How many moles of iron can be recovered from 100.0 kg fe3o4?

Leokris [45]

Hello!

To know how many moles of iron can be recovered from 100 kg of Fe₃O₄ we'll need to use the molar mass of Fe₃O₄ and apply the conversion factor to go from kg of Fe₃O₄ to moles of Fe in the following way:

$100 kg Fe_3O_4* \frac{1000 g}{1 kg}* \frac{1 mol Fe_3O_4}{231,533 g Fe_3O_4}* \frac{3 mol Fe}{1 mol Fe_3O_4}=1192,68 moles Fe$

So, theoretically, one could recover 1192,68 moles of Fe from 100 kg of Fe₃O₄

Explain what "LEO the lion goes GER" means based upon what you have learned

olchik [2.2K]

"LEO the lion goes GER" means based upon the oxidation and reduction reactions.

<h3>What is oxidation and reduction reaction?</h3>

Oxidation reactions are those reactions in which lossing of electrons are taking place from the substrate molecule and in reduction process gaining of electrons is done by substrate molecules.

The phrase "LEO the lion goes GER" is used in the context of oxidation and reduction reactions. Meaning of the terms:
LEO → Lose electrons = oxidation

GER → Gain electrons = reduction

Hence the given line is based on oxidation and reduction.
