Well electrons are like electricity well it is partly if it went 3 sub levels the electrons would blow up some electricty<span />
The balanced equation is
4Fe+3O₂⇒2Fe₂O₃
We know that the mole of Fe₂O₃ is 6, and since the ratio between oxygen and <span>Fe₂O₃ is 3:2, we can see that
3:2 = x:6 (3 oxygen moles can make 2 </span>Fe₂O₃ moles = x oxygen moles can make 6 <span>Fe₂O₃ moles)
</span><span>
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.

Answer:
section 2
Explanation:
it has the shiny silver apperance but at the same time is hard and brittle
Oxygen is gas. It has 2 O atoms. Atomic mass of 1 O atom is 16 amu. So molecular mass of O2 = 2 x 16 = 32 amu.
Now, mass of 6.023 x 10 ^23 = 32 amu.
Therefore mass of 3.01 x 10^23 = 32 x 3.01 x 10^23 / 6.023 x 10 ^23 = 15.99
= ~16 gm
