Fe[itex]_{2}[/itex]O[itex]_{3}[/itex]+2Al[itex]\rightarrow[/itex]2Fe+Al[itex]_{2}[/itex]O[itex]_{3}[/itex]

a)Find the moles of aluminum needed

b)Find the moles of iron formed

c)Find the moles of aluminum oxide formed

Not sure how to go about solving any of these the book is terrible and doesnt explain anything and I cant seem to find good notes online.

Im thinking that

a)6.6 moles because there is a 2 infront

b)6.6 again same reason

c)3.3 to even out the moles used
