Respuesta :

The balanced chemical reaction is expressed as:

2Al(s)+3FeO(s)->3Fe(s)+Al2O3(2)

We are given the amount of FeO to be used in the reaction. This amount will be the starting point for our calculations. It is as follows:

1.2 mol FeO ( 2 mol Al / 3 mol FeO) = 0.8 mol Al needed to react completely

The answer to your question is

0.8mol

I hope I helped
