the answer is 4.7
1] Figure out how many moles of Al and O2 2.5g is.
2] Compare the ratio of the moles from A to the 2:3 ratio in Al2O3; do you have more Al proportionately than O2 or vice versa ? This is called 'finding which reagent is limiting"....
3] Take whichever reagent was limiting and find out how many moles of Al2O3 you can get from it. THen find the mass.

When does rusting occur fastest?
Instant surface rust, much like bare aluminum gets oxydized immidiately.
Which metal is the most abundant in the earth 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.
Is corrosion of aluminium metal a physical process?
No, corrosion of aluminum metal is a chemical process. It occurs when aluminum reacts with oxygen in the presence of moisture, forming a layer of aluminum oxide on the surface. This chemical reaction leads to the degradation of the metal over time.
Does a nail rust in oil?
No, in order for iron to rust it must be exposed to oxygen. Since there is no oxygen in oil oxidation cannot occur.
Is aluminum a metal?
Yes, aluminum is a metal.
What is the theoretical yield of aluminum oxide if 3.00 mol of aluminum metal is exposed to 2.55 mol of oxygen?
The theoretical yield is 56,7 %.
What is the theoretical yield of aluminum oxide if 2.00mol of aluminum metal is exposed to 1.80mol of oxygen?
1.30
What is the theoretical yield of aluminum oxide if 3.40mol of aluminum metal is exposed to 2.85mol of oxygen?
1,7 mol oxide
What is the theoretical yield of aluminum oxide if 3.20 mol of aluminum metal is exposed to 2.70 mol of oxygen?
1.60mol
What is the theoretical yield of aluminum oxide if 3.40 mol of aluminum metal is exposed to 2.85 mol of oxygen?
2,55 moles of aluminium oxide are obtained.
What is the theoretical yield of aluminum oxide if 3.60 mol of aluminum metal is exposed to 3.00 mol of oxygen Express your answer with the appropriate units.?
1,8 mol (183,528 g) of aluminium oxide is obtained.
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

What elements aluminum boron iron and oxygen is non-metal?
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?
