Mixture
A pure substance is a material containing only one kind of particle. Aluminum foil is a pure substance since it is made entirely of the element aluminum.
It is pure aluminum, or maybe small parts of tin is alloied in it, to get somewhat higher stifness.

Aluminum foil is a pure substance because it is made of aluminum itself! Hope this helped
what is the similarities of the aluminum foil and water as pure substance?
Simple answer: an element. In reality, however, the protective coating of aluminium oxide (Al2O3) effectively makes aluminium objects a mixture of an element (Al metal) and a compound (Al2O3).
No, aluminum is one of the elemental metals. It is Al on the periodic table and it is a pure substance, not a mixture.
Pure substance.
A block of pure aluminum has no parts that are able to be separated according to distinct chemical properties. So, it would be a pure substance.
Aluminum foil is pure elemental aluminum in very thin sheets. It's a 100%, or, to be more precise, 99.99% aluminum.
Only a single component makes up aluminum foil, which is the aluminum element. Hence, aluminum foil is considered as a pure substance.

Aluminum is an element, a pure substance.
Aluminium is a pure substance
it can be salt, aluminum foil, distilled water
No, Aluminum oxide is a pure substance.
Aluminum metal (symbol Al) is an element and therefore a pure substance. That said, if something is made out of aluminum (like aluminum foil) it is rarely pure aluminum and is typically an alloy composed of mostly aluminum with other metals. Alloys are used to improve the properties of the pure substance in various ways depending on the desired use. So, no, aluminum is not a compound.
Not quite, unless it has been manufactured in an inert environment. As soon as aluminum is exposed to oxygen it grows a thin skin of aluminum oxide.
