he following equation is balanced 4Al 3O2 -- 2Al2O3 is not a balanced equation.on the reactants side we haev 4 atoms of Al and we have 24 atoms of oxygen.
but on products side we have 24Al but 6 atoms of oxygen.this violates conservation of mass.

How many oxygen atoms are there in the formula for aluminum nitrate?
The formula for aluminum nitrate is Al(NO3)3, so there are 9 oxygen atoms. Multiply the number of oxygen atoms inside the parentheses times the subscript outside the parentheses.
What does AI2O3 stand for?
Two aluminum atoms and three oxygen atoms >
How many atoms of aluminum sulfur and oxygen are in 3 molecules of aluminum sulfate?
1 formula unit of aluminum sulfate has the formula Al2(SO4)3. So there are 2 atoms of aluminum, 3 atoms of sulfur and 12 atoms of oxygen in 1 formula unit of aluminum sulfate. There are no molecules of aluminum sulfate. They are called formula units.
How many oxygen atoms are contained in 2.74g of Al2SO42?
Mass of Aluminum Sulfate: 2.74g Molar Mass of Aluminum Sulfate: 342.14 g/mol Therefore, number of moles of Oxygen can be calculated by 2.74g * 12/342.14 g/mol = 0.096 moles Now since u have the moles of Oxygen, the number of oxygen atoms is given by 0.096 mol * (6.02*10^23) particles or atoms/mol that gives u about 5.78 * 10^22 atoms of oxygen
Why does oxygen have a subscript of 3 in aluminum oxide?
Aluminum loses three electrons to have a full valence shell. Oxygen gains two electrons to have a full valence shell. Aluminum Oxide is shown as Al2O3 because there are three oxygen atoms with a total of 6 gained electrons. Two Aluminum atoms lose 6 electrons and three Oxygen atoms gain six. This is the balance between aluminum and oxygen.
How many oxygen atoms are in aluminum chromate?
The formula for aluminum chromate is Al2(CrO4)3, so there are 12 oxygen atoms. Multiply the number of oxygen atoms inside the parentheses times the subscript outside the parentheses.
How many oxygen atoms are there in the formula for aluminum nitrate?
The formula for aluminum nitrate is Al(NO3)3, so there are 9 oxygen atoms. Multiply the number of oxygen atoms inside the parentheses times the subscript outside the parentheses.
What atoms are in aluminum sulphate?
2 aluminum atoms 4 sulphur atoms 4 oxygen atoms
When aluminum combines with oxygen three oxygen atoms combine with this many aluminum atoms?
There are 13 protons in aluminum and 13 electrons. So, there are 13 atoms in aluminum. In oxygen, there are 8 protons and 8 electrons. thus there are 8 atoms. EDIT: This answer is absolutely and completely incorrect. (Dr.J.)
How much oxygen in grams will be required to react with 0.5 mole of aluminium?
Three atoms of oxygen are required to react with each two atoms of aluminum to form the most common product of reaction between oxygen and aluminum. Therefore, 0.75 mole of oxygen atoms will be required to react with 0.5 mole of aluminum atoms. The atomic weight of oxygen is 15.999; therefore, the mass will be (0.75)(15.999) = 12 grams of oxygen, to the maximum possibly justified number of significant digits.

How many oxygen atoms are there in aluminum sulphate?
there are four.
How many oxygen atoms are there in aluminum sulfate?
There are 12 oxygen atoms in a molecule of aluminum sulfate. The formula for aluminum sulfate is Al2(SO4)3. This tells us there are 3 sulfate ions, each with 4 oxygen atoms per sulfate, so 3 * 4 = 12.== ==
What is the number of atoms in 1.2 moles of pure aluminum?
The number of atoms in 1,2 moles of pure aluminum is 7,2265690284.1023.
