corrosion, a chemical reaction has taken place.
Why are food particle preferably packed in aluminium foil?
Aluminium foil donot corrode in atmosphere even if kept for a long time.Actually,aprotective coating of aluminium oxide is formed on the surface of the foil.it stops any further reaction of the metal with air and water.The eatables do not get spoiled.
Why is the frame on a bike made out of alloy and not pure aluminium?
Aluminium alloys are stronger than pure aluminium, which is comparatively soft. Pure aluminium is also considered chemically reactive (thus the layer of aluminium oxide which coats the metal due to oxidation). Pure aluminium hardly exists due to its strong affinity with oxygen in air. In fact, aluminium foils and beverage cans are also alloys of aluminium, with about 92 to 99% of aluminium. So likewise, bike frames are also made of alhminium alloys because of its characteristics of being strong and lightweight.

Is aluminum dull or shiny?
Aluminium metal is shiny. However, it is a very reactive metal with oxygen (air). So if a piece is cut in the lab. you may briefly, (a second or two) see a shiny metal. It then rapidly oxides to form the impervious layer of aluminium oxide , which is dull in appearance. So domestic aluminium pots and pans , whilst made of aluminium, the surface that you see is actually aluminium oxide(dull).
How bauxite is use to benefit the country?
Bauxite is an ore of aluminium. Aluminium is an important metal used in construction of machinery and air-crafts.
Why do metals react with only oxygen when burnt in the air?
Oxygen is the most reactive component of air. So for nearly all metals that burn in air only the oxide is formed. There is one exception magnesium burns in air to form the oxide and also traces of nitride.
What is form instead when magnesium is burnt in air?
It forms magnesium oxide. :)
How does your nose provide evidence that particles exist?
If you polish a piece of aluminium with a cloth you can smell the metal. this is because particles from the aluminium have gone into the air. i don't know if this is the proper answer, but i think it is a reason.
Is trans metal reactive or not?
I don't know what you mean by "trans metal".Transition metals vary in reactivity from platinum and gold (almost inert) to zinc (pretty reactive), though less so than, say, aluminium (you may not think of aluminium as reactive, but that's because it's so reactive it instantly reacts with oxygen in the air to form a thin transparent layer of aluminium oxide, which is pretty non-reactive) or magnesium or sodium.
Is corrosion of aluminium metal a physical change or a chemical change?
It is a chemical change. Through corrosion, a chemical reaction has taken place.
How long those it take aluminum to decompose?
Instantaneously. Elemental Aluminium metal reacts immediately with oxygen in the air, to form aluminium oxide. Aluminium oxide is a very stable compound, and so does not allow the underlying aluminum metal any further reaction. If you have aluminium pots and pans at home, then you are actually touching the aluminium oxide, because the underlying aluminium has already reacted with atmospheric oxygen .
Why is that a piece of aluminium foil exposed to moist air does not corrode even though aluminium is more reactive than iron which easily rust?
Aluminium reacts very rapidly with the oxygen in the air to form a thin film of aluminium oxide covering the entire surface of the aluminium in the foil. This surface is invisible to the eye. Aluminium oxide is very resistant to chemical processes, like corrosion. It protects the aluminium underneath very well, so aluminium does not corrode in moist environments. If the aluminium is scratched, an new aluminium oxide film forms immediately, protecting the scratched part. Iron does not form a protective skin, because iron oxide has different chemical properties to aluminium oxide and is not able to protect the iron.
Does aluminium burn in air?
Aluminium does not burn in air at room temperature. However, when heated to high temperatures, typically above 600 degrees Celsius, it can react with oxygen in the air to form aluminium oxide and release heat in the process.
