(Assuming that the numbers given are moles)
For a problem like this, the best thing to do is write a balanced equation. This gets us:
4Al + 3O2 -> 2Al2O3
Now we must find the limiting reactant. That is, the reactant that will result in less product. Using the Coefficients as fractions, we find that 2.2mol of Al should yield:
(2.2/4)*2= 1.1mol Al2O3
Next we do the same with 1.95 mol of O2 to get:
(1.95/3)*2= 1.3mol Al2O3
We go with the lesser amount, so the answer is 1.1mol Al2O3.
Or 112g

What is the theoretical yield of aluminum oxide if 3.40 of aluminum metal is exposed to 2.85 of oxygen?
A theoretical yield is equivalent to a percent yield of 100. In practice, it is very rare to achieve 100 yield from a reaction due to a wide range of outside factors 1.7mol
Does aluminum oxide rust?
Yes. In fact, aluminum oxidizes faster than almost any other metal, which is why aluminum foil will, actually, remove rust: The abrasion removes the coating of aluminum oxide that covers all metallic aluminum exposed to the air, and the exposed aluminum metal wants to be oxidized so badly that it will actually steal oxygen from iron oxide, AKA rust, and reduce it back to iron metal. Which is why aluminum foil will, in fact, remove rust. This reaction, interestingly, is the same one that makes thermite work.
What will happen when solid sodium metal is exposed to oxygen?
The product of this reaction will be Na2O.
Which element is the most abundant metal in Earths crust?
The most common chemical elements in the crust are oxygen (46.6%), silicon (27.7), aluminum (8.1), iron (5.0), calcium (3.6), potassium (2.8), sodium (2.6), and magnesium (2.1).Oxygen is a non-metal and silicon is a metalloid - so the most common metal is aluminum.
Which metal is a member of the boron family and is the most abundant metal in the earth's crust?
Oxygen is the most abundant element in the earth's crust and is not in the boron family. Aluminum is in the boron family and is the third most abundant element in the earth's crust. Refer to the related link for a list of the 10 most abundant elements in the earth's crust and their percentages.

When does rusting occur fastest?
Instant surface rust, much like bare aluminum gets oxydized immidiately.

oxygen is a non metal
What happens when you put water on tin foil?
Aluminum in general is a very reactive metal. So reactive that once it is forged and exposed to the air it reacts with the oxygen in the air to produce a thin layer of aluminum oxide. This thin layer of aluminum oxide prevents the aluminum from further oxidation or rusting. The same thing happens when aluminum is exposed to water. Believe it or not aluminum exposed to water produces hydrogen. The amount of hydrogen produced is so small it is undetectable because once the aluminum is exposed to the water it forms a shield of aluminum oxide preventing further reaction. A way around this reaction block is by making an alloy of gallium and aluminum. Gallium metal is a liquid metal just above room temperature. When gallium is combined with aluminum it doesn't allow the aluminum to form the protective layer of aluminum oxide when exposed to water or oxygen in the air. Allowing the aluminum to continuously react with the water and produce hydrogen gas. I hope this answered your question.
What type of air pollution can cause the metal parts of cars the corrode?
