When iron metal reacts with oxygen, the reaction can form fe2o3. write a balanced chemical equation for this reaction, and find the number of moles of oxygen that are needed to form 6 mol of fe2o3 while showing your work.

The balanced equation is 
4Fe+3O₂⇒2Fe₂O₃

We know that the mole of Fe₂O₃ is 6, and since the ratio between oxygen and Fe₂O₃ is 3:2, we can see that

3:2 = x:6 (3 oxygen moles can make 2 Fe₂O₃ moles = x oxygen moles can make 6 Fe₂O₃ moles)

Multiply outside and inside (3*6 , 2*x) and put them on opposing sides of the equation

2*x = 3*6
2x=18
x=9
Therefore 9 moles of oxygen is needed.

The reaction Fe203 occurs when oxygen and iron metal react to each other. The complete balanced formula for the chemical equations will be " 4Fe + 302 -> 2 Fe203. You will need to multiply 6 mols by 3/2 (1.5) and that will give the 9 mols needed to find the number of moles of oxygen that are needed.

Atomicity occurs to prevent updates of the database occurring only partially, which can cause greater problems than rejecting the whole series outright.some are monatomic, diatomic, triatomic etc because it shows the number of atoms. for example, monatomic means it contains only one atom.
