Actually, aluminum is very reactive. It is so reactive that it forms thin layers of oxide on its surface at room temperature. This thin film protects the metal underneath from further oxidation. Some aluminum parts are " nitrided" for even better protection. This is very popular with tools and cooking pans.

What is the molecular size of aluminum stearate?
Aluminum stearate has a molecular weight of 876.0 Aluminum stearate is used in cosmetics, often as an emulsifier. The aluminum stearate comes from stearic acid.
Which acid or alkali will dissolve aluminum but not nickel?
Hydrochloric acid will react with Aluminum to form Aluminum Chloride (AlCl3) but not with Nickel.
What happens when you put hydrochloric acid on Aluminum?
Hydrochloric acid + Aluminum ----> Aluminum chloride + Hydrogen6 HCl + 2 Al ----> 2 AlCl3 + 3H2
Does neon react with hydrochloric acid?
No. Neon is highly unreactive. No ordinary compounds of neon are known.
Which is more rapid in terms of gas evolution hydrochloric acid added with aluminum or acetic acid added with aluminum?
Possibly HCL, but acetic acid does yield aluminum acetate and hydrogen gas. 3 moles of H2 on the Al + HCl reaction to 1 mole in the acetic acid + aluminum reaction.
What are unreactive metals?
metals which dont react with water or acid are called unreactive metals

If a metal reacts slowly with an acid does this mean that the metal is unreactive?
i don't know...:P
Why doesnt aluminum react with hyrdochloric acids?
Dilute nitric or sulfuric acid shows little reaction with aluminum, but hydrochloric acid dissolves it, giving off hydrogen gas. Remember too that aluminum forms a layer of oxide in air very quickly,which protects its surface. If you test for a reaction in acid, scratch the surface just before the test.

Hydrochloric acid + Aluminum ----> Aluminum chloride + Hydrogen6 HCl + 2 Al ----> 2 AlCl3 + 3H2
Aluminum react with sulfric acid and Which atom is oxidized?
Aluminum.
What unreactive metal does not react with dilute acid?
any metal's that below Copper in the reactivity series.
Does diamond bubble in acid?
Hmm diamond.. I wouldn't think so it's pretty unreactive.
Does neon react with hydrochloric acid?
No. Neon is highly unreactive. No ordinary compounds of neon are known.
Is aluminum foil an acid?
No
What is the scientific name for AlF3?
The fullest correct name is monoaluminum trifluoride. It is often called more simply aluminum trifluoride, or even aluminum fluoride.
