What is the theoretical yield of aluminum oxide if 2.60 mol of aluminum metal is exposed to 2.25 mol of oxygen?
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.

What is the theoretical yield of aluminum oxide if 1.60 Mol of aluminum metal is exposed to 1.50 Mol of oxygen?
To determine the theoretical yield of aluminum oxide (Al₂O₃), we start with the balanced chemical reaction: 4 Al + 3 O₂ → 2 Al₂O₃. From the stoichiometry, 4 moles of aluminum react with 3 moles of oxygen to produce 2 moles of aluminum oxide. Given 1.60 moles of aluminum, we can find the limiting reactant. Since 1.60 moles of Al would require 1.20 moles of O₂ (which is less than the available 1.50 moles), aluminum is the limiting reactant. Thus, 1.60 moles of Al can produce 0.80 moles of Al₂O₃ (from 2 moles Al producing 1 mole Al₂O₃), so the theoretical yield of aluminum oxide is 0.80 moles.
Which metal forms a protective oxide layer on its surface and why?
Aluminum forms a protective oxide layer on its surface due to its high reactivity with oxygen. When exposed to air, aluminum quickly reacts to form aluminum oxide (Al2O3), which adheres tightly to the metal and prevents further oxidation. This oxide layer is thin, transparent, and highly resistant to corrosion, making aluminum suitable for various applications in environments where corrosion is a concern.
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.
How can you turn metal into rust?
Metal turns into rust when exposed to oxygen and moisture over time, a process known as oxidation. The oxygen in the air reacts with the metal's atoms to form a new compound, which appears as reddish-brown iron oxide, or rust. This process can be sped up by increasing the metal's exposure to water and oxygen.
What is the theoretical yield of aluminum oxide if 3.00 mol of aluminum metal is exposed to 2.55 mol of oxygen?
The balanced chemical equation for the reaction is 4Al + 3O2 -> 2Al2O3. Since the molar ratio between aluminum and oxygen is 4:3, aluminum is the limiting reagent. Therefore, the theoretical yield of aluminum oxide is based on the 3.00 mol of aluminum. Using stoichiometry, the theoretical yield of aluminum oxide would be 3.00 mol of Al * (2 mol Al2O3 / 4 mol Al) = 1.50 mol of Al2O3.
What is the theoretical yield of aluminum oxide if 3.40mol of aluminum metal is exposed to 2.85mol of oxygen?
The balanced chemical equation for the reaction between aluminum and oxygen to form aluminum oxide is: 4Al + 3O2 → 2Al2O3. From the balanced equation, we can see that 4 moles of aluminum react with 3 moles of oxygen to produce 2 moles of aluminum oxide. Therefore, if 3.40 mol of aluminum and 2.85 mol of oxygen are reacted, the limiting reactant is oxygen. Thus, 3.40 mol of aluminum would theoretically produce 1.90 mol of aluminum oxide.
What is the theoretical yield of aluminum oxide if 3.20 mol of aluminum metal is exposed to 2.70 mol of oxygen?
The balanced chemical equation for the formation of aluminum oxide is: 4Al + 3O2 -> 2Al2O3. This means that 4 moles of aluminum react with 3 moles of oxygen to produce 2 moles of aluminum oxide. Using the given moles of aluminum and oxygen, we can determine the limiting reactant and the theoretical yield of aluminum oxide. In this case, the oxygen is the limiting reactant, which means it will run out first. Therefore, all of the 2.70 mol of oxygen will react with aluminum to produce aluminum oxide. Since the ratio of aluminum to aluminum oxide is 4:2, the 2.70 mol of oxygen will react with (2/3)*2.70 mol of aluminum to produce aluminum oxide, which is approximately 1.80 mol.
What is the theoretical yield of aluminum oxide if 3.40 mol of aluminum metal is exposed to 2.85 mol of oxygen?
The balanced equation for the reaction is 4Al + 3O2 -> 2Al2O3. From the stoichiometry of the reaction, 3.40 mol of Al will react with 2.55 mol of O2 to produce 4.25 mol of Al2O3. Hence, the theoretical yield of aluminum oxide is 4.25 mol.
What is the theoretical yield of aluminum oxide if 2.00mol of aluminum metal is exposed to 1.80mol of oxygen?
The balanced chemical equation for the reaction is 4Al + 3O2 → 2Al2O3. Since the stoichiometry ratio is 4:3, the limiting reactant is aluminum since it provides less moles of product. Therefore, 2.00 mol of aluminum will produce 2.00 mol of aluminum oxide.
What is the theoretical yield of aluminum oxide if 2.40 mole of aluminum metal is exposed to 2.10 mol of oxygen?
To determine the theoretical yield of aluminum oxide, we first need to write a balanced chemical equation for the reaction between aluminum and oxygen to form aluminum oxide. The balanced equation is 4Al + 3O2 -> 2Al2O3. From the equation, we can see that 4 moles of aluminum react with 3 moles of oxygen to produce 2 moles of aluminum oxide. Therefore, if 2.40 moles of aluminum is exposed to 2.10 moles of oxygen, the limiting reactant is oxygen. Using stoichiometry, we can calculate the theoretical yield of aluminum oxide, which is 1.60 moles.

What transition metal rusts when exposed to oxygen?
Iron is the transition metal that rusts when exposed to oxygen, forming iron oxide.
What is the element that is a self protecting metal?
Iron is a self-protecting metal that forms a protective layer of iron oxide (rust) when exposed to oxygen and moisture, which helps prevent further corrosion.
What is Metal oxide symbol?
The symbol for metal oxides is typically a combination of the chemical symbol for the metal and the chemical symbol for oxygen. For example, the metal oxide formed by aluminum and oxygen is represented as Al2O3, where "Al" is the symbol for aluminum and "O" is the symbol for oxygen.
