How many moles of Al2O3 are produced?

3 mole of O2 reacts with 4 mole of aluminium to give =2 mole of Al2O3. Hence 0.78 mole of oygen react with Aluminium to give 0.52 mole of Al2O3.

How many oxygen atoms does 1 mol of O2 gas have?

Originally Answered: What will be the number of oxygen atoms in 1 mole of O2? A mole is 6.023E23 of whatever you are counting. A mole of O2 molecules has 6.023E23 molecules, and each molecule is made up is two atoms of oxygen. That means that there are two moles of oxygen atoms in a mole of O2, or 1.2046E24 of them.

How many moles of Al2O3 will be produced by 4 moles of Al?

3 moles of O2 react with 4 moles of Al to give 2 moles of Al2O3.

How many atoms are in a mole of Al2O3?

Therefore 1 mol Al2O3 = 5*6.022*10^23 =3.0*10^24 atoms.

How many atoms are in moles?

Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number.

What type of reaction is 4Al 3O2 2Al2O3?

decomposition reaction
This is an example of a decomposition reaction.

Is 4Al 3O2 2Al2O3 balanced?

We can see that this is not balanced – there is 1 aluminum on the reactant side and 2 on the product side, and there are 2 oxygens on the reactant side and 3 on the product side. We can then change the coefficient of 2 in front of the aluminum to a 4. Finally we have a balanced equation: 4Al + 3O2 –> 2Al2O3 .

How do you find moles of oxygen?

So, guys, in one mole of oxygen, how many grams are there if you take a look at the product table? Or maybe you remember the atomic weight of oxygen. It is 16 g per one mole, right, so 16 g per one more. So all you have to do is divide 35.2 by 16 and that will give you the answer in moles to to moles of oxygen atoms.

Is 4Al 3O2 2Al2O3 a redox reaction?

For example, 4Al (s) + 3O2 → 2Al2O3 has an oxidation half and a reduction half; oxidation = Al (s) → Al3+ + 3e- and reduction = O2 + 4 e- → 2O2- Page 2 Use the information presented above to answer the following questions. 1. What happens to a) the reducing agent and b) the oxidizing agent in a redox reaction?
