Im pretty sure it’s sharing electrons because it has 1 unpaired electron and if it reacts with another f2 then they share the electron to bond together
The correct answer is Urea
The moles of Al that is needed to react with 6.34 moles of Fe3O4 is 16.9 moles
<u><em> Explanation</em></u>
<em> </em>8 Al+ 3Fe3O4 → 4 Al2O3 + 9Fe
use of mole ratio of Al: fe3O4 to calculate the moles of Al
The mole ratio of Fe3O4 : Al is 8:3 therefore the moles of Al =
6.34 moles x8/3 = 16.9 moles
