# *Thermite Reaction*

I have a question regarding the thermite reaction.

The chemical equation for it looks like:

$$Fe_{2}O_{3}+2Al----2Fe+Al_{2}O_{3}$$

If 1 mole of Al is reacted with 10.0g of $$Fe_{2}O_{3}$$, how many grams of unreacted Al would remain?

Would you just convert the 10.0g to moles which would be 0.0626mol and then subtract from 1? Or do you have to us some kind of ratio too?

Thanks!

Basically 1mole$$Fe_{2}O_{3}$$reacts with two moles of Al.

Huh? I don't understand?
