Respuesta :

Answer: Thus 9.75 moles of iron will be required.

Explanation:

The balanced chemical reaction is:

[tex]2Fe+3O_2\rightarrow 2Fe_2O_3[/tex]  

According to stoichiometry :

2 moles of [tex]Fe_2O_3[/tex] are produced by= 2 moles of [tex]Fe[/tex]

Thus 9.75 moles of [tex]Fe_2O_3[/tex] are produced by=[tex]\frac{2}{2}\times 9.75=9.75moles[/tex]  of [tex]Fe[/tex]

Thus 9.75 moles of iron will be required.
