iron metal & oxygen combine to form magnetic oxide of iron, Fe3O4. How many mols of iron can be converted to magnetic by 8.80 mols of pure oxygen?
13.2
balance the equation:
3Fe + 2O2 >> Fe3O4
so it takes 3/2 molesFe for each mole O2
so moles Fe=3/2 * 8.8 moles
Writing Fe3O4 as a compound always bothers me when we know it is
FeO.Fe2O3 an almost equal mixture of Iron(II) and Iron(III) oxides.
Well, well, isn't this a classic case of "turning iron into a magnet"? Fe3O4 is also known as magnetite, which sounds rather impressive, doesn't it? Now, let's crunch those numbers!
The equation for the reaction is 3Fe + 2O2 -> Fe3O4. So for every 3 moles of iron, we need a total of 2 moles of oxygen.
Now, if we have 8.80 moles of oxygen, we can simply divide it by 2, which gives us 4.40 moles of iron that can be converted into magnetite. Voila!
So, to answer your question, 8.80 moles of pure oxygen can convert 4.40 moles of iron into magnetic magnetite. Now you can go forth and impress your friends with your knowledge of converting things into magnets!
To determine how many moles of iron can be converted to magnetic oxide of iron (Fe3O4) using 8.80 moles of pure oxygen, we need to use the balanced chemical equation of the reaction:
4 Fe + 3 O2 -> 2 Fe3O4
From the equation, we can see that 4 moles of iron (Fe) react with 3 moles of oxygen (O2) to produce 2 moles of magnetic oxide of iron (Fe3O4).
Let's set up a proportion based on this ratio:
(4 moles Fe / 3 moles O2) = (x moles Fe3O4 / 8.80 moles O2)
Cross-multiplying, we get:
4 moles Fe * 8.80 moles O2 = 3 moles O2 * x moles Fe3O4
35.20 moles Fe = 3x moles Fe3O4
Dividing both sides by 3, we find:
35.20 moles Fe / 3 = x moles Fe3O4
The result is:
x ≈ 11.73 moles Fe3O4
Therefore, approximately 11.73 moles of iron (Fe) can be converted to magnetic oxide of iron (Fe3O4) using 8.80 moles of pure oxygen.
To determine how many moles of iron can be converted to magnetic oxide of iron (Fe3O4) using 8.80 moles of oxygen, we need to use the balanced chemical equation for the reaction.
The balanced equation for the reaction of iron with oxygen to form Fe3O4 is:
4 Fe + 3 O2 -> 2 Fe3O4
From the equation, we can see that 4 moles of iron react with 3 moles of oxygen to produce 2 moles of Fe3O4. Therefore, the molar ratio of iron to oxygen is 4:3.
Now, let's calculate the number of moles of iron that can be converted. We have 8.80 moles of oxygen, and according to the molar ratio, 3 moles of oxygen are required to react with 4 moles of iron.
We can set up a proportion to find the number of moles of iron:
(8.80 moles of O2 / 3) * 4
Calculating the expression:
(8.80 moles of O2 / 3) * 4 = 14.73 moles of iron
Therefore, 8.80 moles of oxygen can convert approximately 14.73 moles of iron to magnetite (Fe3O4).
